I used to get a slight pop with powering on and off my VPI Classic and interestingly enough, an even louder (much louder) pop with turning on the turntable switch-but not the vacuum switch) on my VPI 16.5 RCM. I eliminated both inadvertenly by replacing my power cords on all my equipment. My old power cords were all inexpensive LAT cords and I seem to recall that several years ago I went about lifting the grounding cord on two or three of them, so the grounding may be a big part of the benefit that I obtained when I replaced the cords. My new cords are even less expesive-DIY made from Supra LoRad wire obtained from Madisounds. For those of you who don't know, the Supra Lo-Rad is very good Swedish made cable specifically made for AC power cords and is extremely well shielded by an aluminum wrap. So, I don't know if the VPI gear emits significant RFI/EMI that causes the pops, or if the grounding eliminates some form of electrical line induced noise, but I can say that the problem can be eliminated without changing out capacitors.
VPI motor popping noise upon startup/shut off
Hi All;
Has any one successfully filtered out, or stopped the popping sound commong from the VPI Aries Scout stand alone motor which occurs during start up and is louder during shut off of the motor? This noise is audible through the speakers.
The table is grounded to the Art Audio Vinyl One phono stage, and like all the front end gear, the power cords our shielded and have Hospital grade connectors. Also, all the front end gear is going into a Monster 3600 MKII power center, which is going into an APC Battery Back UP. This double filtering works great with the sound, and protects against our numerous lightning disruptions and brown-outs.
Perhaps there is a single recepticle power filter.
Thanks for looking
