I struggled for a few years with an Eico HF-60. I finally put it on variac and lowered the Voltage and re biased according to original spec. And viola!! all my troubles were over. Absolutely glorious sound ever since.
The problem was my house puting out 125V's and the Eico hated it, even with adjusted biasing. I have since built a bucking transformer that puts out 112V's and all is good.
BTW... beware of the cheapo Volt meter on Ebay. They are not accurate(see pic).
