Here's a little write-up on my efforts last night with CM1 serial 62-0023.
...........
I've sent an email to Enterpoint asking about the possible capacitor fix that applies to the first 50 boards, or complete RMA.
For those with 0000-0050 serial boards, John from Enterpoint replied a few hours after I sent the email (impressed!). They want to wait 2-4 weeks before doing any RMA on these as they may have a fix in firmware for them, and by then they'll have additional stock for RMA if required.
