Cheap off brand TVs

[Rob]

Andy,

I took the liberty of reducing the picture size so that your text could be read.

I have seen Trav-ler sets with round CRT's shown in the late 40's Rider TV service manuals. I cannot offer further information. Your's sure demonstrates absolute minimal circuitry. Losing sync and sound volume with the contrast control is reminiscent of some of the 40's sets where they controlled contrast by adjusting the RF and IF gain with this pot. The sync and volume were taken off at the end of the gain adjusted IF chain and subject to fade with the control.
