In Reply to: RE: Tube dampers etc. posted by Lew on April 11, 2016 at 10:34:41
In my journey thru 'N7s decades ago, my first good-sounding find was the RCA, but that was quickly replaced by the KR VT-231/6SN7; to me the KRs were a little warmer balanced (a positive) and lacked nothing anywhere else. But then I found the TSRPs and discovered an even-more-attractive tonal balance and overall excellence. I had over two dozen years ago but then I had nothing to use them in and sold some; I was down to 15 until I bought the quad pictured below. But they too can be microfonic.
I'm retrieving a pair of Atma-Sphere M-60 monoamps today and plan to use probably two TSRPs in each amp.

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.
...$75 and warrant that it's not dead, e-mail me at jeffreybehr(at)cox(dot)net.

Anyone?
Jeff, I sent you an email re the single TSRP.
...I gave up on everything else.

I may have mentioned I found a NOS pair of these in my 6SN7 stash, with the gray smoked glass. They tested as new on my Hickok, whereas only one of my remaining KenRads had not previously seen duty in the MP1, which means I took them out of the MP1 at some time in the past, for some reason, even though they test well. Anyway, I decided to try the RCAs last night. I am very very pleased, especially since these may have been sitting on a shelf for the past 60 or more years. They sound lovely right from the get-go. Bass and midrange to die for. And lack of microphony makes them a bit better than the microphonic KenRads I just removed, which could get shrill on high frequencies. From memory, these sound better than red-base RCA 5692s, of which I have many. I am happy.
