Darkvoice 336i & 336SE Tuberolling PartII - Page 16

Hey DV336ers,

Happy to have just gotten a DV336se from a fellow head-fier. The sad thing is that FedEx dropped the box (which broke a 6AS7), and now, unbelievably, the right channel is dead and buzzing. I want to rule out a bad 6AS7 as the source of the dead channel problem, but given that one has been broken I've got only one remaining. (I've already tried two different 6SN7's, so swapping input tubes does not affect the problem.)

I'm hoping that one of you with a big collection of DV336 output tubes might be willing to spare a crappy sounding but working tube and mail it to me. I'd happily pay you via paypal for postage and your time and something, of course, for the crappy sounding but working tube. Let me know.

Best,

cws5

Hi, I am a new 336C owner here. I have been using a LD MKIII for a couple years and I must say the Figaro does sound fuller.

When I first powered on there was some hum. After couple of hours the hum went away. So I guess there is no need to do the FITZ mod immediately if you encounter hum issue with new tubes. It might go away.

I put on a Sylvania 6SB7GTB and it sounds better. I am getting a RCA black plate and will try it soon.

Hi,

Which power tubes are better ? 6080/6AS7 or 6AS7G ?

Im going to buy RCA 6080WC or Sylvania 6080WB or RCA 6AS7G or 6AS7GA General Electronic. I cant decide which one should i buy.

RCA 6AS7G. That's my pick. An obvious one.

I'm going to buy the 336SE very soon but i'm also interested in changing the tubes to something better but don't want to spend too much money figuring out which one is the best combo.

So can people tell me what tube combo they found best with the 336SE?

Thanks a lot in advance.

Just bought the Darkvoice 336SE tube amp :D

Looking around for some 6AS7/6080 tubes as i just realised my dad actually has a large collection of 6SN7 tubes for this Leak tube amp. I'll also be changing the coupling to paper oil caps later.

I liked the Tung Sol 5998 in the rear with the RCA grey glass 6SN7 in front (or Sylvania Bad Boy).  Sold the amp ages ago for my maxed WA6, which is a good step up, but the 336i was still pretty darn good for the price.

 6AS7, 6080, 5998, ECC32 etc can all be used on the back socket but does it require any changes on the circuit?

I did just order a GEC 2523 should do mighty fine in the 336. I sold the 336se but my woo3+modified uses the same power tube.

ECC32 won't do, otherwise no changes required. Also 6520, ECC230, 6N13S, 421A, ...

Please don't drop the CV part. GEC CV2523 = GEC A1834 = GEC 6AS7G.

Thanks for that Oskari. Just a curious question which tube model for the rectifier tube did you find best?

I'm a big fan of RCA and GEC 6AS7Gs.

BTW, it's not a rectifier. It's the power output tube (in this amp).

oops, most peeps I hang with just use the numbers. Forgot where I was at.........

Received my 336SE today but the tubes that were provided had rust in them and only 1 channel worked :( So now i have to wait for my 6as7 tubes to arrive.

Will ask the seller to give me a partial refund or replace the tubes. Not sure which one at this stage but most likely partial refund.

Unrelated to tubes but related to 336SE.

Does anyone know what the ratings are for the coupling caps?

I want to change from 6 to 2 paper oil cap but i'm not sure what the voltage and uF is on the red caps.
