Well the projects just keep coming!
I just picked up a Philips PA Cabinet with a J052B Radio, 950 Amplifier and Garrard turntable.
For Philips it seems to be a little over designed as there are pots everywhere to adjust levels at several stages.
Certainly not high powered, would guess around 15/16 watts with a 6V6 push pull output driven by another 6V6.
Also figuring about 1947 in age which makes it the oldest PA system I have

I have a similar system though without the turntable. It was made by STC and contains three seven valve radios with magic eyes on each plus a PA function and inputs for an external turntable. It was the piped music system for the old Royal Ryde Rehabilitation Hospital and was disposed of in 1994 when I was working there as an electrician. It sort of slipped out of the skip and fell into my box trailer so I was obliged to save it from a certain trip to the tip.
These systems could have found a place in shopping centres of the time too and perhaps public halls.
Sadly, I don't know what happened to the top chassis and would need to acquire one to be able to completely restore the unit.
This class of receiver would be quite rare now and amongst the rarest of all radios, even if their monetary value isn't so great.

A valve a day keeps the transistor away...

I love that radio rack, havn't ever seen one before.
Can remember the old air tube headphones they would have been piped through
that were about as comfortable as a concrete helmet!
Monetary value is low priority as to the History of them is the most important which is why my pet hate is seeing them converted into guitar amps.
With my rack I was thinking also a small school as the larger schools usually had
a few zone switches on them and 16w would be a bit light on.
Also the choice of turntable is a bit strange as its a 78 only with a pitch control and also its a
single Mic input.
Im also unsure if the unit originated here when it was in service as at the time Nomis, Bland Radio
and to a lesser extent Farmers Radio Service were the main option in SA
I have a Nomis version (smaller) awaiting pickup from a friends in Ballarat
that was out of a club in Broken Hill.
It has 6 zone switches but they used a long play cart deck instead of a turntable.
So there were Many options out there.

This system had 'electronic' pipes but the distribution principles were the same. The three radios gave patients a choice of three stations and the gramophone input would have been for a fourth internal channel.
