Hello all,
Several years ago, I was given an SB-220 which I was told was dead due to some unknown problem. I ground mounted a multi band vert with lots of radials at the 'lake house' and figured this would be a good time to resurrect this amp for use there, when I'm not catching fish 8^).
While looking for a troubled previous life, I expect to re-cap it, replace bleeder R's and PS rectifiers.
I have LOTS of 390 mf/450 v caps which I can use. If I use these, I will add HV inrush circuit.
Any suggestions on what other mods I should do?
