The four trimmers provided for C32, C34, C44, and C46 are supposed to be
5-30pF ceramics but the ones supplied appear to be quite different.
They have a brown plastic type body and don't appear to be ceramic. I
can find no markings on the trimmers to indicate their capacitance. The
inside adjustment screw head is + shaped rather than a single slot for
use with a small flat blade screwdriver. All this makes it difficult to
set these trimmers to the mid-point as specified in the manual page 68
Figure 6-23.
So I decide to find their midpoint by measuring them before inserting
them, but came up with 20 -70pF which is a lot different from the
expected 5-30pF.
I don't think my capacitance meter would be that far out.
The other two 50pF trimmers, C21 and C23 are certainly ceramic.
I've checked various assembly photos and they all appear to clearly show
ceramic trimmers.
Can anyone tell me if these are a correct replacement?
Should I proceed to find the measured midpoint of these on the basis
that they are a correct replacement?
Thanks,
