[TenTec] [] Running a Century 21 on external 12V power

[Josh Gibbs]

Just noticed this C21 Digital on eBay:

"Although there is no sign of power supply trouble on receive, other than
just a soft trace of hum that I find hardly noticeable..."

If you look at the pics of the insides, someone has relocated the bridge
rectifier from the power board to the chassis, unless that was something
that Ten-Tec started doing? This one is only slightly newer than mine
(serial numbers differ by about 240).
