Pulled out my 37-650 tonight
#22

Update on the 37-650 Restoration:

I finally took out the Broadcast Band antenna coil and
it turns out that the messed up coil was the primary winding
which only had about 30 turns of wire on it. The secondary
was all good (had hundreds of turns).

I used some #32 magnet wire and got it all re-wound, and put back.
I now get MUCH better reception on the broadcast band!

Also, I read up on the shadow meter and discovered that one can slide the coil forwards or backwards to set the shadow offset. (I have the "New style" shadow meter).

So, I tweeked that and now the shadow meter is working much much better also.

Final step is to order a set of rubber bushings for the RF chassis and I think that will about do it for the electronic restoration.

Now to tackle that horrible cabinet!
