Martin,
I had an original Alpha 77 at one time and one of the Russian 40uf @ 5000
volt oil filled that was the same physical size as the 25uf in the
Alpha. At one time you could get these for around $100 or so. You might
check with KE9PQ. At one time he was a good source of these..

Some weeks a go I mentioned an Alpha 77 that a friend and I were going to
check out. In examining it we paid attention to the comments made by others
on here about what to look for, in particular the filter capacitor. What we
found was a pool of oil under the amp and a greasy film on the diode board.
It will all clean up but the cap is done for we think. Apparently Alpha
power want $800 but they have directed us to Dahl's who still want $400.
What we are thinking is that maybe there are alternatives.
Will a suitably sized bank of electrolytics do the job?
Can oil filled caps be re-conditioned?
Does anybody have something that will do for a 'sensible' price?
Any ideas?
