What tube or tubes would make the biggest change in sound on this amp. The GZ-34, 7199's or the EL-34's. This amp is a Dynaco ST-70 rebuilt by Will Vincent. Also what would i gain or lose by using KT-77's instead of the EL-34's? Thanks, Tommy
If you purchase your output tubes from Kevin Deal: you'll never have to worry about getting "stuck", in ANY sense of the word. He's first class, all the way: (http://www.upscaleaudio.com/view_category.asp?cat=86)
Thanks for the link Rodman, he has alot to choose from. I just ordered a quad of the winged c Svetlana el34's. I'll post once they arrive and i have a chance to listen to them. Thanks guys.
I got a pair of RCA 7199's from my local dealer yesterday. All i can say is WOW. It's like a whole new amp. Alot more detail, but still sounds smooth. Now i really can't wait for the new EL-34's to arrive.
