[TenTec] Corsair I gone bad!

[Stuart Rohre]

Look over the wiring and parts carefully for smoked components, int the 
stages where you heard sound and saw smoke.

You are looking for popped open capacitors as a first priority.

Also examine resistors for shifted values, and smoke damage.

This might have been a transitory event, where a connection popped off a 
terminal and shorted a voltage temporarily before burning out the 
shorted connection.

But all the possible issues 'should' have left clear smoke damage 
interior of the area where you saw smoke come out.

Use a high intensity light to see things like changes in color code on 
resistors, or dark areas under the chassis.

The Corsair is a pretty rugged and durable radio, well worth fixing. 
There should be several expert repair types on this list who might offer 
related failure experiences.

I have operated a friend's Corsair, and heard his tales of near 
overloads.  Instead of fuses, the Corsair uses a fast operation circuit 
breaker on the external Ten Ted power supply.  But it usually survives.
