All bands??
Does RF TUNE peak? In the 'right place'?
PLATE should dip around 4-5 on most bands.
Also, as 'everyone knows', that the first thing is to go through with a screwdriver and tighten all
grounding hardware. The mounting FEET of the small boards are almost all ground connections.

I now have my R4A back ,thanks to Lee"s Kc9cdt, fine work its doing a great job. Now the T4X,
Rebuilt the supply AC-4 ,heath kit board, came out fine. Fired up the T4x today,set the bias
current then followed the tune up procedure ,function switch to TUNE, advanced the gain to .15
amps , turned the plate control to dip the meter ..... nothing happens, meter stays same. There is
a TINY dip when the plate is turned fully clockwise ,but VERY small dip. Have not had the case off
the t4x yet,but of course the seller said it worked fine the last time he used it.
sure could use some guidance on this. only other facts, supply is 100% on all voltages, t4x going
into a dummy load and testing is done with the t4x not connected to the r4a.
thanks
