Default Gamages Radio

I have in my possession a valve radio with the Gamages logo on the scale plate. There is no other markings on the case or chassis to identify this radio. The valve lineup is 7S7 Frequency Changer, 7B7 IF Pentode, EBC33 Audio Triode, 7C5 Audio Output and 7Y4 Rectifier. The set is a 3 band LW, MW and Shortwave.

By the valve lineup I would suggest a date around 1950. Can anybody help with further information, since searching the Internet only gives details of radio equipment prior to WW2.

Gamages was a large department store in London. An uncle of mine used to send me Gamages branded recording tape as birthday presents.

There were loads of 'no-name' radios built by small outfits to serve the needs of the chain-stores of the time.

Trying to positively identify the maker and get a circuit/schematic can be a hell of a task: often the same outer-case [produced by a 'jobbing' cabinet-maker business] could house one of a number of different radio-chassis, sourced from similar 'jobbing' radio-businesses.

If you're lucky you may find that the radio was made by one of the bigger producers, such as Plessey.

Can you post some photos in the hope someone may recognise what you've got?

Attached are views of this radio, perhaps somebody will recognise this radio.

Many radios of this type were made by small manufacturers in the late 40s, often set up by engineers who'd learned their trade in radio and radar during the war. They often used whatever components were available cheaply on the surplus market, and the odd mixture of octal and B8B Loctal valves is typical. My guess would be that Gamages signed an agreement with some man-in-a-shed operation in Croydon or wherever to make these radios for them. The cabinets may have come from an additional furniture manufacturer.

The circuit is likely to be a standard 4 valve L/M/S superhet plus a rectifier.

It looks like a standard chassis made by Plessey as used by Regentone

To me, the tuning scale seems to be "Bush" in style.

It looks like it was made by Strad, the nearest chassis on RM is the 553W.

Is the power transformer possibly a replacement item? Made by Elstone.

The knobs look the same as those used on the Strad 511 (RM Electric)

Black Magic coffee cream knobs. Strad for sure unless they were a generic knob.
The chassis shape with the corners of the back plane cut back is very familiar too.
I was trying to recognise the IF transformers, but failed.

Why the EBC33 though? (Unless it's a later replacement with a socket change).

Looking at the chassis photo it looks like EBC33 either printed or written on the chassis, nothing conclusive from that photo though to suggest that the EBC33 was originally fitted.

I would not think this uses a Plessey chassis as it has an R&A speaker.

On second thoughts the valve holder rivets look undisturbed?

RM Electric made sets for other brands like 'Rolland' so could have made this. The cut corners of the chassis is also seen on RM sets.

Has your speaker baffle board got a bad case of woodworm?

The use of a R&A speaker makes me think of Pye maybe?
