Notes

The Sparton models Triolian use three electrodynamic speakers. This model 136 has a push-pull audio amplifier using 2 x 2 type 2A5 tubes in parallel. The center speaker measures 12" in diameter, the two others 8". The models 134 and 136 share the same Rider's schematic and have 5 tuning bands with a range from 540 kHz up to 24 MHz. The bands change in color of background light to each separate band as bandswitch is changed. The 136 has a more modern cabinet than the 134 both are then "the top of the line".
The VisoGlo tuning indicator VG-1 is extremely rare, even in the literature it is nearly not noticed. See the article here about season 1934/35.
