Braidio 32 - UK Vintage Radio Repair and Restoration Discussion Forum

Yesterday I staggered home with 3 valve radios. And amazingly I don't have service information (exactly) for any of them. I'll mention 2 of them in passing :

Vidor CN435Z : One of those 4-valve battery portables with a frame aerial in the lid. DK96, etc valves. I have the R&TVS books that cover it, it's similar to a CN434 with minor circuit changes and it's built on a PCB (not a hardwired chassis).

Ekco U319A : I am not sure how this differs from the U319 (if at all). I have service information on the latter and suspect it will be enough.

So on to the real 'unknown' set. A Braidio 32. 5 octal valves, I could read ECH35, EF39 and EBC31 on 3 of them. The other 2 (larger clear glass envelopes) are I assume the output valve, possibly an EL33 and rectifier (AZ31?). I read that it may have been made by Ekco, but it doesn't seem to match up with any normal Ekco chassis.

There are some horrible-looking cardboard cased cuboidal electrolytic capacitors under the chassis. Those will certainly need replacement.

Before I resign myself to tracing out the circuit, etc, does anyone have any information on it.

Not Much help I know

Most Briradio sets look Quite EKCO like but this one not so much more like Pilot even?

Cheers

Externally it looks a bit like a Radio Rentals model 58 and may have the same chassis.

The rear is similar to the Radio Rentals model 56.

The bakelite case is very similar to the Radio Rentals model 59.

I think it's close but not identical to those Radio Rentals sets. Possibly the circuits are similar enough that the service data on the DVD will be a help.
