I had my great condition pro 3 on my bench adjusting the MOSFETs, I gave it a micrometer of a turn and they were reading pretty spot on...where I left the amp running half HR or so with no problems.before I put the lid back on I thought I'd give it another quick check,when I touched the mosfet leg with the multimeter clip (as shown in picture) it made a crack and quick spark.not sure what the damage is...could be a simple fix or could be a big fix 🤷.doesn't appear to be any scorching or damage anywhere else.i did switch it on quickly afterwards where it cut out after a min or so (protection mode).collection or
Can meet within reason.Happy for someone to Arrange their own courier.
