it should work, US voltage isn't exactly 120 volts everywhere, there is a range.

Thanks ..........I was more concerned regarding the 50 Hz issue but I've powered up the unit and all is fine. Another newbie question though .....

 

The fine seller of this unit also included a collection of tubes for me to try including the following:

 

* The originals

* (4) RCA 6AS7G

* (4) Russian 6H13C

* (2) Philips 6SJ7WGT

 

So the story with me is I've been out of the high-end music scene for some time and have never owned a tube amp. I understand with this amp the pair of tubes nearest the front of the unit are the power tubes and the rear set are the drivers.  

 

I've tried the amp out with the stock tubes but before I start swapping these others in ........is there any danger in putting a perticular tube in the wrong location and blowing it up or is everyhtning that I have interchangable in any slot?

 

What would be a good arrangement to try based on what I have in hand?

 

There wasn't any manual included with the unit so I'm really shooting from the hip here and I thnk you guys for all the help.

I have the SE version.  But you should not be able to get one set mixed up from the other.  The pin-out should be greatly different.  You can play around all you want and then settle on the RCA's.

The 6SJ7, which are the driver tubes, must be in the back. Do not put them in the front, or very bad things will happen. The sockets are the same octal-base type as the 6AS7 power tubes, but do NOT mix these up. Power tubes in the front, driver tubes in the back.

Beyond that, no problem to swap the RCA 6AS7's for the Russian ones, but keep them in pairs of the same brand.

Mine's definitely a lot different then.  I have 9 pin and 8 pin in the SE version.

That's right - the SE used the 6BX6/EF80 for the driver tube, yes? Electrically equivalent to the 6SJ7, but as you pointed out, it's 9-pin.

Sorry to bump the thread, but i just got this baby.

 

Would like to check if the tubes needed for the amp need to be in matched pairs. (For both driver/power tubes)

If you were deaf in one ear, mismatched tubes could be used to good advantage perhaps...

I really want to get an LCD-2 but am a little worried that this is not the right amp for the job.

Can the DV337 power the LCD-2 or is this not a good match? Anyone tried them together?

I have the 339. It has enough power but I don't like the combination with the 339 that much.

The He-500 on the other matches great with the 339

Just thought I would point out the killer price I have on my 337SE in the For Sale thread....

Hi just a quick question hopefully someone will be able to answer it, how does the Darkvoice 337 sound with GE 6AS7GA and RCA 6SJ7GT tubes? Anyone heard this combination before?
