| "Cleaning" Vinyl Makes It Worse Not Better! @tomic601, Probably a friction stir welded tank my team built….ha. One million linear inches of weld without a defect… definitely NOT trial and error… That's impressive. The tank was an open honeycomb design. When they explained what they w... | |
| "Cleaning" Vinyl Makes It Worse Not Better! If Neil were to buy a Vacuum RCM and a US RCM and used his magic to invent a technique for them I am all ears. I would be very interested in that, but trying based on his description, with no practical experience, I hesitate to go down that rabbi... | |
| "Cleaning" Vinyl Makes It Worse Not Better! FWIW the basic rules for UT are as follows: The power to produce cavitation is proportional to the kHz, so a 120kHz UT needs more power than a 40kHz. For ultrasonic tanks, the bubble diameter is inversely proportional to the kHz, so a 40 kHz U... | |
| Record Cleaning Machine ~ Ultrasonic vs. Rest According to the RCA vinyl record patent 1498409551006799538-03960790- the PVCa copolymer equals 96.2%. The remaining ingredients are varied in purpose and specified with reasons for each additive and its concentration. The heat stabilizer is de... | |
| Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition Sorry I am late to the party but here are some clarifications and some information. There is nothing wrong with using tap water for rinsing so long as you do not allow it dry on the record which is why you immediately follow with a DIW rinse. ... | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? @flash56, Parts Connection Parts Connexion services Sonic Frontiers components and does improvement mods on some. I am quite sure they could refresh your SFP-1. | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? If all you are looking for a SUT, then suggest MovingCoil (erhard-audio.com). He took over for K&K when Kevin got out of the business. Erhard builds with Lundahl SUTs and there are a number of different versions (kits can be fully built for ... | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? Icon appears to be very elusive with giving any kind of definitive answer. In this review of their PS3 Icon Audio PS1 Mk. II All Valve Phono Stage — Audiophilia Icon expresses their view of step-up transformers stating So, that is why IMHO (and O... | |
| Does anyone have experience matching an Icon PS1 MKII with a Soundsmith Zephyr MIMC Star? Soundsmith specially states a 10:1 ratio SUT is perfect for their low-output MI such as the Star - Transformer use with Soundsmith MI/Fixed coil designs | Soundsmith (sound-smith.com). A 10:1 SUT should yield 470-ohms load to the cartridge. Howe... | |
| Objective Data re: Record Cleaning The weight I was referring to was of smaller coupons that represented a record contaminated with a known amount of soil only to measure cleaning efficiency - not the entire record. Otherwise, there are lab techniques that can be used to measure no... | |
| Ultrasonic Record Cleaner 40 v 80 v 120 kHz @jwr159, Be advised that inexpensive UT tanks like the Vevor can be very noisy; enough to drive you out of the room or wear hearing protection. Also, you will want to buy new power supply that can slow down the motor such as Amazon.com: Belker... | |
| Objective Data re: Record Cleaning When measuring weight, the samples are measured to <0.01 mg and particle counts below 50-micron are normal noting that the nominal width of the groove (at the top) is 50-microns. Otherwise, Parks Audio phono-preamps Parks Audio (parksaudioll... | |
| Ultrasonic Record Cleaner 40 v 80 v 120 kHz @jwr159, If you read the book, Chapter XIV XIV.4 Record Spacing, and XIV.6 Record Rotation Speed you should realize that they are spinning too many records too fast. Otherwise, the 4875 tank is 40-kHz and 160W while the CS6.1 is 48-kHz and I be... | |
| Objective Data re: Record Cleaning To objectively measure the efficiency of a cleaning process, you always start with a known contaminated standard and then measure how much of the contaminates were removed. This is generally accomplished with parts of a specific area and weight w... | |
| Ultrasonic Record Cleaner 40 v 80 v 120 kHz The Audiodesk_Pro is a very low powered UT device. The manual Audiodesk_Pro_Manual-2018-7-Inch-Kit.pdf (galibierdesign.com) indicates an overall power of power 90W (which include the rollers) and a volume of 4.5-L which at best yields 20W/L but m... |
