ok i have this tube
monitor- novel a68cpbb02x20 shanghai

29” h orizontal = 1 ohm 0.33mh
vertical = 7 ohms 8.6mh

i have read that it should be accompanied by the sanwa kw0606

but can i use ms929 or roddotron 666a ?

its not far off the yoke specs of both, consideration to heater current needs to be made- normally a resistor value change

obviously check the neck pinout matches

i have a 10w 1 ohm ceramic type ?
cheers gunblade
i would have replied sooner but feel asleep right after message...

i is this value /type ok to reduce heater voltage ?

it’s a sinlde focus kneck

i have original chassis but it’s from a hybrid tv /monitor
i have given up on the tv type chassis after i found out tube is in the sanwa pfx range
so i’m trying to find a chassis
i have ms9 29 may need a service
i have 29e31s to sure about h v resistance values on this

i would suggest trying out a chassis and seeing what the results are, if its far too dark a picture then half the heater resistor value and vice versa

if the chassis matches ok you will have correct range on horizontal adjustments, if vertical are out then again that can normally be resolved by a resistor

is this tube a pure flat type?

yeh i know what you mean.

i got a few around me and i can’t even find the time to look at them
still sorting a bit space i messed up and filled all my space...
i can’t move in my 2 sheds.... so just sorting a bench one side
i got five on go

ms8 not sure checked hots
ms9 not sure checked hots
samsung + wei ya 2931d you fixed last year thank you it’s working great... but i bought green stick of death to degauss going to try to sort geometry etc i have build a rgb s through vga db 15 to try to feed it 15khz mode..

the novel shanghai sanwa pfx pure flat will try a few chassis with it for results heater resister swap etc...

19” kortec caps
hanterex 19 no static no thump but something powers on...

3 sanwa 29” on shelf

degauss wand going to try to sort some colour issue & geometry etc i have build a rgb s through vga db 15 to try to feed it some 15khz mode.. as i have confirmed vga 31khz

where is good place to measure the heater voltage ?

should be like around 7 volts ?

19” kortec caps
hanterex 19 no static no thump but something powers on...

3 more sanwa 29” on shelf
10 chassis

plus the 13 currently residing inside my
cabs that keeps me on my toes,,,

not to mention the 4 pvm
and melviews bbc x4
mitsubishi mega 38”

got a tube in van outside i’m going to be sneaking it in flat today past the missus up the ladder in loft where i’m setting up
chuksins pc to 15khz calamity groovy mame set up...

next purchases for bench hakko de-solder & a variac & a good solder station,,,
