Wish they were original Telefunkens. Tubes were replaced. Like you, i was thinking she was pretty unmolested.
suggestions on a good set of tubes for the PAS and ST-70? Does Mesa Boogie make their own tubes?
Follow Ups:
As far as I know, Mesa Boogie does not manufacture their own tubes. I suspect they have them made in China to their specification or they just relabel Chinese, JJ or maybe some of the New Sensor tubes.For current production 12ax7, I find the Mullard to be on the warm side while the Tung Sol is more extended and lively. For the phono section, the Sovtek 12AX7LPS is supposed to be a good choice because they are quiet and sound good besides. Buying them from a good tube seller is important, too. For 12AX7 tubes, I like McShane Design and also ebay seller jspht8338. At one time, both were willing to sell me small quantities of matched/balanced 12AX7.
As far as tubes for the Stereo 70, it kind of depends on what configuration your Stereo 70 is in. Is it the original circuit or has a different circuit been installed? Photos?
