hi all,
I'm working on a vibrolux reverb AA270, and it is clipping in it's phase inverter with the amp turned up above 3.
now I know this is not the most clean amp fender build but in this case it looks like there is something seriously wrong in the phase inverter.
what i did so far:
-isolate the phase inverter from the rest of the amp put signal on it.... no help
-different tubes
-beefed up the psu
-changed caps and resistors
-increased B+
-looked helpless around
even that last action did not help
my question is What kind of peak to peak readings could I suspect from this phase inverter without clipping.
and what possible solution is there to get this amp more clean at reasonable volumes...
thanks in advance
