Jim, Isn’t it the same as the famous European E55L? If so then it is a very popular in certain circles tube and it is a good driver. I never tried it myself though and I can not comment about it sonic signature or how to use it. BTW, the way how you ...

Yes, it is an E55L. I wonder how stable it is. Interesting to me how many of these "uber-tubes" are designed for RF operation. Should make a wonderful oscillator. The other find I came across was a pair of 6CL6. Makes me...

Hello first, as I am new on this site...
I have tried a number of high Gm pentode/triode tubes, including E55L and, of course, 7788. All are very linear when used as triodes, but do not bet on very low noise, if that is what you would be after. Th...

hI bRIAN, [quote user="Brian Clark"]The 834P was a revelation for me, being a circuit that I would have dismissed as "old hat" (Feedback? 12AX7 cathode follower? Do me a favour!).[/quote] Me too, but you know me, i'm mainly pragmatic. The EAR 834P is...

[quote user="Brian Clark"]I like it so much that I intend to build an "enhanced" copy a la Thorsten/Carsten for reference (and enjoyment!) before investigating the high Gm alternative (D3a + E55L or E810F )[/quote]Brian, It is hard to say. I use my b...

Hi,[quote user="morricab"]You may be right. It would perhaps be worthwhile to look into "better" transformers but I am not sure that an advantage can be found over just going RCA to XLR adaptor into the balanced inputs and thereby bypassing the...

[quote user="Thorsten"]MY PERSONAL current realisation (where I to build one) would look like this:1) S&B TX-102 as volume control, with suitable switch2) 2V Lithium Battery negative pole to the grid of the Valve, bypassed with good non-magnetic ...

Hi Romy,I think you may be struggling to get 10-12db of gain out of a spud amp (the term is a play on "one tuber").... May just about get it with 6C45.... remember you will be stepping down something like 12 to 18:1 on the OPT.best case: 10db require...

Go figure not stable are they. ...
