Thanks, guys! I've got some coming - and (unfortunately) after "magically" fixing that Yamaha module I've got several more pro audio units to repair. The worst of the batch is a Behringer 32 channel mixer with many issues; more of those Wong Ding capacitors. It's a major project to disassemble it, and there's over 1,000 of those caps to replace; no point in just doing the 20 or so bad ones, get them all now and have years of good results in the end. Sigh; it looks like it'll take a week or so to fix this one. Fortunately, replacement caps are dirt cheap here in Asia, and the owner is willing to pay well for good workmanship. Looks like I'll be a pro audio repairman for the next few weeks.
