MC2505, driver board

[peterberlin]

Hi all

I have bought an old MC2505 with a defect driver board.

The schematics did not tell me something about the industrial part number of the transistors.

I was wondering if anyone can tell me if there is a replacement for the transistors:

Q132-070 and 132-054

Or (at the best) with a listing of replacements for all the semiconductors.

I just crawled the net without success...

Thanks in advance

Peter

132-070, NPN for outputs, MJ15003.

132-054, NPN for diff input pair, MPSA06.

Drivers are RCA 40409/40410, hard to find.

Dear Peter,

I am also an owner of mc2505.
I am looking for the schematics to replace the old electrolyte capacitors.
Do you mind send me a copy of schematics of mc2505?
Thanks for your kindness in advance.
by the way, mc2505 is a good amp, congratulations!

best regards,
Frank
