3 SR6-SONY, Serial to Parallel Converter
INSTALLATION for AMPEX VPR-2
Wire SR6 pin #9 to AMPEX pin #31, Ground.
Wire SR6 pin #3 to AMPEX pin #5, Record.
Wire SR6 pin #4 to AMPEX pin #1, Play.
Wire SR6 pin #5 to AMPEX pin #15, Stop.
Wire SR6 pin #8 to AMPEX pin #20, Shuttle Command
Wire SR6 pin #6 to AMPEX pin #16 through 27K ohm, 1/4 Watt, series resistor.
Wire AMPEX pin #4 (+12 Vdc) to AMPEX pin #16 through 100K ohm, 1/4 Watt series
resistor.
The value of the 27K and 100K resistors can be adjusted for a desired shuttle speed per
the following:
When pin #16 voltage is:
Î 5 volts, the tape shuttles forward.
Í 5 volts, the tape shuttles reverse.
The further away from 5 volts, the faster the shuttle speed.
The closer to 5 volts, the slower the shuttle speed.
