I have the Tubefex and am looking for spares. I did all the mods and also tweaked the preamp board. I modified both Classic 50 212 with a tube power board I designed. It has high voltage standoff, individual tube bias,modified fan circuits and quieter fans, extensive attention to wire routing where it can benefit. The Tubefex is a great find if working and not at all underrated. Through time and after many configurations I have the Tubefex cabled as follows.
Guitar to Tubefex input
Tubefexmain out to Classic 50 effects in
Tubefexeffects out to Classic 50 Instrument in
Classic 50 effects out to Tubefex effects in.
It's like a preamp Swiss army knife.
So I can bring in the Classic 50 tweaked preamp through the Tubefex efx loop or just leave them out as I mostly do. It is addictive.
