It is kind of unbelievable in away: I have for a week the same stable sound. That is a good sign. The less good sign that I need to do something else in order to take sound where I would like it to be.
Without doing anything I like what I am gettin...

Experimenting with the new 2A3 tubes has been a very interesting experience. It has given me insight into more specifically exactly what I am looking for in the stereo sounds, which I associate with the Sound.

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

[quote user="Romy the Cat"]
For instance the 2A3 has no tungsten cathodes and therefore its cathode might be “poisoned” in time if it was not properly pre-burned and some other methods were not taken care. Those methods are expensive but they ...

With regards to the links, as it happens, I totally agree that 15in Tannoy Reds struggle to handle complex music. The crossover is too simplistic and the cones too hard to control with a low power amp. Reds can be lovely in a simple vintage system bu...

Thanks, floobydust.
There are a lot of interesting points in you post to consider. What speaker you drive with your 2A3? If they are relatively high sensitively (like compression drivers) then did you consider going with a single stage? I think I ha...

[quote user="Paul S"] I think that bit of marketing hype must derive from Lamm's ML2 (& 2.1?) "Operating Manual", which says: [the ML2] "Maximum Output Voltage" "with continuous sine waves, at 1kHz @ rated line voltage" [is] "(blah, blah, blah), ...

Adrian,
Are any of those new tubes besides the Chinese tubes are single plated? I have bought some very nice 2A3 and 6A3 double plated from 1942 and 1944 and it will give me an ability to see what is going on with vintage tubes.
I was not ...
