Adcom 7400 schematic sought

[al2002]

Hi All,

I’m Looking for the schematic for the Adcom 7400 5-channel amplifier. The service manuals I’ve seen on the web do not include the circuit diagram.

Anyone know if there was a 2 channel version of this or a related multichannel amp? if so, info would be welcome.

Thanks in advance.

Bump

Anyone?

Thanks.

There may not have been a schematic released for that one.
The circuit should be easy enough to draw out from the board.

Hi rayma,

Thanks for the suggestion. It did occur to me but I am hoping to avoid tracing out the circuit if at all possible.

I've always had a saying: it takes longer to rush.
Never fails, in my experience.

Hi - Bunmer there isn’t a schematic. Based on the internet pictures this model looks to be constructed in 5 equal modules lined up, so you could trace just 1 to get the knowledge.
What’s your objective? Just curious as a guy who has a LOT of Adcom gear…
Good luck!

Ask @CharlieLaub if he knows more about this amp.

I just want a schematic so I can repair in the future it if it ever goes wrong. nothing more than that.

Andersonix, Charlie doesn’t have the circuit diagram either.
