Model 20 output trans "surgery", and questions.
#3

Thanks Chuck,

"notice you said that the top half of the winding was "open", but your note on the schematic says "0" ohms!! Not the same thing obviously!! Zero ohms is a SHORT, not an OPEN which is infinite ohms... "

OMG thanks for pointing that "Brain Fade" moment out to me Chuck Icon_smile


The trans itself looked pretty good, and the insulation was not flaking or I didn't see any corrosion spots inside. The 'mess' you see was where I had 'picked' the layers carefully with an Exacto knife.

The set looked very good otherwise, no rust or anything like that other than a lot of dust bunnies. I will need a new dial though as this one's seperated. Looks like two scales on top of each other. Mike at Radio Daze has them.

I will probably go with the electrolytics to ease the turn on surge of the set. I assume they will be the 450 volt rating?

Understand what you say about the construction on the older caps and their physical size.
Thanks again Chuck.
Gary.
