Hello to the group,

I recently picked up one of these.  With both rectifier tubes removed, the
unit still blows fuses.

There is clearly a dead short somewhere.  I have been over the wiring
several times and can not see a short.

The two VFO tube filiments illuminate ok, so that transformer is ok.

Next, I will disconnect all wires to the accessory plug to eliminate that
wiring.

I suspect that the main transformer has a short.  How can this transformer
be tested?  Is there an ohm value that is appropriate for the HV, LV, and
three filiment windings, or is there a way to power it separately to test
the various sections?

Thanks for any suggestions on transformer testing.

Sincerely,

Jim Temple
