i have a similar but different philips tuner/amp, the phono/gram input would be for a crystal/ceramic pickup deck, mine has 4 big TO3 cased transistor on the base panel, so likely a higher power output model
The "gram"(gramophone) input would definitely be for a ceramic or crystal cartridge equipped turntable. I think if this was a true HiFi, the input would be suitable for a magnetic cartridge with the pre-amplification and RIAA equalization, and the input might be labelled as "disc" or "phono". Also it would have a grounding terminal, that magnetic cartridge turntables require. The odd holes at the back, look like they're for stowing a two prong European type plug
careful with grommets in contact with the dial plate, if its plastic, if the grommets are pvc not rubber, 'stuff' can leach out of them over time and eat into the plastic!
be careful replacing bulbs, you often need the exact types, or ones with a least same or lower current, going higher could cause issues or even cause damage( i have an armstrong thing that needs a 50v 50mA thing!)
I come across this before. I've got an early 70s Radionic X40 electronics construction kit, that has 6v 40mA bulbs in it. And there's a warning in the instruction manual, about not replacing the bulbs with a higher current rating, as that could damage the transistors in the kit. I don't know what the transistors actually are, as they're unmarked dome top TO106 package silicon type. Some of the experiments are things like multi-vibrator circuits, that flash the bulbs.
0.64uf? typical of philips to use a non standard value! try and fit a 0.68uf poly, it'll never give trouble again, 😉 if you cant find/get one, i have some..
Beautiful looking set...
inductive tuners were a bit of a philips 'thing' ,some of their valve radios also used inductive tuning for AM ranges, i have a few ..
those 'strange cutouts' are to park the mains plug, it'd have been supplied with a 2 pin europlug

was the gram for a ceramic cartridge maybe, that dont need eq if driving into 1meg ohm?
keep going with the schoolboy humor, suits me sir !
I have a Roberts rm 50 that has also a rod adjuster on the back.
i used to have a rm40, almost identical, but now sold it

Philips, where is all plastic?
