My tonearm bearings were wearing out on my SL1210 MK2. I thought about selling it and going with the P6/Ania combo, but that was going to be very expensive. After speaking with with Kevin at KAB, decided to keep the Technics, and sent him my turntable. Once he received it, he gave me a detailed report on what needed to be done and what upgrades would be most cost effective. Main upgrades was a new tonearm with upgraded tonearm wiring, cardas cables, tonearm damper, strobe disabler, new regulator and a few other tweaks. I have already been using the PROS30 cart that I’ve had for about 9 months now. I have had it back for about a week now, and wow. The difference is just amazing. Immediately noticed the vocals are much more life like, highs are much more refined. I played a few of my favorite Neil Young albums and they sound so much more lively now. Very happy with this upgrade. I highly recommend KAB if anyone wants to take their Technics to the next level.
