You don’t see many of these radios around. If you still need the 6A7 and 6D6 you could try Mario (The Tube Man) Fantetti at email timarfran at sympatico dot ca (I’m not sure if an actual email address is permitted here). Don’t know where you live but Mario is in the Toronto area. If you have trouble finding a 6D6, a 78 is a good substitute.
