I recently acquired this radio on EBay. What a monster! It is far bigger and heavier than it looks in the photos and requires full restoration. Luckily the seller offered to deliver it on a trip to Sydney. The valve line up is AF3, AK2, AF3, ABC1, AL2 and AZ1.

It is an all wave model with shadow meter tuning. It looks as though a few caps have been changed but otherwise it appears to be original. To be honest, there are a few components that I cannot identify such as the bank of 15 cannisters behind the main transformer. I don't thing that working on it will be straight forward.

Looks to be an import from Holland:

As you can see, they have the schematic, but you need to be a member of the Radiomuseum to access it. I don't know if we have any such members on this Forum.

If no luck here, you could try emailing:

Many Dutch people have English as a second language.

I have a Radio club member, of Dutch origin, who goes back and forth regularly.

If it is actually built in Holland, you might be in luck?.

He may be able to source info from Holland, or already has it as he collects Philips sets. Rectifier may be an issue if it has failed. "P" type are getting rare.

It may actually be similar to the 1937 sets, as they used those valves a lot, but changed to EZ3 rectifier.

Me either. I find chassis like that quite intimidating, still, it couldn't be European unless it was a complex design.

This radio will look great once restored though. Good luck with it.

Described as: Superhet with RF-stage, 2 AF stages, 7 AM circuits, 3 short wave bands and tuning indicator.

Yes, that's a busy chassis.

Fascinating beast - perhaps it has switchable tuning.

Good sites for the tuning indicator are

"Fascinating beast - perhaps it has switchable tuning."

Yes. the centre knob allows for six different wavelength settings.

Another quirk is that the chassis cannot simply be undone and removed after the knobs have been taken off. There are at least four wires that have to be cut or de-soldered in order to get it out. The dial lights look like car bulbs.

That is actually less complex than a 16 valve Muti band Midwest like the one I have on the bench. I have had dealings with an 18 valve one as well.

That clearly has three sets of coils for each band one for the 1st RF one aerial one oscillator. Plus one or two IF coils.

The circuit will be little different from a normal BC/SW Autodyne. There may be a bit of cathode or other resistor switching.

Why I say that is, Midwest did that to maintain oscillation at different frequencies. Their Autodyne, in one, has a seperate oscillator and four gangs due to it having a colpitts oscillator. (colpitts needs two gangs)
