Just got myself a 336se. Should be here next week. I previously had a Little Dot MKii which I foolishly sold off despite having collected some very nice tubes for and I've been missing it for my 6xx. Instead of rebuying I decided to try something different.

I've already won auctions for a red label RCA 6AS7G and an RCA 6NS7 grey ladder to get started.

Any recommendations for some "must try" tubes for this guy? I'm wondering if there equivalents to some of the "must trys" for the LDmkii (Voshkod EV, GE Jan 5654, Mullard 8100, etc).


Any advice to first time owner would be much appreciated.
You got a library of info in this thread, you'd be surprised what 15 minutes of reading will do for you.

Anybody else here have the Mullard 6080, wondering if these tubes need longer than average burn in. As of now, I'm not that impressed with the great Mullard 6080 as many have raved about it. I have a $14 Philips/Sylvania JAN 6080WC that has better sound than the Mullard. Better instrument separation, better vocals, and clearly better bass. I went to the 6AS7G thread and was told that high dollar tubes dont really mean anything if they don't play well with your amp.. O.o So the Mullard plays well on most amps except the Darkvoice? Anyway, I'm just venting, hopefully some extended burn in does something to reveal a good sounding tube.

Can you share the CODE on your tube?

These little 9 pin tubes sounds really good, old acquaintance dropped a bunch of them at my worksite and said have at it, take what you want, so far just the 12AU7 , have a few others but not sure if they are compatible.Have a 6GU7,Raytheon12AT7WA, 6BK7,6GH8A, I'm hesitant to try them.. Dont want to fry the Darkness.. :D

These go dirt cheap on Ebay, $3-7 and I'm told sound just as good as the 6SN7 variants. Found the adapter on Ebay as well. I found the 12AU7 listed as compatible to the 6SN7 so did not hesitate to warm her up.

List of compatible tubes:
6CG7 12AU7 6N7G 6N7W ECC31 7N7 6A6
6N8S CV181 ECC32 5792 6F8G
Too my knowledge guys, dont hold me accountable. :)

EDIT: Well I just tried the Raytheon 12AT7WA, wow....I am surprised.. a lot fuller, and DEEPEST BASS yet experienced with the Darkvoice HD6XX combo..this one I would add to my highly recommended list.

A couple of questions:

Where did you purchase the adapters?
Does this eliminate the hum that can be associated with 6sn7 tubes?

Well first things first, there is hum on NEW tubes, no matter what they are, on some, not all, depending on manufacturer. And the adapter, as mentioned in the post, EBay.

I guess I've only used NOS tubes - I've had to resolve the hum with all that I've tried.

Easy fix, pull out 6AS7 tube, power on Darkvoice with just the 6SN7 tube in. Come back 48 hours later, turn off, plug 6AS7 tube back in, turn Darkvoice on. Hum will be gone. Burn in is key.

I've done that with all of my tubes but I think it is a PITA and I'd rather not. I have not brought myself to do the "Fitz" mod either.

Funny to hear tube rolling as PITA
The rolling part is fine - I don't particularly like tying up my amp for 48 hours to get rid of hum. My other headphone rig doesn't require the run in so rolling is quick.
