Hi,

because I need to change the PA transistor at my FDK 750
I have to adjust the ALC and APC.
I have a electronic copy of the service manual
(You can find it at
http://www.geocities.com/gw0tqm/fdk/p014.gif)
but I don't understand how to adjust the APC
and ALC.
Maybe there is an error in the description of
the "A.P.C adjustment".
Should I really turn RV4 to change the APC?
(because there is no DIP Point at all when
changing RV4) Is RV3 meant?

And where should I measure the ALC voltage?

Thank you
