Thanks Graham,
My old 100w VS combo uses 2N3055 as O/P's. I must compare the specs of both the 3055 and the 3773. The latter might be a better replacement if I ever need to replace the 2n3055's in my 100w.
By the way, I got the MA150 running ok with help from Enzo and others on this site. Replaced all the electrolytic caps that had high esr readings while I had the unit on the bench. It's back gigging again.
