The 40-190 is supposed to be an 8 tuber, what difference that makes to the performance is another question, It looks like they added a 7A6 dual diode but both diodes are tied together, the schematic for how that tube is connected is somewhat confusing. I can't really see the point of it, it seems like tube stuffing, if they wanted to add another tube why not add another triode to act as a phase inverter and make the 41s into a true push pull power amp? I've seen this sort of scam go on with other sets like Canadian and American G.Es and RCAs, add a 6H6 and use a 6F5 rather then a 6Q7, they add a redundant tube that they don't need just to make it a 6 tube set. I agree that the price was a little high for the condition but at least it's complete, and unlike a 40-180 they don't show up every day, maybe every other day or week, but not every day.
