Stewart Warner Radio Model 61T26

Circa 1946

This radio is a 6-tube AA6-type receiver. This set is also an excellent performer. With a tuned RF stage, and permeability tuning, it is very sensitive, selective, and more immune to noise than capacitor-tuned radios. This set outperforms all of my other standard-broadcast AM radios, even my Hallicrafters S-85. This set is a step in my quest to obtain a Woolaroc model 3-1A, which is the same chassis in a different cabinet. Stewart-Warner was amongst the many radio manufacturers that supplied radios to Philips Petroleum which they sold under the name Woolaroc. In the mid 1990's, I got to surf the dial in the evenings and at night one weekend on this model radio in a lakeside cabin, and was very impressed with the set's performance.

The cabinet is Bakelite wit ivory finish. I suspect it has been repainted at some point in time.

The functions of the knobs from left to right are: volume/on-off; tuning, and two-position voice/music tone.

Above is a rear view of the radio. The antenna is the wood frame, and has grooves around the perimeter with 14-gage wire for the antenna.

Above, after restoration. Since I want to use this radio frequently, it made sense to go ahead and replace all the wax caps and redo the electrolytic caps. I kept the two orange drops because they were good, and the correct values

ID Type Function
V1 12SK7 RF Amplifier
V2 12SA7 Converter-Oscillator
V3 12SF7 Intermediate Frequency Amplifier-Detector-AVC
V4 12SK7 Audio Amplifier
V5 35L6-GT Beam Power Audio Output
V6 35Z5-GT Rectifier

The intermediate frequency is 455Kc. Note the unusual tube line-up. All pentode amplifier tubes, and the detector tube is combined with the IF stage instead of the first audio stage.
