Hello;
I've noticed that I needed to use a very high level to load sounds "From
Tape", much higher than with the original boards.
C4 is given a 0.047uF ceramic in the parts list; on the original boards it
is 470pF. Exchanging this cap made loading "From Tape" much easier.
The mistake may stem from the service manual which has two caps marked C4;
the "real" C4 (470pF ceramic) is the one parallel to R5; while the one in
series with R28 is C5 (0.047uF plastic film).
