Motorola ts907 low hv

Well, regardless of what tag they put on that subber, I would imagine that any adjustment
is to boost, or decrease output so as to change the level of signal available to the IF
section, not really the same thing as gain.....

Well, If you get something through the system directly from the TV's own tuner, that
is a major improvement, and big steps forward! And if that's the case, you should
definitely forget about feeding anything to the video test point, and work on the
battery AGC test point, and possibly even think about weather or not it's worth
the gamble of turning the trap coils to see if you can get more signal through.
But remember what was in that IF alignment video from this morning, you
have to remember each coil is peaked for a different frequency in the
full bandwidth that needs to make it through that section.... So
peaking one wrong will cause more problems....

Also if you are really getting a overloaded picture one minute, and a weak looking
picture the next, then you need to figure that one out.... Possible intermittent....
You may need to figure out how to clean the tube sockets & tube pins in a
really effective way..... Seems like you are getting closer to fixing this
one! And to do it before this thread hits 100 pages would also be
way-cool!!
