Sugden A25B

kris1342 · 2nd May 2010, 12:28 PM

Can anyone help with a circuit diagram of the Sugden A25B. Bought it a while ago on Ebay and only just got round to using it.
Both channels are distorting. It is in a common section as all inputs are affected.
Could always trace it out, but that is rather lengthy.
Also, any suggestions as to the op-amps used - the code has been blacked out.
Thanks

Hello kris1342,

I wish I had seen your post earlier.
Do you still need the A25B schematic?

Regards,
