[Drake] T-4XB--no output

[Paul Ellis]

What a great group (again!)!!  The responses are as right on and as fast as 
the Saab car mailing list I'm on. Fantastic community here!  I got the rig 
working right tonight--it was a combo platter of things gone wrong.

The 680 ohm resistor that Garey talked about was indeed the culprit 
(discovered after using the R-4 antenna input directly to measure signals) 
Once that resistor was replaced, it worked... but not as it should.  I read 
the manual again and checked the linked transformers; T-6 was off.  I 
measured and adjusted that transformer and tweaked the trimmer caps (with a 
plastic screwdriver, as to prevent the destruction of the same resistor I'd 
just replaced), and all is good in the T-4XB.

Thanks again to all who helped me today!

best 73s,
