I got this at the Howard County, MD hamfest yesterday. It appears to be a Philips; the tubes are all those funky
Philips "miniwatt" red spray-shield tubes. All date coded 1942 Wehrmacht.
This receiver covers 1.5-30 MHz and is extremely interesting in that the tuning and bandspread capacitors are of the piston type. You can see the variable capacitors (4 sections) in the top view (I removed the cover as I had to unfreeze the mechanism) and in the bottom view (this is the bandspread cap).
The front panel is in English and is engraved. I know the Dutch are some of the best English speakers in the world - but would this be normal circa WWII? Certainly, occupied Holland would have been pressured to make equipment with German lettering. Then too, the rubes could be WWII old stock and the radio made postwar.
Someone pulled all the tubes, clipped the grid caps off, and shoved the mess in a box. I'm missing a tube or two... here's the tubes I have: AZ1 (obviously the rectifier), HTC150 (looks like a VR-150 equivalent), EBF2 4 of them (is this a remote cutoff pentode?), ECH3, EF8, and EF9. I am missing at least one tube.
It appears that the small tube socket towards the rear of the RF compartment might be a neon bulb? Its top cap connection is in parallel with the grid connection of the next tube - most likely the first RF. So there would be 1 RF, mixer, oscillator... what's the likely placement of these tubes and what's missing?
Here are the pics:
