There are 3 schematics on the page.
http://www.nostalgiaair.org/PagesByModel/795/M0029795.pdf
The first one uses a 24 and 27 tube. These are 5 pin tubes.
The second one uses a 57 and 56. The 57 has 6 pins, 56 has 5 pins.
The third schematic uses a #32 and #30 tube. These are both 4 pin.

:I cannot seem to see what the two tubes are from the schematic that is listed here. Can anyone tell me what they might be? I wanted to buy this little converter, but not if I will not be able to get the tubes, especially if they are very expensive. Thanks for looking.
