I found some time today to get started on another restoration. I looked at the 70, but it's missing a coil and the speaker is ruined, so I wanted to get some more practice on something easier first.

I've started on the 87. The underside of the chassis is immaculate, I don't think it has ever been messed with, I want it to look that way when I'm done. So far the ww resistor, coils and chokes ohm correctly, and I've tested about half the power transformer's windings.

The audio phase inverting transformer measures 2.5k on one leg of the secondary, and 70k on the other. I'm sure that isn't right, what options do I have for fixing or replacing it?

Also, the power switch is broken. I think it uses the same sort of switch on the 70, looks like layered wafers. Does anyone have one they could sell?


Thanks!
Will
