Wrenches, My customer has a circa 2001 Pulse PC250 with a faulty PM-60 circuit board TC-750, REV D2 (the microprocessor U1 has v2.5 and v1.01 written on a label on it). Does anyone repair or have replacements for PC250 PM-60 circuit boards? If not, what do you recommend? Thank you in advance for your help. Joel Davidson
