[QUOTE="Shinozoku, post: 89635, member: 1745"] Pull em out, put new ones in. No biasing required. The one closest to the guitar input is the input tube. I like a TAD 7025 or Tung Sol 12AX7 here. After that, is the FX loop buffer. This one doesn't matter too much, but a Tung Sol will work. The one closest to the power tubes is the phase inverter. This is the last gain stage processing the signal before the power section. I will ALWAYS recommend a nice NOS 5751 in there (Phillips, RCA, GE, etc.). Tung Sol will work though. [/QUOTE]
