Default what normally

does that i wrong adjustments and oscillation.....

all your adjustments might be correct and according to the manual but if the values of componets of your amp have been changed cause of age then you have a problem ....

if your caps are old enough that they have obvious external damage then there is no question ..... first you have to "follow the manual "

all caps have to be replaced and since your amp is exposed to thermal stress and age then i would look at resistors to to locate drifting ....

Well, my 2235B lives!
I replaced all the electrolytics, diodes, and transistors on the PS board. That seems to have taken care of my problem. The DC offset is good, and stays good and the heatsink stays cool to the touch.

Now comes the best part... It sounds GREAT. I ran it with a pair of Dayton BR-1's and I LIKE IT!!!

Next project; HK330 with a right channel that's fried (smokes until the fuse blows). This one should be pretty simple. The left channel seems OK, so I'll just compare the two and rebuild accordingly.

Thanks for the input and suggestions.
