the one you are looking for. Remove this filter board from the
motherboard (if you installed the optional edge connectors) or
unsolder the F E T from the filter board (with power off). Inspect the
board closely by consulting the manual AM 204 "Galaxy Voicing":
Possible problem: A stop does not produce a sound.
Possible causes: Faulty F E T on the filter board, missing
components or missing wire jumpers on the filter board, connecting
pin (s) at the wrong location(s)in hard-wired systems.
Trouble-shooting: Compare the board with the assembly
instructions of AM 204.
Possible problem: No stops produce any sounds.
Possible causes: Short circuit between the foil trace "Su" and the
neighbouring foil pattern on the motherboard G P 1. Faulty IC 1 on
GP1. Faulty wiring of the audio cable from the pin "Outp." on G P 1
to pin " E 6" on the preamplifier.
Trouble-shooting: Remove the connector from plug 2 on GP 1.
Stick a pin into each of the two connector openings where shielded
cables are attached. Hold both pins with one hand and "borrow" an
audio signal from the tone generator with your other hand (G 2
boards). N o sound = trouble in the wiring (consult wire list). If you
get sound, the problem is located on the voicing motherboard G P
1. Remove it from the lid and inspect the narrow foil pattern very
carefully.
8. Check the sounds of each fixed stop with the description
below, while playing the lower manual.
AM 075 (Part)
Note 1: Minor variations may be noticed since the tone generator is
not set to its correct pitch.
Note 2: Do not jump to conclusions if a particular stop does not
sound exactly as you envisioned. The speaker placement and the
tone control settings may not be matched yet or maybe you are
playing notes on the 61note keyboard which do not exist on the
real-life counterpart of the simulated instrument. (We do not know
either how a clarinet is supposed to sound when played
[hypothetically] at the normal pitch of a Piccolo.)
