Thanks for looking I know this is a tough one if only because the amp is not well known. I'll eventually just replace the tubes and hope nothing goes nuclear on me !!
Ekco EV55 using 6550's in place of KT88
I purchased an EKCO EV55SE from a fellow Audiogon member and since then I've been trying to find out if I can substitute NOS GE 6550's for the KT88's ? I swapped the EKCO labeled KT88's for a quad of Gold Lions but really want to try the GE's also. The previous owner has been a tremendous help going way beyond anything I could ask for. I've contacted IAG via email on a couple of occasions and even called a dealer in the UK but can't seem to get an answer. The previous owner suggested contacting USA Tube audio as they are a supposed dealer. Well, that was a lesson in futility. No help they just trashed the amp and tried to steer me to another product line they carry. I believe the swap would not be an issue but would like to get some verification before I swap. Don't want to hurt the amp nor lose a tube or two as a result. Thanks.
