Dave Sarge is the go-to guy for amplifier repairs in this area, the guy that knows electronics, tubes, and speakers inside and out. You know the type – if he can’t fix it, then it ain’t broke. So, I felt both disheartened and relieved when, after checking on the status of my busted keyboard amp, he began his response with “Well, I certainly will not be charging this on an hourly basis.”
Traynor K4 Keyboard amp
Apparently neither he nor the Traynor/Yorkville company amp tech in Canada has come across this particular issue of loud constant popping from the speakers whenever the amp is turned on.

(Cool, my amp is SO hipster).

So, whenever Sarge does get it figured out, I suspect there will be an addendum made to the Traynor K4 Service Manual, and I can feel happy that I was able to fund his latest opportunity to further contribute to the knowledge base of amplifier repair, and make the Universe a better place.

(For the record, I love this loud, aggressive, multi-featured keyboard amp and miss it terribly… It enables what happens on my side of the stage to be more than just support staff to the guitar-gods I’m fortunate enough to play with).
