    I have a Model 325 and need to know what tubes it takes . It has 5 sockets 1st. af. 2nd. af 1st. rf. 2nd. rf and det. It has no tubes in it. I would like to know what I need and where it goes.
    Thanks for help

    Looking at the schematic I would say that it takes 01A tubes in all positions. Since it does not use a separate B+ of 22 volts for the detector then an 01A would be used there.

    Thanks Ed
    I will have to see if I can fine some. I am not in a hurry as I don’t have a power supply to run it on .
