Tubes for BAT VK-D5


I would like to replace the orig. 6922s with a warmer sounding tube. Your tips and suggestions would be appreciated.

I used the amperex 7308's for a while. Now I am running NOS Russian 6922's--I think they're label 6h23's. Kevin Deal has them at Upscale Audio. I found mine on ebay, tested and matched for $10 @. They're much closer to the Amperex 7308's than the current Sovtek production. + they're affordable!

He has some lightly used stock that will do the trick.
