The PHILCO Phorum

I have 2 working Philco 70s on my bench. The one has a later looking repair on the first detector transformer (part #6). There's a 150K resistor across the primary and a .02 cap across the primary and secondary. Was this a quick fix for a bad transformer?

Sounds like it. Measure the resistance of the coil.

You mean disconnect one side of that 150K resistor and measure the primary, right? It measures 14 ohms on the other 70. Let's say it is indeed open, what then?

It's open. I sent Ron a coil rewind request.
