Japanese Tube Radio

I picked this set up over the weekend at a yard sale, we all know of the Japanese transistor radios, but there was also tube radios, mostly smaller AM radios that were sold under various brand names (the nameplate is missing from this set)
This look like an earlier radio, based on the styling and the fact that is still sues a point to point steel chassis, I was expecting a PC board in this little radio.

Some other interesting things that set it apart form its American made counterparts:
- The filter cap looks like a modern one, a metal tube covered in plastic, instead of an uncovered metal tube or a cardboard tube, it is also a clamp mounted cap, something I have only seen in older radios from the 30s.
- There is only one IF transformer on the top of the chassis
- All the resistors look like they are wire wound
- The tuning condenser and output transformer looks smaller than normal to me?
-This radio does use wax capacitors, but they look cheaper made than the American caps, they seem to be leaking much more wax than normal, and the paper is coming off some of them.

Just though I would share some observations on this set, since you don't see these too often, they were probably thrown out when they broke (this set was actually repaired at some time, the rectifier tube was replaced with a RCA)
I haven't powered this set up yet, but will soon, those bad looking wax caps will probably have to go though.
