Need Tubes

thefile, I have the same preamp. I have found that you can get well matched tubes with balanced triodes from Tube Depot (tubedepot.com) and they will save you 40% over the ones from ARC. Get the Electro-Harmonix over the Sovtek. You will appreciate the improved dynamics. Make sure you put 2 tube dampers on each tube and you'll be rockin' in no time.

I think that the same factory makes both EH and Sovtek tubes. I cant understand why you would put tube dampers on power tubes as these tube types are rarely microphonic. 

I agree with the Tube Depot, great site, good prices, quality products.   They have good, high temperature tube dampers on site, too.   They are low cost and it never hurts to squish microphonics in voltage gain stages, even tiny ones.

Upscale Audio or Viva, I have had nothing but good experiences with both.
