Default Bought an Old Valve Radio Today!

Looked the radio up on the net.


Shoulda done that first. Or looked for a tube location chart somewhere
inside the radio.


No, there isn't one, and there are no markings on the PCB or stuck by the
valve bases.

I'll try and get hold of some replacement valves.


A circuit diagram, or a generic diagram for a radio using the same valves,
would be a good idea. Specs/pinouts of the valves as well.


Well, I am pretty sure I have the valves in the right sockets
now. It's FAR more promising with the current line-up than it was with
any other permutation. It could even be working, and there are no MW or
LW stations with enough signal round here, but I don't believe that! I
think it's not working. Plus I did find one pic on the net that had the
locations of two of the four valves marked, and that's how I have it now,
so that narrows things down.

I'm just not convinced that I haven't fried a passive component
or two.

No, I haven't fried a thing of beauty or value. 10 or 15 quid
seems to be about the going rate for them. I paid 10 plus a
fiver postage. I think I have a valve supplier sorted, and they
seem to be less than 3 quid each, and I'm sure the audio output
valve is fine, so that's only 3 to replace, and I reckon only
one or two of them will actually need replacing.

I was a little disappointed to find it uses a PCB. I was hoping for
a chassis-based radio that I could kinda strip down to the chassis,
polish up, and have around as a cool valve radio curio that worked,
but the PCB kinda detracts from the look of the thing, really. But I'm
prepared to at least get a new set of valves and poke around some more
for dead-looking resistors.

We'll see what develops.
