More on Haynes-Griffin
BY WALLY WORTH
A number of Haynes-Griffin radios were the subjects of Wally Worth's article in the August 2001 issue of A.R.C. In this article, Wally provides information on a Haynes-Griffin Superhet. (Editor)
Haynes-Griffin radios using TRF and regenerative circuits are well-known to radio collectors. Perhaps not as familiar is the superheterodyne receiver described below.
Shown in Figure 1 is an 8-tube Haynes-Griffin Superhet that I recently discovered. It features 2-knob tuning and uses Type 01-A tubes. Its Bakelite panel size is 7" x 24". The walnut cabinet is not home built, but factory-made.
An interior view of the radio is provided in Figure 2. Components are mounted on the Bakelite front panel and wooden base. The IF transformers, located at the right rear, are all marked "Haynes-Griffin." The Koras audio transformer may be a replacement. The two stages of audio amplification at the left side of Figure 2 are resistance coupled. The RF transformer located between the two panel-mounted tuning capacitors is a Dubilier "Duratran." Battery connections are made by seven binding posts on the rear of the cabinet.
Wiring consists of uninsulated tinned copper wire (often refered to as bus-bar wiring), and some insulated, stranded, flexible wire. The quality of the wiring suggests that the radio was built from a kit rather than a factory-produced radio. Since the front panel was unengraved, I added the "Haynes-Griffin" legend for identification.
Although I have not tried to connect up the Haynes-Griffin superhet to a power supply and actually play the set, it is in such very good condition that I have no doubts it would not disappoint me.

At age 15, Wally Worth began saving his paper-route money to buy parts to build 1-tube sets. Fifty years later, he started to collect anything that needed cabinet work. His diverse collecting tastes include crystal sets, 1920s battery sets, novelty radios, tubes, and both horn and cone speakers.
Figure 1. This front panel view of the Haynes-Griffin Superhet shows the two main tuning control dials, the two rheostat controls beside the two dials, the off-on switch (lower right), and the two phone jacks at the far left.
Figure 2. The layout of this 8-tube Haynes-Griffin chassis shows the complexity of those early su-perhets. However, the components are neatly arranged and not too crowded.
