Folks,
I am also looking at a home made radio from the late 1940s (based on the valve line up I am guessing 1946/47 or so).
I suspect the chassis has been made from old biscuit tin thin steel, and the quality of the build isnt pretty(I dont think the builder had soldered prior to this build). One of the RCS tuning dial mechanisms is also in the build. Its not worth a full restore as its an absolute rats nest, but I am curious to get it working. Someone has already swapped a few caps and resistors in it (not neatly either).

Does anyone know if there is a listing of Radio and Hobbies magazine's various receiver sets, as I suspect it may be one of these (although there were other kits sold by stores too)? This unit has a 6J8G, 6U7G, 6B8G, 6V6G and 5Y3GT as its line up and doesnt appear to have anything special to differentiate it further. No labelling of any type as its all home made.

Thanks.

The August 1946 issue of R&H includes "A new mantel receiver" with this line up.
My email is unhidden if you want the circuit.

Thanks Harold,
I have all of the back issues and had started going through them today. I hadnt yet stumbled on the one youve mentioned (I started at an 1947 and was moving forward). Thanks.
I have had a quick look and it may be the circuit, but a closer look tomorrow in the workshop will be needed. Thanks again.

I think Harold is spot on.

That was the "Fireside 5" and an absolute classic circuit.
Page 18 in the issue.
I have the RH on disc, there was a CD available through SC and I have it loaded on all my PC's.

The set should work like a charm and well worth getting going as an exercise in understanding superhets of the time.
Let us know how you get on.

Fred.

Thanks.
A very quick look this morning and I dont think it is the same circuit.
Unless its been modified along the way.
Its very similar, as many with this line up will be, but quite a few component value differences of the few I had a quick look at.
Theres no PSU choke, only a power resistor (for example).
I think I might trace it out for the sake of the exercise, and for interest.

PS I have all the RH too, but its a bit of a slow process to go through them all. I have the CD, but I also have most editions in hardcopy too.
I enjoy reading magazines and books in paper, turning pages, looking at the old articles and ads. A great exercise in front of the workshop firepit with a drink in hand. It doesnt seem quite the same on a screen reading a PDF

Depends on the size of the screen!!

Yes the builder may have based the set on the RH circuit and substituted different parts.

Not a problem, just find out what the circuit is and make it work.

Fred.

There are bucket loads of circuits with that combination. Should not be an issue.

I have a Lekmek chassis that's now about number four in the line, as I got rid of a Wireless set No19 Mk3 that looks like it was designed to be "blown up" rather than fixed up. Seeing its been wet for the last couple of days; A Peter Pan stamped FKM and is actually an FNQ got sorted and has been replaced by another Peter Pan, But its got a 6A8 in that combination and the oscillator coil is floating in mid air. Horror of horrors, its got newish 450V filter caps. Never with a 5Y3 do you do that. Especially with the old leaking chassis mounts in circuit.

The Lekmek is a battery set chassis and now has that valve line up. Many of the sets with 6J8 were BC / SW as 6J8, with its separate Triode exciter superseded 6A8 albeit that 6A8 was not the worlds best Pentagrid.
