Cool!
So the only non standard things are the main supply caps, signal coupling and feedback, and opamps?
Glad you got there in the end
Yep, bang on! and the IEC.
I've been looking back at you PM regarding the amp. This one......
*Begin with replacing the main PSU caps with the Mundorfs.
*Upgrade the regulators, and rectifier diodes.
*Then try some different caps in the signal path (film are best).
*After that have a play with the poweramp feedback cap.
*Then finally try some different opamps.
The mundorfs are done, however they're 50v with only 3v headroom so I'm looking for the 80v versions at the mo.
Signal and feedback caps are done (silmics)
Opamps are done (LM4562's on sockets)
Just leaves the regs and diodes. The main (x2) 4 pin rectifiers are KBU 8D by HY and the pre amp rectifiers are DB104 again by HY.
Any ideas on what to replace them with??
I'll jot the reg numbers down soon, will be looking for better std regs rather than discrete modules like the classD's.
Danke!
