330a

I'm in the process of recapping my 330B (B-2) and found that the schematic is wrong for some of the transistors. As a result I'm trying to determine what I can replace the transistor that has the labeling C1384 R 4B on it. I had planned on replacing the 2SC538A (C1509 R 3H) with a recommended...

I’m working on restoring a Harman Kardon 330a amplifier that was blowing fuses due to multiple shorted transistors. Among other issues, one of the four CDC8002/9002 “flying saucer” transistors was blown. Following advice from an old thread on a different amplifier model, I replaced all four with...

Crew- I have another 330A, dead right channel, here's were I'm at. Initial testing revealed TR904 was bad so I replaced all four output transistors with 15034's TR608 & TR606 tested bad as well, replaced them with 1220 and 2690 (also replaced on left channel, I did this will all components I...

The third era of solid state stereo receivers from Harman Kardon centered around the 330A and 330B and the clones made by Roland and Soundcraftman: This thread is a guide to those models, their specs, and pointers to schematics and restoration threads for each. If you have additional...

Just to keep everyone guessing, I only replaced the electrolytic caps in this Harman Kardon 330A instead of replacing everything I could desolder. ;) For those of you who just want to do a minimal recap and you have the matching 330A, then this thread should help find the right parts to return...
