switch expert mod help needed
Hi. I have this reel-to-reel remote control. Well, remote for the 70s in that it plugs into the back with a 15 foot cable. Hah! See attached pic.
I would like to modify the buttons.
The way it currently works is this: If you hit the PLAY button it will play. If you hit the STOP button it will stop. FF and REV self explanatory also. Now to record you must hit REC and PAUSE at the same time, then they light up. When you are ready to record you then hit PLAY and it starts to record.
I would like to modify it to this : No FF. No REV functions. No buttons. Only 2 jack inputs. If I send in a control voltage into jack 1 it will play. If the voltage into jack 1 is 0 it will stop. If I send in a control voltage into jack 2 it will record. If the voltage into jack 2 is 0 it will stop the record.
Does anyone understand this schematic and how to modify it? See pic attached. I also have the rest of the reel-to-reel schematic, but I don't think we need it.
FYI: When reel-to-reels record, I believe the erase, record, and play head are activated. When it is only playing, only the play head is activated.
