And... some more radios from my collection! I won't bother posting Zeniths, Grundigs, etc. Those have already been shown!
Various other not-so-common sets to follow.

File comment: Loewe Opta T86. This is one of my favorites. 2 speakers, sounds good, looks really nice, with the rosewood colored plastic. (Ignore the washing machine wording!)

I'm on a roll here! Some more sets from the collection.


Attachments:
File comment: A German made GE World Monitor. GE bought up a German radio company - Kuba, and put their name on one of their sets, it seems. Sounds as good as the other German sets of its size. 5 batteries inside.

I found four transistor radios at an antiques mall over the weekend. My favorites are the 4-transistor Sylvania 4P19W (that has surprisingly good audio fidelity with room filling volume) and the 10-transistor GE P1704B.

The Sylvania has the CONELRAD triangles on the dial. The GE is a bit more recent and had badly leaked AA batteries inside. Replacing the three electrolytic caps, one resistor, and some factory cold-solder joints brought it back to life. I also rebuilt one battery clip that had been completely eaten away. This radio is limited by the speaker--audio is tinny but sounds better on headphones.

Not pictured are Juliette and Channel Master pocket radios, which I'll probably sell to offset my expenditure on these two keepers.

I have one of the Sylvania 4P19W's, and agree it's good performer, especially for having just four Transistors. It uses a kind of unique reflex circuit to accomplish results beyond it's Transistor count limitation.

Yes, it's a pretty clever design. Guess they wanted to squeeze as much operating time out of a 9V battery as possible... :lol: The selectivity isn't as great as the 10-transistor GE, which is easily able to separate stations at 1010, 1030, and 1060 kHz.

My latest buy $8.00 at an estate sale. Cleaned it up including 4 batteries that had leaked so bad they split. Works great. Zenith RE94Y

Here's what happens when you put Batteries in a radio in 2000 and leave them there for 21 years. Working now on cleaning and repairing batt system

Hello all! For whatever reason I've started a small collection of pocket radios. :o My first was the NEC NT-625 from a local antique store. Not sure why but I just liked the way it looked and was wondering if I could get it working. A few months later I now have six radios. All these radio's are working except the Channel Master because I haven't opened and cleaned it yet. Of these radio's I really like the Toshiba pair. While looking for old radios online I came across the pics of them together and just had to have them. The M was from Connecticut and the S came from Spain. I picked up the Sanyo because of it's futuristic look. It's not super old but it has a design I just love to look at. The Channel Master will get some attention soon and the newly acquired HEBCKUU 402 is quite strange. The little antenna topper is missing and I'm not totally sure where to find an original replacement. I really want to start working on a display for these. So far it's been fun tinkering with them and I'm sure they won't be the last.

From left to right:

Channel Master 6503
NEC NT-625
Toshiba 7TP-352S
Toshiba 7TP-352M
HEBCKUU 402
Sanyo RP-1250

Nice haul of 80's stuff! In your picture the bigger of the small TV sets on the right. I believe my dad use to have one of those! I would play Nintendo games on it even though it was hard to see! LOL

And fifties! That's a serious collection! Very nice!

Got this today. National Panasonic T-801 S. It doesn't work, but it was free. Battery holder is in poor shape, so I'll dig into it and see what transpires. Anyone got the schematic?

Nice pickup there, Colin old boy, and the price was right, LOL!

I've got a model R-223R that I've never had to open up. Works terrific (as most Panasonic branded equipment does).

Yours, from 1962 or so, most likely just needs a recap.

Richard, I hope you're right about the recap. The last Panasonic I had I never could get to work properly, and I gave it away (to John if memory serves me correctly). I will make more of an effort with this one.

That one of yours looks like a nice set. I bet with the RF amplifier it performs well.

Colin

Hey Colin,

yeah, the Panasonic is one of my best performers. As you know, SOP for restoration of any period radio is replacing the Electrolytics, as the first step. That usually gets 90% of them singing again. If it's stone cold dead, you might also want to check the earphone jack contacts, to make sure they are touching.

Richard
