I pick up a Varmint xl 350 from a friend of mine the other day. He told me it was in working order but the tubes might be alittle soft because he hasen't use it in years. When I checked it out it has 1 6kv6a tube driving 2 6je6c tubes. I had many amps in the past but never a Varmint. I thought the varmints used 6LF6 tubes? The only reason I'm asking is because I have about 8 good 6LF6s in my tube collection. Thanks guys Joey 2AT054
