Vacuum Record Cleaner Rreplacement


I get most of my records from from garage sales and such, and they are typically pretty dirty.  My record cleaning protocol is to run them through the vacuum record cleaner then the ultrasonic cleaner.  If they have fingerprints or mold I’ll put them through the Neil Antin’s method.  I’ve done it this way for years with good results.

Unfortunately, my venerable Music Hall WCS-2 needs a new cleaning wand and I’ve been told from numerous sources that the parts are no longer available.  I started the hunt for a new vacuum cleaner and found a suitable replacement.  Before I pull the trigger, I wanted to determine if I really need a vacuum cleaner if I’m using the ultrasonic.  I’ve used both cleaners in succession more from habit than any practical reason, though I’ve convinced myself that the vacuum cleaner gets the big chunks off first and the ultrasonic does the fine, deep cleaning.  I don’t know if this is true or not.  

I’d like to know the thoughts of the group.  I’m more than happy to buy another vacuum cleaner, but could always put that money toward something else if it is not needed.  

Thanks in advance for your help.

I have been following this thread for some time now with interest.  I have a VPI 16.5, an Isonic 40kHz US and a Degritter.  I use the Degritter primarily as a final rinse phase with 30cc of ethanol in the bath of distilled water.  I change this every 10 records or so. All records start with a fresh water rinse with label protectors in the sink, followed by drying with tiger cloth, then immediately on the VPI where I use AVIS #15 with Osage brushes with 3 rinses with distilled water. I let the AVIS sit about 5 minutes and then rinse. I do other things during the waiting part, so about a minute of time is used.  If its a dirty record (not new), it will then go in the Isonic next with Tergitol (along with 2 other lps) then rinsed again on VPI and then into the DeGritter. My rationale is to do the heavy cleaning outside of the US treatments using the Degritter as a cleaning rinse only.  I feel pretty confident that the amount of particles left in the DeGritter bath is minimal.   I used to use the VPI as the final step but had a hard time dealing with the static charge left on the LP surface from the brush.  In a well lit room, I could see dust motes dive bombing the surface of my new clean record before I could sleeve it. It does take a well lit room to see this by the way. Sooo, here's the million dollar question-how do those of you who finish with vacuum drying eliminate the static charge and the dust Kamikazes?

That hiss you noticed with the LOMC cartridge when not being played may very well be the line stage tube in the preamp (assuming your preamp is not solid state)

It was a high-end dealer's demonstration system, and the phono stage was a solid state Musical Fidelity component, feeding McIntosh power amplifiers of some sort. Obvious hiss is not something I had ever experienced in my own systems and I went back to the dealer to confirm whether the hiss was real. 

I really was not concentrating on the electronics the first time, because it was at major promotion for B&W loudspeakers.  I just happened to notice that the source was a linear tracking deck (Holbo) which impressed me, so I arranged to take some records for a private audition.  That's when I really noticed the hiss for the first time.

My guess is it is quiescent electronic noise amplified by the high gain needed for LOMC.  I ended up buying a very high output DS Audio optical cartridge instead, so hiss is only of academic interest to me at the moment.

Those Kamikazes appear from nowhere (or from me and my clothing?) after air-drying, but I can usually gently blow them away.  I play the record before sleeving it, and use a conductive brush before play, but ...

I've got another million dollar question.  Does the mere act of playing a record create new electrostatic charges?

The triboelectric effect creates electrostatic charges when dissimilar insulators are rubbed together.  Diamond and vinyl are dissimilar insulators.

Do these charges create any audible noises?  Or do they attract charged dust mites which in turn act as audible obstacle courses for the stylus?

The answer to your first question was answered many years ago - Phonograph Reproduction 1978, James H. Kogen, Audio Magazine May 1978 Audio-1978-05.pdf.  However, simple carbon fiber brushes unless connected to a ground will not dissipate static from the record.  If there is a static charge, the record will have a negative charge, and particles are mostly positive charge, so they attract to the record.  Absent a static charge particles should not drop on the record since the air current will draw air down and then across but above the record - Laminar Flow Over a Spinning Disk | Ansys Innovation Courses.  Additionally, particles deposit/drop from the air at different rates depending on the particle-size - CACR25_FINAL_LR.pdf.

Antinn, thank you for citing that 1978 issue of Audio magazine, in which in the section on ES charge, it is clearly stated that friction between stylus and vinyl does not cause significant ES charge to accumulate on the LP surface. Maybe that will finally satisfy RB.
