How to select non-noisy tubes?
My FM Philharmonic is getting noisy. All tubes test good and non-microphonic. I have a stash of replacement tubes and I wonder what is the best strategy for selecting "quiet" tubes. The audio section seems to be OK so the noise may originate from RF section. Specifically, I wonder where to start replacing, what tube maker or tube tester results should I use, and whether there is some kind of a rig I could make to test tubes for noise out of the radio. Thanks, JiriSee More

OK folks, since many of us are stuck at home - what Scott projects are you working on? We've seen a lot from Rob, he's keeping busy! I have started to scan all the correspondence I have...many hundreds of pages of letters to and from Scott Labs. So...in the Scott Info Archive, I have added a folder "Correspondence". I've put one neat story out there. As I get more scanned, I'll add them. I'm hoping to make the files searchable, so we can find key words and such in all the documents. If you all…See More

Question for anyone with AW15 restoration experience.
Have a nice 15 (late) and had the radio working and tuning the broadcast band until the band switch started to loosen.
The set screw on the collar just before the shaft enters the gear box became loose. (Don’t touch anything if this happens to you!)
Needless to say, exact position for the turret, the antenna contact points eccentric cam…
