After a night of drying the Deoxit I turned it on today.
It was scratchy and rumbly as heck.
I touched the tubes....heard the sounds. Took he tubes out and scraped the contacts.
It seemed at the time as if that did the job: I tuned into my local station at the usual tuning cap position and it sounded fine. Not that I am very impressed with the speaker out of the cabinet but then it is just that, out of the cabinet.

Then I switched into FM, SW and back and the rumbling and scratch returned only to disappear after exercising the switches. SO maybe they need some more exercise.

Now, the speaker cone has a bit of crack in it, not even sure how something like this can appear, but I took care of it with a but of rubber cement.

Two questions:

1. Here is the pic of the speaker.
What do those patches of thermal insulation doing there between the cone and the basket? Are those by design or did someone try to remedy something?
   

2. One pilot light bulb is burnt. It says GE 54 (if here is anything else I cannot tell). The other bulb is OK and it says GE 1445.
I put in type 47 (I think) - it has the same bayonet base, and it works fine; I am sure these supposed to be 6.3V. The 1445 is very dim. I suspect it is not 6.3V. It looks exactly as the burnt one.

   


Does anyone know what bulbs were there originally? Cannot find in the BOM.
