QED A 240 SA Restoration Project
 
I recently purchased this amplifier as a winter evenings project it is in a very unloved condition both channels not operating has anybody got any information they could share with be for this amplifier schematics etc .
I have previously restored some other older amps like the Magnum IA120
A&R A60 with good results.
I have no information for this amp and would appreciate any assistance.
Regards P.Allan.

Thank you Ian that looks like a good start for shure and answers some questions .
the one i have appears to have been got at already as the outputs have been replaced with
MJE2955T and MJE3055T so i will replace these with the original BD911/12 types reverse engineer a schematic and check my way through the rest of the amp.
Thank you again for your reply.
Regards Peter.
