How Often to Re-Cap?

[JimRayden]

Thanks for the info, this helps alot for me.........    The reason I think I need to replace those caps on my amp is that the amp not being as loud as it was like it was pushing a few mili watts, plus that it was made in the 80's and has never been recaped.....  I checked all the in and out connections....  I replaced the tubes and it did not do the trick, also when I discharge the caps there seem to be little spark.   So hopefully it is just the caps...

I don't think faulty power supply caps cause lower power output.

First thing to do, as with stompboxes, is to measure the plate, gate and cathode voltages. I advise you to do some research before doing it. Go to www.ax84.com and FIRST READ THE HIGH-VOLTAGE WARNING. Then go to the Discussion Forum and post the problem over there, see what the pros tell you.
