Just finished getting a Zenith AM/78 player combo
working, replaced the filter and all other caps and
now it sounds great. Phono spins perfectly (with the
normal clanking) but it needs a new needle. This is
the Cobra head tone arm, AES has replacements. Now
the dumb question, how the heck do you get the tone
arm up far enough to access the needle. It only raises
a few inches and as far as I can tell the two screws
underneath adjust the balance and limit how high the
arm raises when changing records. Do you remove this
second screw to release the arm?

Norm and Don, this is the set I asked about the dial
lamp voltages on, you were right they were 6.3v #47s.
They seem a little dim, but the voltages are good
throughout the circuits, so I guess it's o.k.

Thanks to anyone who can answer this embarassingly
dumb question.

hi Scott, usually there is a clamp at the base of the
tone arm pivot..enabling you to remove the tone arm for such
repair. Remember when re-installing you may find that the
tone arm may not land on the starting groove. You will
have to possibly re-adjust the clamp a couple of times.
