Woohoo! Thanks ...
Just cancelled my Wintron order from January.
Any ideas on the European distributor mentioned?
Cheers,
Steve.

Before considering buying any from Simon, please read all threads on RGVAC
about this and make you're own mind up whether you want to buy one from him
or not.
I personally will not be, and would rather pay a slightly higher price after
having my eyes opened on RGVAC.
By the way Simon - nice cut and paste on describing Ferroresonance * .....

Do you really think I care or know anymore than I have read about ferroresonance? Is it now illegal to quote something that you have read? So how do you learn about anything? Oh I forgot you are the oracle right.
I never claimed to be a transformer designer did I, I understand as much as I need to know about the operation and characteristics of the amplione transformer and its regulation.
If I knew everything there was to know about ferroresonance do you think I would be wasting my time with all this? no.
You entitled to your opinions but that all it is an opinion.

To set the record straight as Oliver seems to know so much about all of this I will tell you exactly the chain of events that led to this final product.
Mark S enquired to Hoveyking about a red replacement, after a few emails, probably a little sketchy as sometimes the English is very bad, they speak Mandarin, Mark gave them the details of the pin spacing and casing size so it would fit the amplifone PCB.
Now Hovey (the manufacturers) emailed me asking me to test Revision A as they had been told by an American that is was a worker. I received Rev A and tested it. All the voltages were wrong so I set about mapping the voltages and given frequencies..the amplifone will go to about 32Khz (?lowest voltage) to about 25khz(highest voltage).
The problem as has been pointed out on the RGVAC is the amplifone HV is regulated by the transformer itself unlike the WG6100 that has a feedback from one of the outputs for the 180v for the colour guns which makes it far easier to work with. In fact the red can seems to be part of the tuning used to get the transformer in the correct harmonic. I'm not claiming to be a scientist or know anything other than basic electronics. Now there were no version of this transformer before ver A so I worked on the first one, I didn't "stumble" on it, I was asked to test it. A while later Version B was made and I went through the same process, I also dissected an original Red transformer to give Hovey the details of the core diameters, wire lengths and gauges etc...no one else had done this. Hovey also used a widely available schematic of the wintron to help design. Then version C was made and again I mapped it and gave them the results. I also provided a working amplifone HV board for hovey to analyse, along with the amplifone schematics again available on the net.
Version C was wrong Hv too high, heater voltage too low, focus voltage too low . Another problem was the focus voltage as this feeds the focus/brightness and also runs to the over voltage circuit, unless this is correct the transformer could run over 27kv and produce harmful X-rays....not good!
Version D came and was wrong, version D with a faster rectifier diode came and was wrong, Version D actually worked if you adjusted the colour bias and drives as the b+ voltage was too high. The HV ran at 22kv but was in a safe range. This wasn't ideal as it needed to be a drop in part.
Version E came and had the focus voltage too high causing problems with focus and overvoltage protection.
Then came Version F, this one and at last after 9 months of testing and hundreds of emails to Hovey it worked.
This transformer has had many casings, some that fitted the PCB and some that didn't, the final one is a common casing used by many monitors, you will see it has its focus and screen controls blanked off.
I had many emails with Mark S as he contacted me after I emailed the vectorlist with my test results for version B, he seems like a nice enough guy and I have no problem with him.
There are many thread on the RGVAC about all this and as I had been given version F by hovey before anyone else they were a little surprised that it now worked. They remarked it was unsafe and had not been tested,,,,,not been tested by anyone other than myself. Mark will sell some transformers and I will sell some transformers. Should I have waited for other people to have found this out before I offered it for sale? maybe, maybe not
Now am I the maker? no
Did I design it? no
Do I fully understand ferroresonance? No.. not many people do.
Did I provide the data that led to the outcome of this transformer? Yes
Did I spend many nights fitting/testing and writing up results for this project? yes.
should I have as much right as anyone to sell this product? damn right
Should people that have no idea how much work I put into this make judgements about my morals? No but I'm sure they will.
I'm not going to apologise for the work I have done. If you feel I have stolen something then you are wrong.

1. Mark designed the HV replacement.
2. He contacted Hovey about it
3. They, being Chinese, posted the HV for sale on their site although
it wasn't ready yet.
4. You got 'Google lucky'
5. You're selling his design even though he's still in the testing
phases.
You're a real class act. You've never admitted publicly on RGVAC that
Mark designed it, I urge anyone to read the various threads on RGVAC
about what a total arsehole this guy is.
From all the threads in RGVAC it's clear you've done precisely FUCK
ALL and are selling these trying to make $$ from it. You're even
undercutting the guy who designed this replacement - you're a total
tosser.
Thanks,
/o

