Anyone familiar with the RF Concepts Max 45 2m amp? Its supposed be rated
for 45w in 150w out according to the manual i got with this one. I can only
get about 110w output.
Years ago i had a similar model Mirage amp that someone else had readjusted
for 100w output instead of 160w output. And i remember adjusting something
inside, trimmer caps in the pa if i recall correctly.
I opened this one up and see one large compression trimmer on the input side
of the amp after the T/R relay, and one next to each transistor as well. I
can't find any service information for this model online, as a matter of
fact i can't find anything for this model online. Anyone know how to make
adjustments to this model? I would like to see it doing at least the rated
output.
The previous owner said it was too much power for him and he turned it down
to 100w according to his wattmeter, mine shows 110w. Unfortunately he
doesn't remember what he had to adjust to do that since it was years back.
Thanks in advance...
