It's an export model for Australasia I think, it's a mains set with mains valves and probably a vibrator pack to run off a a car battery.

that sounds great
i am in new zealand so it sounds like you are correct in export model and that would explain the "E" in the model mumber PE 77 E for export???. ima new enthusiast as i grew up with the valve sound and found this set im keen to get details on how to use it etc. i thank you for your assistance and let me know what else you would require to create a model page.

Because of the Vibrator pack and Extra SW no LW the model is definitely export type hence no service info. But circuit is a combination of P76 and PE59CR (without extra RF Preamp). The Finned thing is a Metal Rectifier instead of EZ41 or EZ42 to save power. The EL42 is also lower power than EL41 to save 6V car battery (today Car batteries are all 12V, but they used to be 6V in 1930s to 1950s).

The capacitor between EBC41 anode and EL42 grid needs replaced to avoid damage.
radiomuseum.org has the valve base connections.
