| Precision Aqueous Cleaning of Vinyl Records @mijostyn,No arguments that maintaining cleanliness is critical, but I have found as I stated in the paper that even new records benefit from initial cleaning, the pressing plants are not clean. Maintaining cleanliness is addressed in Section VI,... | |
| What to upgrade to? @bobheinatz,FYI - Soundsmith has most of their upper line cartridges on sale 25% off, https://elusivedisc.com/search?search_query=Soundsmith. A nice benefit of Soundsmith is their ability to rebuild the cartridge to near new many times at a fract... | |
| A Soundsmith Re-tip Believer @millercarbon,Not to go off track from this post, but this relatively recent article adds to the discussion of the cantilever/mass and what Peter (Retipper) has discussed about a benefit of his moving iron (MI) cartridges - "Vibration analysis of... | |
| End-Game RCM thoughts/advice @fzman1956, A quick review of Degritter shows some issues. The 120kHz frequency is very effective for fine invisible particulate 10 microns and less, but will not be very effective for larger particles or degreasing (if on the record) that is req... | |
| What to upgrade to? @bobheinatz,Some thoughts,1. Does your Lenco turntable have all the latest mods - see discussion high-endaudio.com/RC-Lenco.html. This will likely not consume much of your budget but could improve what you have. The SME V is such a high perfor... | |
| Thumbs up for ultrasonic record cleaning @tomic601,Jim,I use the Record Doctor Clean Sweep Brush https://www.amazon.com/Record-Doctor-Clean-Sweep-Brush/dp/B07M92LY78. The bristle diameters are not so narrow that they will deeply penetrate the groove - so there is very limited risk of re... | |
| Thumbs up for ultrasonic record cleaning @tomic601,As far as my tech manual, it took a bit of turn, and it now stands at 54 pages. The manual cleaning procedure is not very long, but I am adding a lot of details of the rationale behind various steps, cleaning agents and rinsing and I ex... | |
| Thumbs up for ultrasonic record cleaning @slaw Woops, misread your post, 5 weeks is not bad. You may want to check the chemistry with the shake test I discussed. Also, Versa-Clean specifies that the cleaner is mildly alkaline pH 9.75. You can easily monitor the tank pH with an inexpe... | |
| Thumbs up for ultrasonic record cleaning @slaw Some other thoughts,If you have been using the same tank of water for 5 months without refreshing the chemistry, the 'chemistry' of the Versa-Clean is likely long since exhausted and the tank water may be acidic. Water at room temp and just... | |
| Thumbs up for ultrasonic record cleaning @slaw,The activated carbon filter 'may' remove the surfactant that is in the Versa Clean, and that 'could' be the reason for the water clarity. As far as the cloudy water, that could be the build-up/accumulation of very small (invisible) particle... | |
| Direct Drive vs. Idler Drive vs. Belt drive @atmasphere,WRT to platter mats, the concept that materials cannot absorb/attenuate vibration is not correct. Very thin viscoelastic materials can absorb surprising amounts of vibration - the energy is converted to heat. This article is an excel... | |
| Problem with preamp volume control RV,Thank-you for the thank-you :). It was about a month ago when a similar item came up, but that time it was a Bryston amplifier that like the Benchmark had a selectable sensitivity, and the simple flip of a switch yielded similar success. Enjo... | |
| long lasting cart @chakster,Error noted. However, the $1150 AUD$ includes a 10% tax that is deleted if selling to US, so the USA$ price drops to about $625, and with $35 express shipping = about $660; hard to argue with that price :). Not sure if the stylus retip... | |
| Problem with preamp volume control RV,The Benchmark AHB2 has three different sensitivity (gain) settings - there is a small toggle switch on the back - see your manual pages 8/9 or download https://cdn.shopify.com/s/files/1/0321/7609/files/AHB2_Manual_-_Rev_G.pdf?6581480924542235084. | |
| Problem with preamp volume control @almarg,Unless the inline attenuator adds capacitance, the added resistance 'may not' be that bad for a MM cartridge and could be good, https://www.tnt-audio.com/sorgenti/load_the_magnets_e.html. But I will defer to your experience with these att... |
