Hi All
I recently picked up a new Project a Roland RD-150 circa. 2002, The main control board was smashed to bits what i have now rebuilt after many hours and swearing at it
Now The SMPS is playing up with a nasty buzz and crackle - initially it was putting out a low voltage (under load) what was cured by a re-cap
Roland have discontinued support for this model 8-10 years ago so spares are non existent, I do have the service notes but the SMPS is a Daughterboard and is not covered, i cant even get the specs
Part numbers on the pcb
KPC1694V-0
B104
F8044PA
Part numbers From the service notes
SWPS1
A1DU2L3B104
02127512 (Roland)
Input 100-240v
Output +15, -15, A GND, D GND and +5v
As far as i can tell the DC to DC transformer is a - EEL19-H, Dual primary, Dual secondary (5v and a -15, 0v, +15 centre tapped) I can't find a off the shelf replacement from any UK or US supplier
Any help appreciated
