Owners of the Alpha 87a should be aware that static discharges or RF back into
the amp from another source during stand-by can fry the PIN diodes. Alpha
belatedly has a fix with two parts, available from Alpha. I have fried three
sets of PIN diodes over the years but maybe someday, when Alpha responds to my
order, I can replace the latest set .... A pair in the whole set are not
cheap... $125 each, about.
Probably, owners should explore this fix.... sorry but I can not quote the
details from memory, but you experts can get the notion, I am sure....
