Title: Ph-1 Schematic
Post by: Blackie on July 22, 2005, 08:54:49 AM
Hi All! :)

Im new here and i have a little problem with my Ph-1. I have noticed that some wires are cut on the board, but i have no idea how to repair it. Is there the possibility to have the schematic or a repair manual for this phase?

I know the Roland society don't send schematic ecc.


Thank for your helps.

Blackie,
1) Does the Phaser work at all right now? If so, is there a problem with the sound?
2) What color/how many wires appear to be cut?

I have the PH-1R in pretty much mint condition, but can take a look inside to see if there are any similarities.

Puretube, thanks for the link!

Bucksears: Inside the pedal there are some solder places without wires. They are 1, 2, 6, 10 and 15 (its localized at the center of the board). I think that the place number 10 is for voltage because there is a diode just after it. 7 and 4 are connected with a pot ( the value is 1M C). 5 and 9 for the led and 3, 14, 8 are connected with the other pot ( 100K B).

The pedal dont work right now. So i have no clue about it.
