Hi Mike,
schematics for Bedinis are in Johns head. There are no written or printed materials. They are difficult to deal with to get any kind of info. I have spoken with John various occassions, & it is a real lesson on your patience level of stress. I used to own an 803 before it got taken from me. I now have an 801, 100/100 , with an issue I think possible bad xformers,& a 150Mkii in mint condition.
The hum you have, do you think you might have a grd or xformer issue? Have you replaced the caps in power supply? These amps are very musical, but they lack really quality parts in build quality. I love these amps but they need some tuning up to bring them to the next level.
If you have any info on the amps, it would really be appreciated!
Best Regards
Ronnie

Bighume,
The 802 and 803 Amplifier uses Bus fuses ( MDL 8 amp fuse). But if that fuse has blown you may find another problem. The Amplifier does not use any form of protection circuit, so your dependent on the fuses. The bias on the amp is measured across the .47 emitter resistors and is set to 35 Ma do not exceed this measurement. if you try to set this let the amp warm up on load resistors no signal input. If you see hum then the dual differential front pair could be damaged.

John Bedini,

I have one of your 45/45 amps. It is a very sweet sounding amp. I never found much info on it, can you tell me any details on it?

It is a "very" early serial # and I did speak to you years ago regarding disabling the fan or slowing it down and you mentioned something about the early ones being "single ended?" something or another.

Appreciate any details you can give me about this amp.
