Yes Rich thanks for cleaning up the posts. I agree it was getting ugly. The amp is working fine with all new trannies [ thanks Rachel] , caps and resistors. Same circuit. It NEVER was the amp it was the Full music tubes all along. My mistake was not sending them back right away.
My advice do not buy a new production tube with only a 30 day warranty. Any tube worth its weight especially ones that cost over $400 per pair should IMO have a 90 day warranty minimum. Not 30 days from purchase date. Never again.
My Cyber amps are over 5 years old. Opera gained a customer for life with extending a very fair price for all six trannies. Much appreciated. I'm buying a tube tester.
This is my last post on the subect, which I'm sure makes all happy. I hope it does not happen to you.
