Unknown amplifier with Philips F443 pentode (Gezocht)
Looks like a total DC current amplifier with al those big resistors and ballast lamps.
Would be great if you get thing going.
It is very likely a DC-supplied amplifier: up until 1945 the Danish grid was 220 VDC fed by many local powerstations.
Kind regards, EJ
