Rick's going down the right road. I too suspect the PA is kaput but I've been 
fooled before.

I recall I was working on a trition 4 and had very low RF output. Everything 
seemed to be just fine. but nothing I could do would pop the power up to 100 

Long story short.

one of the low level drivers that produce 1-2 watts had a run of coax that went 
to the predriver. during assembly a screw punched into the coax and over time 
worked its way into the it shorting out the cable. No drive----no output.

So, remember, nothing in, nothing out.

Since you're not drawing oddles of current, most likely the PA output 
transistors have opened.

a fubar PA from a junker trition maybe a lot easier to install than fix the old 

just a thought

Good luck
