Two good places to get an affordable set of tubes are Antique Electronic Supply and Vacuum Tubes Radio Tubes - 5,000 different tubes in stock - Over 10 million tubes! - reasonable prices, and you can get NOS tubes that will definitely outperform the stock tubes for not too much money.

OK, got my 336SE yesterday. Ordered on Wed. afternoon, received East Coast USA on Mon. Damn. 1st impressions, good build quality, feels solid. Dead silent, no hum. The sound has gotten progressively better, but still not what I was hoping for. I can't wait till I get some additional tubes to roll. Any advise on tube combos for Grado 325s?
Thanks

Congratulations on the new acquisition!
There is a night and day difference that you will notice after you get some decent tubes for this unit (if u havent already).
Skylab is more versed in giving the appropriate tube advise.

For Grados go with a 5998 for sure as the power tube - it will handle lower impedance cans better.

The 336classic is better.
This edition of the 336 sees the case being streamlined. The case is now slightly less tall and features a very stylish chrome reflection plate. This beautiful chrome feature really highlights and reflects the warm glow of the tubes.

The beauty of the 336 Classic is more than skin deep. The slightly revised circuitry and new ASC film capacitors really do offer a slight increase in sonic resolution compared to previous 336 editions.

This version also does away with the front toggle type power switch in favor of a much more discrete power switch on the rear panel.

Build quality is absolutely first rate. Each amplifier is hand built and tested.

Using Point to point wiring, the signal path is kept as clean as possible.

High quality components are used throughout.

Really suits Sennheiser HD600, HD650 and other high impendance headphones.

Also suits AKG headphones very well..

See my EF1 review (link is in my public profile "about me" where I talk about synergy with headphones and how the EF1 compares with the DV336i and upgraded tubes.

I did think the 336i was slightly better with HD600, but the EF1 was better with everything else with a lower impedance yet still very decent with the HD600. I only compared the EF1 and EF2 with my HD600 and thought they sounded very similar, and I am happy with the EF2 even though the EF1 and 336i are gone.

Hey folks, I just got my new 336Classic delivered today via DHL, and have it fired up. It is driving my K701s. It looks pretty darn cool!

I rolled in a T-S 5998 and a brown-base Syl 5692 and things are sounding quite nice, and that's with only a few hours on the amp. Sure it needs to open up some, and smooth out a bit, but this thing is really driving the K701s nicely. It had some hum, but after a half hour or so, the hum disappeared (with the 5692, that is). No hum with the stock tubes. This unit is very quiet too.

How much time have you been seeing for the 336 amp to completely break-in?

I'm anticipating good things ahead as it breaks in!

Thanks to all who thought highly of this amp, and the suggestions for tubes!

Anyone have issues with RCA VT-231 grey glass humming in their 336?

I did, but after I put 15-20 hours on the tube, like most others, it got quiet.

I'm going on memory here, but that one took a long time for the hum to go away. I'm thinking 30 plus hours to be completely silent.

Ahh ok, thanks for the replies, will keep them burning longer