I'm not prepared to wade into this already volatile argument with a I say this, I say that, but I'd just like to add that under an unexhaustive pressure and hostile posts I hear from Simon's posts what effort he's put in and I hate to have a go at other parties but it did sound like after 4-years it was a never-never project and Simon picked up the reins and beta tested and ran with.
I say the guy deserves some slack in all this, and I know hes got a technical head on his shoulders that pales me into shame and so frankly his word is better than mine, and therefore I'd just like to say a quick thanks to Simon for his efforts and look forward to getting some HTs from him in the near future as I trust his skills.
I just see everyone kicking a man down and sometimes wonder if at times we're too unhospitable in a collectors scene where we try to encourage solutions and want solutions to things as "red is dead".
As I say, I'm not trying to side, not trying to stir anything up either, but I do feel the flaming is incessant and somewhere I missed why he needs stoning... If so (two flats and a packet of gravel)
Cummon! Lets eat quiche, build bonfires, hug trees and wc90 pcbs and move along!

And on top of all this, before even version A had been made, I asked Hr Diemen, a German transformer manufacturer to make this transformer. They told me they could make it. I waited months and months and in the end they told me they were not actually making it but would be buying some from another source. I guess this is where Hoveyking got my email address from. I knew nothing about Marks request to Hovey. If you had read the vectorlist you would know all of this.
FWIW HR Diemen is a Spanish company they wont produce anything that
isn't going to be a large run.

Wow! nice bit of investigation work there Simon.
I would have given up after the first one, I really couldn't be arsed with
all that testing.
I can't be bothered to read the rest of these threads but I can vouch for
Simon as I have had a few dealings with him in the past AND he knows his
stuff.
Andrew
P.S can I have a free SI boardset please ;-)

If anyone is interested, i would look this up on the newsgroups and
read the threads. Simon has obviously put a lot of time in on this
project from his point of view, but its all originally based on
somoene elses' work.
Also, Simon has been unable to answer critical safety questions by
providing technical data on the core properties and his calculations
for everything...
Although i would say that i don't think there is likely to be a
safety issue, the fact that simon has done inadequate testing concerns
me. If he has done adequate testing, he is unwilling to share results.
There is a big question hanging over core saturation, if Simon can
answer how and when the core saturates, under what operating
conditions, and what the results are then a lot of people would quiet
down.
In order to have carried out a sensible amount of safety testing in
the period of one week since you had the last prototype, i would have
expected that you would have had 5-10 transfomrers running in games
24/7 in different conditions to properly test them, can you provide
any evidence of your testing methods?
I also believe that Simon has fielded most of the questions about
these safety issues with the utmost immaturity and arrogance, and with
scant regard for the members of community that helped get this project
to where it is right now. Not to mention that when asked a technical
question, his response has been to copy and paste answers that he
found by googling, typing mistakes and all.
I read all the threads last night on the newsgroup, and that is my
conclusion... I just suggest everyone else read the threads themselves
and make up your own mind.
Andrew Hannay - please read the threads before adding more fuel to
the fire. Yes it looks like Simon put a lot into this project, but
this is a very critical component that requires a lot more testing
than just measuring voltages with your multimeter.

Lol thanks Andrew, yeah it has all been blown out of proportion, mainly over money because someone on the other side of the pond wanted to make more money out of it.
Once I have paid freight, customs, Vat and all that stuff there won't be any money in this nor was it my intention to make lots out of it. I really enjoyed getting this thing to work, the same as repairing old games. I rarely play them but its great when you fix one.
I have nothing against Oll as I don't even know him. Sure he is entitled to make up his own mind but to insult me I feel was a bit out of order.
How many SI boards do you want? I have a box of about 20 sets in the garage that will most likely stay there as whenever I fix it set it always breaks a few hours later.
They are all 3 board taitos.
Paypal me £40 and I will stick a set in the post for you. They may even work!
Cheers

Ok once again to clarify things.
I didn't make this transformer, Hovey did. They made it based on the results I gave them plus data from 4 Red transformers I tested over a wide range on a modified Amplifone HV PCB.
How did they get it right? I don't know as I don't make them. Have they got it right? well I would say so as my monitor has run non stop for over 72 hours with no problems.
As far as being dangerous? Well unless someone purposely bypassed the over voltage protection circuit then there is no chance of harm. You know as well as I do how that works and as the feed for originates at the Anode, dropped down to around 6Kv for the focus then if the Anode were to rise it would shut down.
The original Amplifone transformers vary in their operational frequency so as far as "ultra tuned" goes, its not very Ultra!
At least I tested my sample, the US guys put theirs up for sale less than 24 hrs after knowing I had offered it for sale so it would seem they are either trusting my results or not bothering to run it for any length of time.
Oh and the spelling thing, Unfortunately, for me that is, I am dyslexic. I apologise for that but its very frustrating for me.
I still need to send you those SI panels, have a million and 1 things to do!
