I recently aquired a Motorola Ranger X31N AM transistor radio. It's in a brown leather case and works great. Cosmetically it's a 8/10 and the battery compartment shows no damage at all. I think it saw use, but very little. It has a small black push button on the upper left corner of the front case that I'm thinking should illuminate the channel scale, but it doesn't do anything when you press it (maybe someone can confirm that's what it's supposed to do.) It sounds great and the tuner is really sensitive. The only issue is it has an area while tuning (between 700-800) where it just hums/harsh static. Before/after it tunes great. The tuning dial seems to feel gritty in that area so maybe it just needs cleaned. If that's the case, what should I use to clean it. I am a laymen with radios, but mechanically inclined. Also, what is the approx worth of this radio in this condition?

I also recently saw a Sublime micro/mini (4 inch sqare case) transistor radio at an antique dealer that was literally brand new. It didn't have a box/manual, but I opened the case and it had what might be a period 9 volt battery (was blue/white and japanese.) The insert inside the case indicated that the components were all manufactured in Japan, but the radio was assembled in Korea. It was a black plastic case with tuner/volume knobs on the right side, with the Sublime emblem in silver front top centered. I can't find anything on this radio or about sublime on the internet. They want $37 for it. I was wondering if anyone has ever seen one of these, or knows anything about the Sublime radios.

Hello Sarge,

Welcome to ARF !

Not personally familiar with that radio, but did find one online
which sold recently for $22.99 at Bonanzle. Was in really good
cosmetic shape ( like yours ), but believe they said it didn't work.

Is the tuning cap the "open" type with exposed aluminum
plates ? If so, you may be able to clean it fairly easily with a
careful blast of clean compressed air. If there is something on
plates, use small strips of sturdy, thin paper saturated with
isopropyl alcohol and very carefully move them through plate gaps
with cap "wide-open" followed by air blast. Of course this cleaning
method depends on whether or not you have enough clearance
around tuning cap. You might also be able to use some electronics-
safe spray cleaner, but be careful where it goes---if possible, wrap
small piece of paper towel or clean cloth around it to keep spray off
of surrounding components ! Also, use as little as possible as you
don't want to affect the shaft bearings lubrication... And it's also
possible that someone could have "bumped" plates and bent them
enough so they short at that point in rotation...

Have no clue on the "Sublime" radio...

Best of luck...
