Readable BK 467 schematics ?.

Does anyone have a decent scan of the schematics from the manual ?.

I just went to use mine and noticed a loud buzzing so thought I would run through the calibration steps from the service manual to check it out. The heater voltage is around 25V

. Downloaded a copy of the manual but I can't make out what is going on in the circuit diagram, the resolution is far too low. It looks like the heater supply is fed through a load of series diodes to drop the voltage ?, dunno, it just looks like a blobby line.

Yes, I think I have that

Ah ha !, not what I was looking for but very useful. It is an up to date list of tube types against adapters. That would have answered my question the other day.

Thanks.

Oops, I saw B&K and missed the word "schematics"

Sorry
