Record Cleaning Machine - Loricraft PRC-3 vs. 4?

Mike, I also have a PRC-4 Deluxe. I like it for all the reasons you mention, though I never use the reverse switch as I find putting the wand on the other side of the label accomplishes the same thing. My final pure water rinse for example is done with the wand starting at the outer groove (as you would playing an LP) traveling to the label and then from the label to the outer groove on the other side which achieves two things: a double dry cycle, one in each direction.

Could you explain how the more powerful pump works faster? I always thought the speed was the same (roughly 72 rpm) for all the models.

I also own a PRC-4 Deluxe and curious Mike in relation to speed.

Have you guys ever have any issues with the wand moving ahead "skipping" and not vacuuming a area because I have, I have tried what Peterayer mentions also on final rince and vacuum and found the second vacuum the wand sometimes just jumps ahead or goes right across the record.

If you don't have any of these issues what should I look for, my unit was brand new when I got it and I don't really see any type of adjustments.

check tracking force should be at 2.5 grams for vacuum arm.

Peter and David,

maybe it's between my ears about the cleaning speed being faster. i never had the PRC3 and PRC4 Dlx at the same time. there was 2 years between those 2 with just the Audio Desk. it just seems quite a bit faster with the PRC4......and since i'm happier i'm just going to skip merrily along thinking it's faster. :)

btw Peter, i want to thank you for your feedback on your cleaning process last year. since you posted that i had thought about changing and finally a couple of months ago i did. i'm also using that 3-step cleaning process, and you are right, it is better. thanks.

You are welcome, Mike. I have since added the AIVS No. 15 as a first step. It is another enzyme step and is well worth the time/effort. I also use two rinses, so the AIVS 3-step for me is actually 5-steps. Crazy, I know.

Dev, on very few occasions, my want skips about 1/16th of an inch about 3/4" in from the outside edge only when I do the first enzyme step. This happens about 1 in 30 times. I don't know why. I just redo the outer one inch and move to the next step. I think it might have something to do with the magnet drive under the arm base skipping somehow. Have you tried contacting Loricraft? I have not bothered.

Hiendmuse, I use zero tracking force. I find that the suction is enough to pull the arm to the LP and vacuum up all of the fluid.
