For sale is a good tested set of 5 vacuum tubes (not all shown):
6SA7 6SK7 6SQ7(or 6SQ7GT) and 5Y3GT
and 6L6GC / 6n3c (maybe be good but broken guide pin, and arrow on tube showing where guide pin was)
ask if you want a different rectifier like 0Z4 5W4 6X5 etc.
the first 3 tubes listed might be metal or glass i.e. 6SQ7 or 6SQ7GT depending what we have
