[Hallicrafters] SX-25 sn/H-104930

[DJ]

Hi all,


So after almost 5 years after acquiring an SX-25 and promptly putting it on a shelf to wait for that rainy day yesterday became that rainy day. I decided to start the overhaul with a full recapping of which I finished most of today.

Having "restored" an SX-16, S-22, SX-42, SX-62 and a few others I feel pretty confident I can handle this one too, but having said that all it really means is that I can follow direction and know a little bit about radios...

So my questions to any of you that have gone down the SX-25 road are now that it's on the "bench" are:

A. What are the standard improvements if any?
B. Is there any good reason why there is a 6AC7 AND several 6SG7 tubes being used instead of the 6SK7s?
C. There are two wrapped wires twisted together, but not joined between the set of pads for the OSCILLATOR and for the 2nd IF.  Is this normal?

There are a few other things, but I'll start with these.


Best Regards,
Douglas
