Yamaha CA-600 New transistors, New capacitors; just needs a New home. See Video!

Enjoy 30-35 watts of pure clean vintage sound. 

All of the capacitors have been replaced except the two larger power supply caps which tested fine.

All of the problematic transistors, particularly those with a tendency to leak or grow noisy, have been replaced with better modern ones. Mostly KSC1845 and KSA992. 

The output transistors have been upgraded to brand new Onsemi MJ21194G/MJ21193G purchased directly from Mouser. No counterfeits here. And the sound is beautiful. 

Even though this is a vintage unit, it should be good to go for the foreseeable future because of the above work that was recently completed. But this silver-faced charmer retains that vintage sound because no circuit modifications have been made.

All functions work as they should.

Cosmetically, the face looks really good for a piece of this age. The cabinet has a few defects on each side. I have tried to capture them in the photos, so be sure to take a look. There are two indentations in cabinet on each side. I’m not sure if the unit was secured in a cabinet by some sort of fasteners or what. They don’t bother me, and you certainly cannot see them once the unit is in a rack, but I don’t want anyone surprised; the photos are important.

Please let me know if you have any questions.
