Scott 16A
#1

While waiting for some re-chroming to get done on my Scott 16 (1937),  I decided to tackle this Scott 16A (1947).  A much newer radio than I've handled so far and has FM.  I have the AM aligned and sort of the FM.  Never done an FM alignment before so I still need to do a bit of work.  Seems even the presence of and the movement of my body near the chassis affects meter readings when aligning the  final FM stage that is part of the discriminator.  I'd like to try the FM alignment using my O-scope but need to do a little research on that yet.  FM sounds great, though.  The speaker is not original to the radio but is close.  It is a 15" Jensen coaxial that seems to give some fairly clean highs.  I need to build a cabinet for it so that I can get some lows out of it.

Stuffed all of the tubular caps and the electrolytics.  Had to replace several resistors.  They are all the more modern molded carbon type.  Several 1/2 watt resistors of 220K and 330k values were open.  I decided to change all of those values since it seemed to be a common theme.  Most of the other resistors were well within spec so I left them.

There are a lot of Tobe and Sangamo molded caps that look like Mica's.  Not sure that all of them are.  anyone know about these brands of Mica lookalikes?  Any info would be good.  I would rather not replace all of them if they are a good cap, as there are quite a few of them in this radio.  Except for the "Music Control", which is some sort of noise reducing circuit,  the radio is working great.

this radio will be a shelf queen in my shop area and will provide entertainment when AM just gets too noisy to endure. FM will be nice.
