4P1L Pentode Driver (Test 2)

From what I gather from Fred and some others, there is likely a significant to major decline in tube life using the D on the wrong setting, but given uncertainty over the 4p1l pentode circuit in the Lampi, it's hard to say how much.

Additionally, I was using a Brimar rectifier from Langrex in 4p1l pentode above, and in our auditions Saturday. It 4p1l pentode a cleaner sounding rectifier, which would have the effect of making the D sound even thinner. So, if I had to live with the D, I would want a warmer rectifier like the Brimar, and likely also run the D on the wrong B setting.

That's the only way the tonal balance sounds right to my ears on my system. But in switching to the 45 tubes, it's evident the Brimar is adding warmth in the form of distortion, and the Lampi 4p1l pentode is cleaner and more resolving rectifier that mates well with these high end 45 tubes.

Indeed, the system sounded better last night than over the weekend. Ok, 4p1l pentode for the digression, that I realize is somewhat off-topic - this thread being about Atlantic.

I have not used the SMs before on the GG. This comment is pretty useless as I have not been using the system for a couple weeks, but the Atlantic with Soviet 5c3 recti did strike me as a bit more SS in 4p1l pentode the 4p1l pentode were extended and crisp, but still retained the traditional Lampi midrange lushness.

I think 4p1l pentode may be a supreme bargain from Lampi and a great intro to their Dac range Very preliminary, so take with a grain of salt. This comment is pretty useless as I have not been using the system for a couple weeks, 4p1l pentode the Atlantic with Soviet 5c3 recti did strike me as a bit more SS in that the highs were extended and crip, but still retained the midrange lushness.


I loved 4p1l pentode car analogy write-up! I wouldn't use those Shun Mooks. They are over 20 years old, and no marks on them for pointing which the current ones haveand that affects sound adversely if placed the wrong way. Norman, just wondering.

The case weighs little comparatively, its the BIG iron underneath Hi, This is an integrated amp. No pre -amp needed.


It uses the same tubes as the DHT pre. I can get the odd 30 minute here and there and every time I try to get upstairs to the workshop something pops up.
