I've bougth an AIWA (the first AIWA in my collection 
).
I was nicely surprised with the sound quality
. Not to much power but great quality.
The unit had two major problems. The first (dead line-in) wasn't noticed when I had purchased it.
And the second (dead motor) appeared after purchased
.
The line in was pretty easy to fix, it were two corroded tracks on the PCB. I guess that the vinilic tape they used to hold the wires aginst the PCB concentrate moisture that can corrode the tracks from the PCB, so I take all this tape out
The second looked very easy too. The motor started to work after helping it with my hand. Looked like one of the three windings wasn't making good contact.
I replaced with a fresh one (I have many motors in stock AJAJAJA).
It's a standard 2400 RPM motor. But to my suprise, the speed cannot be regulated at all. That's, with the preset at min, the speed is still a bit fast (not noticeable at all, so I left this motor installed).
Does this Aiwa takes an special kind of motor ?
The original says "AIWA", but it's clearly from MITSUMI. Uses the same kind of codification and had the MITSUMI LOGO !!!!. So when I saw that, I imagine that it could be replaced without problems. But now I figure that it isn't standard
.
The only way could be modifing the internal circuit form the new motor to wider the speed adjust range.
Have anyone done this thing ???????????????????????????
