Bedini Schematics for Class A Amp Models 802 & 803



I have a Bedini 803 with a slight hum in one channel and I have two Bedini 802's that are inoperable but obtained for parts. Both are loaded and haven't been cannibalized.

It is my desire to rebuild the 803 and 802 but I am in dire need of schematics. Would anyone have an idea as to how I might obtain them?

Any help would be much appreciated. Thanks, Mike

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.
John Bedini,  
Please! Can you confirm the speaker's fuse size. 
I have on my BA 803 are only 2A fuses for speakers protection. Please verify. Thanks.
How could anyone who knows anything about electronics say a Bedini amp has poor quality parts......You don't know what you are talking about.....Some of these amps have been playing for 40 years.....I have a friend that never turned his 100-100 off ..........Thanks
