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..


73 and good luck,
