Zenith "Zenette" model 4G800
3 way (AC/DC/Battery) Portable

A small set with a flip-up lid and it works perfectly. Made of solid color maroon plastic with no damage. These are hard to find without cracks and damage to the case. Near perfect condition with only a few minor scratches which can be rubbed out if one so desires and uses the right material and technique.

National
model ?

An attractive, early, large style coat-pocket size, 4 tube portable radio in beautiful cosmetic condition. Made to operate on battery only. I find no information on this, the National Co. is famous for their communications receivers but I'm not sure if this was made by the same company.

Olympic
models 445 & 447

These will be of interest to those that like historic items.

What makes these sets interesting is the transistor version. The tube set (model 445) is standard fare. The transistor version (model 447) is quite interesting. It's seems that Olympic was in such a hurry to get a transistor radio on the market in the mid 1950's (as was all manufacturers) that they took their tube version and simply modified it by stuffing transistors into the tube sockets and made other necessary circuit changes using the same chassis and layout. They added a trim piece that read: "ALL TRANSISTOR" across the bottom of the case and voila, they had their first all transistor radio.

Year: 1954
Case: plastic
Number of tubes: 4 tube - 4 transistors

Battery requirements:
Frequency coverage: AM
Antenna requirements: built-in loop antenna

Zenith model 6G801 AC/battery  tube portable

An excellent performer with really good sound quality. Streamlined styling, push on a button (top center) and the doors open and the antenna pops up from rear. I done a meticulous restoration of this fine set and it's excellent for everyday use considering the tube used are the low power, low heat type. One of the things that make this radio such a good performer is the RF stage which provides very good long distance reception. The antenna can be removed and with the (included) extension cable and suction cup accessory (made to stick the antenna to the window of a train) makes reception even better.

Year: 1946
Case: plastic and metal
Power requirements: 120 Volt AC/DC
Battery requirements:  9
volt "A", 90 volt "B"
