[TenTec] ten tec orion II power relay replacement

[denton sprague <denton@oregontrail.net>]

After several months of flakiness, the dc power relay in my Orion II decided to 
pretty much stay closed (on) all the time despite the front panel on/off switch 
position.

Sometimes the relay will stay on for a few minutes, with the power switch in 
off position, then the relay will switch off.

Shutting off the power supply itself  until the Orion cools down just about 
always put the relay in the off position.

So assuming the relay is just about toast, I am looking for the aftermarket 
part number and where to get the dc power relay…

Anything else other than the relay that could be causing the problem? 

The power switch seems to be ok.
