Yup. That is always the plan when I get a new radio.
morzh Wrote:2. unless you want a bit easier access to caps in RF chassis, no need to lift it, partly or in full. I only had a problem with one cap, but was able to deal with it.
Hmm, I'll have to take a look. I need to devise some kind of stand or something to work on this thing.
morzh Wrote:3. Resistors. Change on the basis of check results, in my case most did not need to be replaced.
I usually shot gun the resistors while I'm in there. I don't want to have to re-work these radios in 10 or 20 years again. And odds are the existing resistors aren't going to last for ever, even if they are in spec today.

Noted. I always have my phone next to me while working on radios, and try to take lots of pictures, but sometimes I get so involved, I start forgetting.
morzh Wrote:5. The dial hub might separate you could glue it back if the separation is not damaged apund. Otherwise repros are available. Mark Oppat is one.
I'm hoping the dial is still good all the way around. Mark's repro's are great. but he hasn't been able to find a supplier for the phenolic material for a while, and he's running out of a lot of his dials. Radio Daze quality is below his, but they do have a line on some supplier. I wish Mark could find out who their supplier is so he can get his back in stock.

The original 8uF filters were replaced with some other cans at some time in the life of the radio. Regardless, now that it's on my bench it won't see power again until I'm done working on it.
morzh Wrote:7. Check all tubes. Even if it plays.
As noted above, I ran them all through my 533A. It found 3 to be unknown or bad, but running them through my Weston 981-1 showed them above the reject point published by Weston. So they should be good. I tend to trust the Weston a little better than the Hickok, but the Hickok has far more tube data available, and is a little quicker to set up. So it's usually my primary tester.

Thanks. I was shocked at how well the finish held up. The bottom "legs" are showing wear, but the rest looks great.
