As stated: the WGTAs can be replaced by GTs/VT-231s/Ws without fear of mis-match. The on-line/mail-order tube vendors that I researched generally are sold out of the tubes that I've recommended, or- VERY proud of them. Upscale Audio has Ken-Rad at a reasonable price(and he tests his tubes for noise-VERY important in a pre-amp). I've had good experiences with purchasing tubes on eBay. Just stick with the sellers that have high feedback ratings, and list the test results for both sections of the tube. If you are trying to warm things up: Check with Kevin at Upscale, and see if he's got any NOS Brimars or Mullards in a 6SN7. He's got a keen ear, and can tell you what tubes will give you the sound you're trying to achieve. Did you look at the tube comparison site that I included earlier?
