Thanks Arran;

If your set has five tubes/valves then it could be an A537, V537, or a U527, then again it looks like someone has replaced or added tube sockets/bases as Philco normally mounted them under the chassis with rivets.

I've looked everywhere on the chassis for a model number, there just the two labels riveted on the metalwork:-

but there is a number "A15001" stamped in the metalwork

I think you're right, it may well be a heavily modified set, the base at the front is riveted whilst the rest are screwed in.

It looks like the PENDD61 valve/tube must have failed, so someone replaced it with the EBC33, which is a double diode-triode like a 6Q7, and replaced the power output tube with whatever the other one is (can't find an EL53 is it an EL35?).

Well taking a closer look, it appears to be an EL33 not 53, the writing on the glass is badly degraded. There's also a smaller number under the Mullard logo, B3G1 if that makes a difference.

Now, given that I can't find any schematics for a FIVE valve model and it looks like it may be a heavily modified FOUR valve version, it's probably beyond my skillset to reverse engineer this back to working condition. A lot of the capacitors (sorry condensers) and resistors are barely readable. So I'm thinking it's time to call it a day. 

Also, the speaker cone is shot.

So if anyone wants it for spares, and you live in the UK, do please message me.

The bakelite case is good and so is the dial plastic
