Hey James.  I've read about the mica disease and am dreading experiencing it with my HQ160 as well!  What I was wondering was if the signal was getting thru T2, and very little was getting thru T3, what made the OP go back and take a harder look at T2??

If a signal is getting thru a preceding stage, but not the stage under examination, why would you go back to the preceding stage?  Could it have been that the output signal from T2 was not strong enough to be processed by T3?

I'm working on an SX-24 that the RF signal is getting thru the RF amp, but I'm not not getting anything thru the oscillator/mixer/detector.  The 6K8 tests fine (don't have a spare to replace it anyway - as yet (I'm going to order a couple of them just to be able to switch it out and have a spare).
