Ok, I took the cover off, there are no tubes inside this unit at all. As for numbers, if it was there, they are gone. This radio has been sitting around for ever in a garage, so hard to say what happened to the numbers. Numbers that I see inside this unit are TFD6000A, TLD6812A-5, TLN8387A, and then the one Stamped on the Top TGN6002A. Inside the PA aera, there are two transistors that feed to the bottom for the heatsink. Can't see any numbers on them. Several tunning pots, and coils. The control head, I am told said Motran on it. Tis all that I know about it. Thanks.
