Default Is anyone familiar with the JBL Synthesis pre-amp?

Try shutting off the unit, disconnecting it from the wall outlet, and
letting it sit, "unmolested", for at least 24 hours. There is a slight
chance this will fix the problem.


I have to say, though recently it had become worse, it has done this
ever since I got it a few months ago when it had been siting on a
friend's shelf for some years (though he reported that the last time
he used it, it did work properly so I will try your suggestion).

Hmmm...

Does the unit uses a lithium coin cell for backup? Just wondering.

The fact that it worked before it was put into storage, doesn't prove
anything about whether it would work several years later.


No, there is no lithium cell but there ARE some curious white (what
look like) pot controllers by the L and the R of the phono connectors
which dont figure on the manual for this unit. I wonder what they
are? And I wonder if they contain the solution to the problem of the
apparent dry joints? I am sure there is no way of spraying Tuner Wash
into the pots under them if pots they are but I wonder if they have
just become dirty?
