Title: Help with a power amp schematic?
Post by: tpatton on October 01, 2011, 10:52:23 AM

I could use some help with a power amp schematic, Quad II, that I could email to any takers.  I'd like to know in particular which film caps deserve the most to be upgraded.  You could email me at [email protected], and I'd respond by sending you the schematic.  I'd be most grateful: this is not the first time that my ignorance of circuitry has gotten in my way.  Thanks in advance!

I'll take a look.

I have not seen the schematic for the Quad2 amp for a very long time, but if my memory serves me right, the output caps is a good place to start. I believe there is a .1mf cap there. I have about 5 of those amps around somewhere.

Don't forget snubbing the diodes in the power supply (and ultrafast diodes.)

This is an interesting project. I'd like to see the schematic as well.

To see the schematic, go to triodeelectronics.com and see online index for schematics, and click on quad 2 amp.

Just checked out the triode electronics site. I could spend the rest of the month just checking it all out. Great stuff!
