As can be seen from the #46 data sheet, the type is a "natural" for near Class "B2" operating conditions. That means MOSFET drivers between the splitter and "finals". The MOSFET drivers are pretty well settled. FWIW, my initial "guestimate" for #46 "idle" current is 7 mA. However, questions remain and I seek input from the "inmates". I'd appreciate recommendations for a winder of the 3.5 Kohm (end to end) PP O/P transformers. The "cast of characters" I know pretty darned well. I want good reasons for why I should prefer vendor "X" over vendor "Y". This amp will use GNFB and pooh/pooh remarks about NFB will be ignored. Another undecided area is the tube to use as the splitter. I'm debating between the 'T7 shown in the original EC or a 6J6. The 6J6 will definitely require a line stage with gain. That's not a problem, as I have good stuff already on hand and I also have a pretty kick butt 6SN7 design to use. Plenty of "dodads" will be in this amp's enclosure and getting source selection out of the picture could easily be the best choice.

I was wondering what to do with my 46s. Really good sounding tube. |
