[TenTec] Need OVP advice for Ten Tec 262

[Curt]

I recently bought a used 262G for a Triton, understand these older supplies 
with one pass transistor can fail, putting overvoltage to the radio.  Until 
I can correct this deficiency, I'm reluctant to use the rig.  Unfortunately, 
this Triton is the older variety with the Jones plug, so don't own a cable 
to let me power the rig from one of my other supplies.

Ten Tec no longer sells the OVP kit.  I know the circuit is fairly simple, 
but evidently there are modules available commercially that perform the same 
function.

Would appreciate knowing what others have done to solve the overvoltage 
problem, wiring in a commercially available product is my preference.
