I take it the original pic was too large. It's too small now though lol

If you get a chance, pics of the outside of the case, side views and then with the set opened up would be good too - chances are it might have a maker's logo somewhere. Pretend you're going to try and sell it to me via eBay or something Both sides of the circuit board, the ferrite rod antenna etc.

It's vaugely similar to a set I used to own back in the early 80's. Didn't cost much, worked pretty well for what it was, only for the life of me I can't say what the maker's name was.

One thing to note - your radio has one too many IF transformers to be of the normal design.

That eBay picture - the box states it's a two waveband radio, I assume LW/MW. Seems to have a telescopic antenna though, so thats a curiosity.

edit: The eBay listing states LW/MW, so why the FM antenna......

It's MW/LW only.
Your right about the FM aspect. The antenna is only an ornament, as far as I can see. The PCB track to which it attaches is cut - as if drilled out, so it connects to nothing.
Maybe it was a general purpose PCB and could have been a three band also ?

No sign of a maker name. I've looked all over - both sides of PCB , case inside and out.

The back plate indicates the MW/LW band range and marked "Nationwide Model" . At present there are two more on ebay. One "President' , one "MonaLisa" . It looks to me like it was one that could be rebadged for each distributor, changing the aluminium strip on the front casing.

I think it more likely that the case was was a generic component - that board isn't an FM reciever, the TC is only a twin gang component and there's no FM tuner section - or component holes on the board for it to be made into one.

Really I'll need a larger picture, since the 5 IF stages seem odd, there should only be four - which leads me to believe that maybe there is an extra stage of RF amplification - but that's pretty unlikely in a budget disign such as that.

I've scanned the radio museum for the "mona lisa" and the model number TR-620A and it draws a blank. Google doesn't have a clue either.

hmmmm, curious!

Actually, I see 3 IF transformers (for 2 stages of IF amplification) and 2 oscillator coils (the reddish ones on the left)...one for LW and the other for MW.

Was your Ritatone radio made in Hong Kong?

The looks of the PCB, and garish blue case, as well as the non-functional 'AM whip antenna' reminds me of a radio I have.

It's an Astronic made in Hong Kong that looks like it was made in the late 60's or sometime during the 70's.

My Astronic is a bit smaller, though. But it's unique in that it not only has that non-functional whip antenna, it also has a dual dial scale:
One side of the dial is in Kilohertz, the other side is in Meters. Pretty cool.

@DragonForce, thanks for the info on the color code for the IF cans. I wasn't aware of that standard.

I've examined it inside and out , including the packing box and no indication at all of it's origin or manufacturer.

The case has room for a longer battery, but the extra space was blanked off with a black plastic spacer, reinforcing the idea that it was a generic case. In that case, the antenna would have had to be installed or two holes would have been left blank without it. Probably easier to fit it, and the customer would be impressed also

Oh! there is an ID on the back of the PCB. LM-820C. See pic attached,
