oh and its got a real funky degausser circuit. Its manual (push button on rear of set). Does not seem to work.
whats odd is on my later PB the circuit makes use of line AC in series with the coil, and a charging circuit for a large electrolytic cap. pushing the button starts the charging process which draws AC thru the degaussing coil. As the cap charges up, the current thru the system drops. releasing the button cuts off the now minimal current flow (fully charged cap) and also starts to discharge the cap thru a resistor. I guess you could mess it up if you just popped the push button very quickly (did not allow the cap to fully charge) but it only take a couple seconds. Now that is the later version. this set is different.
it uses a large NP cap about 4uf and B+ (410 right off the doubler) and a couple resistors and a single diode (the later one described above had a full wave bridge). I cant for the life of me see how it would generate an AC thru the coil (the 410 is before the choke so it has some ripple on it but not much.
and it does not seem to work (press the button and you can hear a tiny bit of coil noise, but it does nothing to the pic.
