Now I've heard it all.

Furthermore, JP is a godsend to all of us (not just Technics owners) who admire the finest direct-drive turntables of yesteryear (sorry, Lone Ranger fans). I have a Victor TT101 that I bought cheaply, because it was "broken". For 3 years thereafter, I searched for someone who could fix it. Two really respectable guys gave it a go, but without success. I was beginning to think of the TT101 as a doorstop, when I came upon JP's MN6042 thread on DIYAudio. I contacted JP, and he agreed to take a look at the TT101. What he eventually found was a tiny crack in one of the PCBs that was intermittently interrupting the circuit. The crack was nearly totally covered with solder, so even harder to detect by eye. Once he identified this flaw, by logically tracing the circuit to see where the failure was likely to be occurring, it was no problem to fix. This all came to a head about a year ago, and my TT101 has been operating flawlessly ever since I got it back from JP. Kudos. It's a great turntable.
I also own a Mk3, also with Krebs mods. I bought the MN6042 PCB from JP but have not had him install it yet, because my own Mk3 was NOS when I got it, and the OEM MN6042 has never given me any trouble. But I know the Mk3 will work even better with JP's substitute circuit installed. Thanks for your report, K.
My chip failed about 6 months ago on my SP10mk3. JP was nice enough to provide details on how to bypass the chip so the table was up and running again.
JP sent me a new chip a few weeks ago.
I am taking the table and chip to the tech tomorrow. Not expecting the table to sound better - but you never know.
Should have it up and running again hopefully within 2 weeks.
I got my SP10mk3 back today. @lewm - you will be glad to know the tech replaced all the caps, as many were leaking.
he fitted the new MN6042 chip - thanks JP
he re-calibrated the table
and finally cleaned and oiled the bearing - in excellent condition he said.
Its back in the system, functioning perfectly and sounding great
Now what is blowing me away is this incredible, unassailable energy and drive. This table is unfazed by anything. I can hear and follow complex rhythmic structures like never before. And it has the huge soundstage and incredible detail to go with it. Massive, perfect-pitch bass. I’m loving it!
After living with JP’s FA6042 chip, I fully agree with kmccarty. It has brought performance up several notches which I did not believe it would. the bass energy, drive and control is incredible.
A must for SP10mk3 owners IMO.
