just ordered the Brimar 6SN7GT. it cant be that bad compared to the stock one i have which is

pic stolen from the net but is identical to the one i have.

I hope the pins on yours are cleaner than that one. Such atrocities should be considered a death penalty offense.

True, but I suspect the new production Brimars are closer to EH than Foton or Melz.

Entirely possible, but if they are truly using Brimars designs and tooling, they could be pretty decent. I'll probably have to try one whenever they become available to us US-ians.

i think once Brimar are up and running with their machinery and enthusiasts things might get better. they seem keen. price was ok for a new not old stock tube, only £4 postage.

TBH i CBA playing Russian roulette. if the brimar sounds good i'll stock up. how long do tubes last on average?

 

[Ripper2860]

I don't think they are using the Brimar design. Different plates, getter holder and spacers. Unlike any NOS Brimar I've ever seen, but who knows -- the may be totally AWESOME!!

The general consensus on lifetime for 6SN7GT seems to be about 5,000 hours.

best turn it off when not in use then. or it will be a tube a year.

 

[Ripper2860]

My rule of thumb is if it will go an hour w/o listening, I turn it off. If I'm stepping away and will be back to listening in an hour or less, I leave it on. Repeated power cycles for short sessions can be more stress on a tube than just leaving it on for a bit.

would this be the correct pinout for an adaptor?

Yup. Perfect.

Santa stopped by early and dropped off a pair of Drop/Hifiman HE4XXs. Sounds great with the Vali 2 and new Tung-Sol 6sn7GTB. Completely different SQ from the HD6XXs I'm used to. Much more detailed highs, imaging is better because of it. More space around instruments. Really deep, but not overpowering bass. Takes getting used to.

 

[Ripper2860]

Congrats and enjoy. I'm a huge fan of Hifiman's sound profile.

I'd recommend giving 12au7s a try with the 4xx. My 400i loves them… huge soundstage that works so well with ambienty type music

You're right! Gonna roll through my little collection. Thanks for the tip.

Just tried my secret weapon, the 12ax7 EH. Is it sacreligious to say I like this combination (HE4XX / Vali 2 / 12ax7 EH) better than the HD6XX / DarkVoice / 6sn7?

Nope. Not at all!!
