Maestro - PS-1
I've seen lots of info on the Maestro - MPF-1, but never anything on the PS-1 / PS-1A / PS-1B phaser?
Anyone have a schem? Know anything about the footswitch?
It has 3 switches on top for different set speeds, and originally came with a footswitch that connected through a 6-pin Molex type connector on the back of the main unit — it’s pretty rare to find one used still with the footswitch though.
I know Ronsound builds one. I can’t imagine it’s that hard to do. Any pointers where to start?

The scheme is pretty simple (I have a PS laying here)
I'll check it!

bump...I can guess how its wired but, would love to see a close-up pic of the guts as well. I'd like to try to duplicate the look of the switch a little better than the ronsound unit.

Today I'll make some pics
All three switches are SPST switches that make or break a connection. The blue switch switches the FET on and off thus turning the unit on / off. With all other switches off the unit has a 'low' speed.
When the other swicthes are turned they turn the middle / high speeds on and off. The unit ramps up which is quite nice!
The remote connections use a 6 core wire to get all connections there. The layout of the unit is:
Grey is the wire from the blue switch and need to be grounded to turn slow / unit on / off
Black is the ground
Red is the fast switch
Blue is the middle switch
Yellow is direct from a point after the diode bridge
White is the point red and blue needs to be connected to.
Yellow is for the lamps I guess. The circles in the picture are the dents of the connector so you can hook the connector only one way up.
Pictures follow!

Many thanks for the info. I don't suppose you have a footswitch that you could snap a pic of the internal wiring of would you?
Thanks again!
Thanks again!

Thats an interesting hack...looks like someone had it screwed into another unit of some sort. What I'd like to see is the internals/wiring of an original PSFW-2 for the PS-1/A/Btube-exorcist wrote:Here is a "remote panel" for you:

I guess it is just a DPDT that AND connect the 2 wires needed AND connect the lamp from V+ to ground.

I guess the switch(es) connect the (12V)-lamp(s) from AC (pin 6) to ground (pin 1).Bernardduur wrote:I guess it is just a DPDT that AND connect the 2 wires needed AND connect the lamp from V+ to ground.

Thats what i'm thinking, I'd just like to see Maestros implementation & layout of the footswitch.I guess the switch(es) connect the (12V)-lamp(s) from AC (pin 6) to ground (pin 1).

Her is the chance for an original footswitch:

could you post those pictures again of the footswitch? I'm trying to repair one at the moment. Thanks!Bernardduur wrote:Today I'll make some pics

are the similar color wires in the footswitch supposed to go to the same colors on the plug in the unit? - i.e. red to red, blue to blue.
You said:
"Grey is the wire from the blue switch and need to be grounded to turn slow / unit on / off
Blue is the middle switch"
I'm confused. So does the blue wire in the enclosure go the blue wire in the footswitch? Or does the blue wire in the footswitch go to the grey wire in the chassis?
Wires in the footswitch I have are: red, blue, white, green, black, and what I guess is grey but looks more like another black. The obvious black does the lugs on the footswitches, the Greyish is where one of the poles on all the indicators attach.
The pink lines are the Black, Green line is the Greyish wire for the lamps.
Green wire is the OFF switch, Blue - middle switch, Red- fast switch.
