Hey, I have two of those little sets! One carries a name brand of Invicta (i think) and i don't remember what the second one is. IIRC, they use AA5 tubes. The 35W4 and 35C5 tubes get pretty hot, and have created stress cracks in the cases because they are just barely below the top of the cabinet. I know that one if them actually works, but seems it needs something cause the audio starts to fade after 10 minutes or so.
Yes, the insides do look pretty cheesy, and the tiny chassis are kinda hard to work on. Guess i will have to get them out tomorrow and see if they still play.

I have one of these, it is a "Hi-Fi Master". Performance is good...the metal electrolytic cans used in Japanese sets still tend to be in good condition.
The IF circuitry cheats somehow...I think it uses an inductive coupled circuit with a single choke and capacitor to replace one of the traditional IF tranformers. There is a tiny schematic on the cabinet of mine that shows how it is wired but cannot remember exactly.

One question I forgot to ask...
In almost all the early electronics I have seen form Japan, the steel parts have this yellowish/goldish/greenish tint to them, as opposed to the regular silver/grey steel we see in American electronics. Is this some coating on the metal, or something form the manufacturing process?

Looks like the stuff labelled Monarch and Calrad which I think came out of the same plant as Kenwood/Trio/Realistic. That PS cap an Elna? Suzuki wire wounds?

Well, Max, have you got 'er goin' yet? I remember my dad brought me back from Louisville a similar set in about '64-I was 7 & all it would pick up was the local station, WRGS. Seems like it would pick it up from about halfway up the dial to the very end. WRGS is 1370 KC & you would start hearing splatter from it about 1100KC, IIRC. Don't remember what happened to the l'il fella, but it was Japanese, & was yellow & white plastic & tubes. Wished I had it now, but being the destructive little shit I was, it might have been lost in some "experiment".-Sandy G.-junior-league budding mad scientist

Those are carbon resistors, very similar to the way they were made here in the 30s. I think that may be a cadmium plating on the chassis.
