42-400 Code 121
#3

> Does anyone have any idea if any other models might have a speaker that would be correct?
I would try one from a 41-295/41-300. Opt is mounted to the chassis so the field coil and voice coil are the only consideration. The fc resistance isn't particularly critical as it's not uses to develop bias voltage, but only filters the + hv.

You bet. Full of rubber wire and a somewhat tricky FM circuit to get working properly.

> This one is probably not very common.
Abt 5000 made. That not a lot but every once in a while I manage to find < 1000 produced set.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

No, it's not a problem, just during certain condition it could show up. Yes, an internal tube short could do that too. ...morzh — 09:13 AM
