Hmm. Hopefully something will help get back on track. I call this era of amplifiers"Mystery Amps" usually. you never know if you get one thats excellnt working or a hit and miss, or even one that last more than 6 months these days. Shame I still have some 25+ year amps that still work excellent with no cap replacements or leaking and perform well to this day? Kinda strange really. i guess storing indoors in great temps has worked within my favor.?No idea... Going to see if I can get a new end plate from Ruthless.
