Ric

Hello Ric.
Have You got'n Your amp up and running?
I have repaired one some years ago. The most difficult part to get was the LM3100 or CA3100 integrated circuit. The connectors between the driver board and the power board, was dirty, and had to be cleaned. As output transistors I used MJ15024 / MJ15025. Regards Soeren Poulsen Denmark
 
Cervin Wega A1800

Hello Ric.
Well, I kind of recognice the situation! If I start to mention the number of fine power amplifiers I have, waiting to be repaierd, I will fill this area!. I have an A400 waiting to be repaired. It is kind of like the same schematic. I have the component placement and some picture of the heatsink with the output transistors. Thats all, so I would be very glad to have the schematic of the driver board with the CA3100 ic. On another forum I have just picked up an old thread about an old Rodec HDA450 amplifier. Funny, people have not recognised, that Rodec made a bummer in that amp, They have put the current sharing emitter resistors in the collector of the lover output transistors!
Regarding the Cervin Wega: Is the driver transistors obtainable?
