In order to correct the volume level changes which take place when
recording directly from these models, we suggest making the following
changes.

Refer to Figure A and Cassette Schematic.

1. Add 22K (1/2 or 1/4 watt) resistor across record terminals (one
end on G6) of SW-IC to keep C6 polarized.

2. Add 100 ohm (1/2 or 1/A watt) resistor in series with diode Dl
(one end of C15) to prevent overcharging of C15 on beginning of
large signals,

3. Operate each unit for 5 minutes in the record mode.

4. Test cassette by recording a high level signal for a period of

one minute.

NOTE

If Large amplitude of level changes are observed, replace C6 or
return cassette unit to factory for replacement.
