Good afternoon,
I'm wondering if anyone has seen this radio before and if there is a schematic available.
Radio is a Rymola console radio. No model numbers or anything identifying is on the console or the chassis.
Valve lineup is ECH35, 6U7G, 6B6G, 6F6G and 5Y3GT. Speaker is a Rola K8.

Possibly dual wave model 5DA of 1946. The 6J8 can substitute for ECH35 and 6V6 for 6F6.
If you unhide your email address via Control Panel I'll send you the schematic for comparison with what you have.

I fixed this up as the NBN got shut off to do yet more maintenance: Virtually every month?
Cathode resistor will need changing to use 6V6 instead of 6F6

The radio pre-dates 1947, there is no 4KQ which began broadcasting in May 1947. 4QR is also in it's original position 940kHz changing to 590 kHz in September 1948.
I agree with GTC it could be a 5DA dual wave.

My guess from stations on dial is pre 1941.

That would have been likely the first of the post war production & as WD had scarpered off with a lot of RCA type valves, there were often several sets made or factory modified (HMV) to take Philips valves.
If it was originally made to take 6J8 then pin 1 may not have a ground, or there could be evidence of this being done later? The factory would have grounded pin1 as that is ECH35's shield.

Thanks for the input.
I can confirm that the ARTS&P sticker doesn't have a letter prefix which suggests post 1941 production.

Schematic emailed. Let us know if/how it accords with your chassis.

Thanks.
Some of the schematics line up, but some of it just doesn't correspond at all. Still deciding whether to take it back to spec if it is indeed that model.
There is one component that I have no idea what it is and I can't say I've ever seen. There are no markings on it, no identifying symbols or anything. One end goes to ground, and the other has resistors attached.

Most likely an oil-filled electrolytic capacitor.

Yes, an ancient capacitor.
