[Hallicrafters] Re: I'm Confused

[Rick Smedberg]

Dear Al;
I have a tr7 and had a simular problem, poor 10 meters then it smoked
while
i was trying to turn up the gain to get more output on ten.
I TALKED to the factory and got some advice. Check the predriver board
mounted on 
the pa heatsink. if it is the one with only two transistors try
replacing
the transistor q2202 with the same number only.  I am not shure on the
board
with three transistors but i beleve it something simular. than do the 
readjustment for balance between 10 meters and the lower bands.
variable resistor r2210.
if you don't have the instructions than i could copy you the pages you
need.
