SERVICE PROCEDURE-2
DTR-7.8
When a power amplifier of certain channel is broken and goes into Protect mode, the following parts in the channel
must be replaced at the sametime, because these parts get damage in most cases.
NACLA-9063, NACLA-9066 and NACLA-9068 are electrically and mechanically full compatible with each other,
but idling readjustment is necessary.
These units include the following componets in each channel driver stage, which are extracted from components listed above.
NACLA-9064, NACLA-9065, NACLA-9067 and NACLA-9069 are also electrically and mechanically full compatible
with each other, but idling readjustment is necessary.
