RE: Lew, have you given the Tung-Sol roundplates a serious evaluation?

I don't use 6SN7s in the input stages of my monoblock amplifiers, but I do use them in my MP1. Last night I was going through my stash, and I may at most have only one TSRP. (Until last night, I had no idea what "TSRP" stood for.) I do have a plethora of KRs (mostly used and of several different origins), Brimar CV1988s, and Raytheon 6SN7WGT. One sample does not cut it. I may try any of the others; it's such a pain in the butt to dismantle my MP1 in order to change tubes that I prefer to make a decision however empirically and stick with it until the tubes go bad, as is the case now. I already use the Brimars in the circlotron section of the MP1.

I've got RCA 5692s, too. But they seemed a bit dull last time I had a listen, albeit that was not in the context of the MP1. A few Syls and GEs, too.
