[TenTec] Fried Titan

[K6JEK]

I cooked my Titan I this afternoon.  I managed to route the output of 
my homebrew AM transmitter into the Titan input when the Titan was on 
and ready to amplify.  It seemed to think that 300 W carrier with 1200 
W peak was more than it wanted.  POW, smoke, dark.  Not much smoke, 
just a tiny bit.  It did blow a fuse but when I replaced the fuse, the 
grid current meter pegged on power on even before the B+ kicked in.

I'm now poking around on the bias board where there seems to be a fried 
1/4 W resistor.  It will be grand if that's all the damage.

Any advice?  Have any of you ever done anything this witless?
