This is a PYE P35 manufactured for England and the European continent. It runs on 210 to 250 VAC and needs a step up transformer here in the states. After restoration this radio is rather sensitive. Bands start at 2000 meters (150 KHz) Long Wave (LW) and goes up through 18 MHz.
Interestingly the Mid Wave (MW) band and the low end of the "Trawler" (as refered to in the alignment procedure) MSW band cover the US broadcast band. The LW and MW band is labeled in meters so one must do a conversion from frequency to meters when locating a station.
Wavelength (or Lambda) in meters = 300,000 / f (frequency in KHz.)
300,000 / 1020 KHZ (KDKA Pittsburgh)
294 meters on the MW dial scale
The challenge with this chassis was the broken oscillator coils. Two were out of their metal retainers. I suspect the plastic has shrunken over time and shipping broke loose the fine hair like wires. The antenna coils were loose also. So after some delicate soldering, with no coffee, the coils were repaired.
Pitch or tar was used to secure the aluminum and pressed iron powdered tuning slugs from detuning from vibration. That was a point of focus. A heat gun was used to soften the pitch and several alignment tools were employed from plastic, fiberglass to carved wood to perfect the alignment.
Once the radio was fully restored and aligned it received well on an external antenna. There is no internal antenna so a long wire antenna is a MUST for strong Long wave Broadcast and Shortwave reception. (If you live near broadcast stations then a few feet of antenna wire on the floor may be all you need. But you will need some lenth of wire.) A suitable ground may also be needed.
Unfortunately, I do not know a source for the British pins that plug into the antenna, ground, speaker and PU receptacles. I used snugly fitting (slightly zig zag bent) stubs of solid copper house wire. I will be keeping my eyes open for a properly fitting pin jack. I suppose one could have them fabricated from Hobby Shop brass tubing or rods.
The copper wire stubs worked well for the PU or Phono Pickup connection. Keep in mind this is near a line level input looking for a crystal or ceramic phono pick-up. I connected a CD player into the PU connections using an old headphone cable and alligator clips. Connect both Left and Right to the upper PU connector. The Shield goes to the lower connector (gnd).

This cabinet is to be refinished.
One challenge is to reproduce the logo decal on the top of the cabinet. I could not find a vendor that supplies British logos.
