Hi,
Can anyone recognise this?

Image Link

It has nothing to do with my eBay lot, it's a friend's,
and I'd love to be able to provide that valve.
I told him at the start that I would recap his if I got mine working.
If I now have the valve, and test his Xformers,
the chassis is fresh, so it's got a good chance.

I guess it would be a rectifier.
These are the Milliwatt valves that I think Philips made.

You might wish to chuck some valve type numbers at us.
Is it a 4 valve or 5 valve job? Can't see behind one of the I.F. cans. At a guess, though I may be wrong, the valve line-up is probably, from left to right, if it is a 4 valver: 6AN7, 6N8, 6M5 & 6V4. I also have an appalling suspicion that what valves are there, are in the wrong sockets.

I don't have much else, that would be nightmare if the valves were shuffled.
I have been told the vales can't be read, and the dial glass is gone.
Maybe I can fix a different one.

It wont be too hard to find which sockets the output & rectifier valves go in to. The first 2 valves (from the left) should be a 6AN7 & 6N8.

If the valve type markings have gone & they are Philips/Miniwatt types the guide below should help to identify them. The codes in this guide will even tell you the month, year & which factory the valve was manufactured.
The codes are printed in tiny letters and numbers on the side or underneath the valve. You will need good eyesight and a magnifying glass.

The code for 6M5 is M+ for earlier Innoval types and WD for the later noval types.

Ok, thanks for that. I think I will end up with it here to look at.

Layout looks to me like a Philips/Mullard chassis from early fifties. Unusual to see a 4-valve lineup that does not appear to have a front-facing speaker behind the dial, as you would expect in a mantel radio. Chassis mounting holes suggest possibly from a wooden cabinet, but there's no pick-up terminals so not a radiogram. Maybe some unusual console?

Valve on far left looks fatter than the others, so could be a rectifier like 6XG in the wrong socket.

There's got to be some identifying serial number on the chassis somewhere.

I will get back, but I do think it is a horizontal wooden console,
potentially the type that also has a record player, but not sure.
I'm only getting the chassis to work on.

Arts & P says 5 valve Bigger valve may be 6M5 which is the OP Pentode. That socket will be easy as it will have the speaker transformer primary on it and is a 9 pin as is 6AN7; 6BE6 is a smaller size converter& 7pin.

If the rectifier is 6X4 its a 7pin. Stencil is not what I have seen on Philips similar to Breville albeit the transformer is similar to Philips. That type in Philips transformer often had the wire escaping from the wrap.

More info as it comes to you, required.

Miniwatt is not a guarantee its Philips. Tasma used a lot of Philips valves.

There is a fifth valve socket directly behind the far left IF Xformer in that photo.
I do have another photo top down.
I should be able to do better with info,
brands of transformers, speaker brand, etc.

If the valves have been misplaced, there's a good chance I
can populate it with valves to test now, so long as I know the valve set.

Thanks Smile

Thanks for the help, I guess I do have to wait for my friend.
He sounds like more of a hoarder than a fixer,
and is supposed to be coming for a couple of empty cabinets
I offered him.
