Re: Another Berning EA-230 tube question

Fishfood, hi. 12AT7 NOS are plentiful and not expensive. I think most of the EA-230 I have seen had Yugo (E Europe) 12AT7 tubes in them - heater flash and all. You could put in 6201. Like I mentioned before - the 6SN7 is specified as 6SN7GTB. It has to be the GTB version (higher dissipation). The output tubes (6JN6) are being run as conservatively as possible in Class B where there is minimal current in the tube during no-signal conditions. Do the 12AT7 need to be matched? It wouldn't hurt. Is it really necessary? Probably not. If this is an initial foray into "tube world" I would recommend learning as much as possible about how tubes operate and the characteristics of the tubes in your amp. I always recommend learning from the schematic as well. This kind of knowledge has a good effect on jitters which may be partially caused by not knowing.
