This is way off topic for the OP, and for that I apologize. When I removed the passive crossover components from the 845s, I replaced the OEM treble transformer, because that unit could not have handled full range input, and replaced it with a massive full range EI type transformer, with a 1:90 step-up ratio. So now the bass transformers, which work up to about 2kHz before pooping out, are in parallel with that full range one. I experimented with using the full range tranny alone to drive the 845s, but it doesn't have the cojones. The bass tranny is needed for good LF response.
Here we go again. I have used distilled deionized water + triton X100 + isopropyl alcohol forever in my RCM. Although it does a good job, I was eventually motivated to try rinsing the LP surface after a good cleaning with the above mix, because there was word on this forum and others that especially triton X100 could leave a residue. (This is using a VPI HW17 RCM.) I found that a rinse with distilled water, using a clean wand on the HW17, made a noticeable improvement in my results. Ergo, this suggests there IS a residue left behind after evaporation or in this case vacuum suction. I would guess that passive evaporation would leave even more of a residue than suction. I was a laboratory chief at NIH or FDA in those days, and I had access to lab grade chemicals for making the solution. (Retired now, so no such luck, but I still have some high quality ingredients left.)
What instrument did you use to measure electrostatic charge on your LP, before vs after the experiment with room air?
