LOVE the T/O...Somethin' about those guys just says "Class"...Don't matter if its one of the SS versions, or the old Tooob types, they're just "Grand", in the same way a '41 Packard is, too...

GE AM/FM table radio

Hi dawgs,

I have that radio; believe it's from the mid-late 70s. I don't know how to read GE date codes. On the label on the bottom it reads: Model No. 7-4115B, date code 4306, made in Malaysia. Also have a very similar clock-radio version, with the clock where the speaker is in the non-clock model, and a rear-firing speaker. Both receive well and sound very good for very basic, cheap radios.

Sorry I can't post pix but my camera is out of whack.

Love your Telefunken Concertino; I'd like one of those but they cost a small fortune whenever I come across one.

My brother brought me this early-70's Panasonic RF-951. It needs a good cleaning but seems to work alright. I'll probably wind up selling this one.

Grundig S350. All transistor Zenith Oceanic R 600? All tubes burned
out long ago. Found a solid state tube substitute for all of them
so does this count as a transistor multiband radio? 1 set of batteries
lasts 250 hours with 4 AA's, 1 D, and 10 9v. (to be fair, light is not
to be left on for the 250 hour range:-) 9v are rechargeable NIMH and
must be charged individually. The grundig S350 is the sorriest specimen
of a receiver I have ever owned. Allthough digital/analog the display
sometimes gives way off readings, the radio drifts even on FM and
I use it less often then the older sets.

Grundig's quality went right out the window, IMHO, when they started outsourcing everything to China. Just sayin'.

Talking Grundig G6 Aviator

Not sure if this counts as this is not vintage. It is a Grundig G6 Aviator AM FM Longwave Shortwave Aircraft band pocket portable. Performs very well for a radio of this size. Gets most Shortwave stations with just the built in whip Antenna. Long range am not bad. Havent gotten anything on the aircraft band yet.

I have one too, a good little radio. I d pickup aircraft in the aircraft band but I live near the airport.

Here's a curb-find Sony ICF-38 that I got several years ago and have begun to use quite a bit around the house and outside. I found an open tracing at the detector. After a small amount of clean up, a jumper and fresh batteries, it was good to go. Has good sound quality with its 3.75" speaker, decent sensitivity and very good selectivity. Runs on 4 AA's or internal AC supply.

Those Sony radios are great. I have a TFM-7720-W AM/FM portable which I rescued from a dumpster. Works very well, good sensitivity and selectivity, great sound for a small portable. The only problem I'm having with it at the moment is an intermittent somewhere around the volume control. I can restore the sound by tapping on the volume knob on the front panel. I'd try to repair it, but I'm a bit leery of working on circuit boards after having had a bad experience with a PC board in an old TV years ago.

The TFM-7720W is one of those well-built radios you just don't see anymore. While I would not say this radio is built like a tank, it is, IMHO, quite solidly constructed and probably wasn't cheap when it was new in the early 1970s (1973, to be exact).

One thing puzzles me about that radio, though. It runs on two D-size flashlight batteries, which I consider odd since most of these radios use four, six or more C-cells. I have a Zenith TransOceanic from the late '50s that uses nine D-cells -- eight for the radio and one for the dial light. However, my three-volt Sony portable is a mystery to me. How could Sony design this set to operate on just three volts? The audio output isn't that great, probably much less than one watt, and there is only one pilot lamp in the set, for the tuning indicator.

I apologize for the poor picture (my camera takes great pictures for being a 1.3-mp cheapie from Radio Shack, but I was in a hurry so I took the photo on the fly), but I believe it is sharp enough that you can get an idea of what the radio looks like.

Not much telling, Jeff.
Sony's always had an fixation with odd voltages. 3, 4.5 and 7.5 volts isn't that uncommon on their radios, tape players, etc.
It kind of fits in with their oddball AC jacks they used to put on their stuff too.

Jeff, Silicon transistors require about 0.7 volts to turn them on, so I think that designing a radio to operate at below 1 volt or so would be difficult.
Several small pocket portables use only one cell, that is really the lowest practical limit.

The smallest AM/FM pocket radio with speaker that I have (S0ny ICF-S11W) uses 2 AAA cells:



But getting back to the intent of the thread, here is a S0ny AM/FM/SW Multiband radio (ICF- SW1), shown next to the S11W... It uses 2 AA cells for power, as well as a wall-wart and is a decent performer on SW.
