Default Re: Radio ID please. No markings, possibly a kit set.

I built the Premier Radio (Edgware Road shop) version in this case and it was LW/MW/SW. Valve lineup 6K8, 6K7, 6SQ7,and 6V6 so I suspect this is a Pilot Radio job. Also the Premier kit I built had an autotransformer for the 6.3V heaters and a selenium rectifier for HT so was "live chassis". I developed a healthy respect for the mains, As my boss said, "Until the fuse blows you have Battersea Power Station on the end of that cable" a lesson well learnt!

Ref.#19.

Here are some pictures of my kit radio, which is on the bench as I am ordering components for a Bush radio and I might as well save on postage.

The selenium rectifier has been replaced with a diode and a capacitor.

More info to follow.

V1 no markings, possibly 6K7.

V2 6J7.

V3 6V6.

Can anyone confirm this as a kit radio or a commercial item?

Can anybody provide a circuit diagram?

Currently working but has a lot of buzz / interference, opening the fridge door makes it go crazy! (it's the light that's causing the problem).

Default Re: Radio ID please. No markings, possibly a kit set.

I'll stake 99% that it's a kit. Lots of kit sets at the time used that cabinet, a variation of a Pilot Little Maestro from around 1946. It could be a Barton or a Premier. Yours is a TRF so probably good for local stations.

I have a Barton using an identical cabinet but it is superhet with three wavebands. The only circuit that will exist for yours will be the one supplied with the kit. You could try a Google search using Barton kit set or Premier kit set and see what comes up. However it was common for them to use whatever valves were available cheaply at the time so you may not find an exact circuit.

One Premier TRF used a small transmitting valve as an output valve!

With that valve complement it's likely to be 6K7 RF amp, 6J7 anode bend detector (or possibly leaky grid detector) and the 6V6 as output.

Thanks Sideband, I'll do some more research.

First thing on the list will be a snubber to kill the interference from the fridge... And the central heating and the fluorescent lights and the dishwasher!

There's one of the Premier 3 valve TRF schematics here:

https://vintage-radio.net/forum/atta...0&d=1144184530

It would appear that the component values are also included in what might be the same schematic available from here:

https://www.radiomuseum.org/r/premie...radio_kit.html

Anode bend detector in the above schematics, the cathode bias resistor in series with the detectors cathode is the give away.

A somewhat better aerial may be all that is required. Possibly extending to outside the house if not already so placed.
Make sure the aerial series capacitor is a high-voltage type for safety's sake.
Is there a capacitor across the mains input? If not, this can sometimes help to reduce locally generated hash. Tony.
