Moderators isaac42 Posted May 23, 2014 Moderators Share Posted May 23, 2014 No response to this in the FX forum. Guitarist says the power supply is going out on his RP355. Calls for 9vac. I have a 12vac supply available, but I wonder if that would be safe. I have used 12VDC supplies on 9VDC units in the past, knowing that solid state electronics have a bit of tolerance for supply voltage. But that was my choice, on my gear. 33% voltage increase might be too much for his pedal. Does anyone know if 12vac would work or not? Link to comment Share on other sites More sharing options...
Members WRGKMC Posted May 23, 2014 Members Share Posted May 23, 2014 The right ones only $11 here. http://www.rakuten.com/prod/hqrp-ac-adapter-power-supply-cord-for-digitech-rp255-rp350-rp300a/247726310.html?listingId=270750498&scid=pla_google_HQRP&adid=18165&gclid=CLXb4ez3wb4CFUMF7Aod6VUAJQ Why take a chance on blowing the bridge rectifier diodes or overloading the filter caps. 12V is only three volts more but I found its the current rating that the most important item. Even between different 9v supplies you can go from weak operation to a bad hum if the current rating isn't correct. I personally wouldn't complicate the matter. By the way, I have fixed old wall warts before, either replacing the jack or cracking one open to fix the open wire right where it meets the unit.

Moderators isaac42 Posted May 24, 2014 Author Moderators Share Posted May 24, 2014 Personally, I don't think there's anything wrong with his PS. I think it's his cord. But he asked me, so I thought I'd throw it out there. And I'm not taking any risks. It's his unit, and he'd be making any decisions on the matter.
