1st detector winding
#5

Hi Tim,

Pardon my manners it was kinda late last post. The 1st gen 90's (p/p 45's) and the 2nd (se 47) use the same rf plate coil. The 3rd gen (p/p 47's) has a different IF frequency so I would think some of the rf parts are going to be different. Probably not the rf amp coil.

When you have the tuning cap out to replace the grommets under it do take the screws that fasten the stator plates in place loosen one by one and re-tighten one by one. My set had an intermittent problem where the volume would drop down abt 1/2 after a hour of use. 10 or 15 mins later it would resume at full volume. Very annoying. That was the fix.

figure out what all those squiggly meant.

Now I think I've got!
