It’s also down to the circuit they’re in. Some circuits they’ll be a lot less micro, some there won’t be any.

Micro tubes can also be fine for tube DACs.

Seller just refunded $100 (50%) on those triple mica, so I’m happy with that.

What criteria are you guys using to decide if a tube is microphonic or not? I've been lead to believe that it's not a good idea to tap on them to check for microphonics.

Infrequent very gentle tapping is ok, but too much and you’ll make a good tube micro.

What I’d call a microphonic tube though is where it will amplify knocks on the amp or desk considerably.

As with most things, you should only do this with the proper tool, and NOS versions seem to work better.

100% agree, when they are that bad I usually chuck them out except for my 59 6201 PW pair and my single 55 ECC81 Heerlen. Though I am on the lookout for a 55 replacement tube.

Foton and Reflekton 6n3p late 50s triple micas arrived today.

After testing for shorts and basic gm measurement, I have 9 pairs and a single. I think the single and 4 pairs are sold, leaving 5 pairs left (2 of those might be pending a sale) if anyone wants a pair?

Update: 2 pairs and a single left.

Hm think that I will grab that and then I’ll have a pair of square getter and a pair of horseshoe getter. Not sure there’s any real difference but what am I going to do with a third one anyway if not pair it up?

So, to clear this up for probably the 1000th time, if the Lyr 2 manual says "sure, go ahead and roll in 6N1P", I can do it right? I saw oldder threads where people were like "nooooodont". But the manual....just asking cause they are damn cheap and don't need adapters. They sound pretty good on the HE400I with my Vali 2 (my Lyr 2 is on the way).

Lyr 2 manual says:

Lyr 2 accomodates any 6DJ8, 6922, ECC88, 6N23P, 6BZ7, and 6N1P tube types, so feel free to swap the stock tubes to “tune” the overall sound signature to your needs.

But that's a bit confusing, because the Lyr 2 has a heater current max of 415ma. The 6n1p heater current is 600ma.

Then again, they misspelled accommodates, so who knows...

Yeah, exactly. How's a brother supposed to comprehend that one??!

Besides occasioanlly shrill/a tad siblant highs, I really think the 6N1P-EV I got from VivaTubes sounds awesome. It is really responsive and pretty detailed. Shame I can't pick up a $30 pair for my Lyr from Viva and not worry about it damaging an amp I can't afford to replace.

A $30 pair of Foton triple mica 6n3p will sound much better to be fair.
