Hello everyone, have had the 339i for a bit now and have gotten used to the stock tubes; which to me sound good. Any recommendations for best tubes for this amp? I'm pairing them with a HD6XX for context.

Years of production experience feels like a good match.

Are you saying you can use an L63/6J5 tube as a driver in place of 6SJ7/5693?
That does not seem right.

It would be for the L63 driver version of the amp different from the 6SJ7

The HD6XX would definitely enjoy a slightly more forward tube combination- some power tubes to consider are Tung Sol 6080, 6AS7, 5998 or 7236. Drivers try the EF86 or EF80 with adapter

Unfortunately some of the better power tubes are unobtainable these days. GEC 6AS7 is my favourite in this amp as mentioned by the amp designer above, but one went yesterday on auction for $450AUD..

A pair of GEC CV4079 with adapters can get very close to the sound of the GEC 6as7g for a fraction of the price as there are many available for sale.

Hi guys, I’ve been really enjoying the 339i what a great amp, I decided to try the pre outs into a few different ss Amps with my he-500’s but I’m getting a loud buzzing from the pre outs, I’ve changed power cables/power sockets ect and s also different sources, any thoughts on what it might be, it’s completely fine as a headphone amp, I’m still using the original power tubes
Cheers Marty

What kind of adapter would I need?

But isn't the gev cv4079 a driver tube and the gec 6as7g a power tube?

I have a Darkvoice. In this amplifier, the GEC CV4079 is used as power. At La Figaro I know that some people also use it as a power. I had never heard anyone say that they used the GEC CV4079 as a driver.

The Adapter is the one from the link below:

CV4079 is equivalent to half a 6AS7, so a pair with adapter is a suitable replacement

Thanks Boss for your recommandation and I agree, I enjoyed that combo to death! But I am still enjoying Telefunken 6080 and EF86 too! Different flavour for different style of music ^^

Thinking about a new DAC in the near future for my 339i.

1. How much DAC is needed, ie is it overkill to buy a costly one if the amp is smooth sounding?

2. There is a bewildering choice out there, both in DAC design and features, it's certainly a rabbit hole!

GEC 6AS7 is top of the price, Next Western Electric 421A, Tungsol 5998, 2399, 6520, 6AS7, 6080WB Ceramic plate. But my favorite is Tungsol 5998, Regards, Kim

Wow, nice collection You have out there
As for the tubes it all depends what one would like to achieve. I used to like RCA 6as7G (warm power tubes) with Tung Sol 6sj7 mesh driver tubes.

La Figaro, despite its price, is absolutely top sounding amp and benefits from a good DAC. I paired it with MHDT Orchid dac and got really smooth analog sound. It is good for jazz and instrumental music. For other genres You may want to look for something more neutral. La Figaro will reflect the quality of a DAC for sure.

I have the Soekris 1421 R2R DAC - LF339i scales well with decent upstream gear.
