So I got a pair of RCA 6as7g from a huge tube seller on eBay. (Over 9k feedback). Start warming them up in the woo. I get that same horrible noise as I did with the Ei ez80's. Power amp kicked into protect mode immediately. Pulled them out. Replaced with tung sol 7236. Wa2 warms up just fine. What is going?!
Did I actually damage the wa2 with those ez80's. Something that can't charge up on first power up maybe? I just doubt that I got another pair of bad tubes. Or am I really that unlucky? Is the wa2 sensitive to brand new tubes? Each of the sets was sold as NOS. I don't want to keep troubleshooting if I'm going to do damage.
Any help would be appreciated. Thanks
I had the same thing (see a few posts above), also with RCA tubes from the 50s. Turn out the lights and you will occasionally see a tiny flash around the lower radiator. I trashed them because they kept doing it.
