@clearthinker - thanks for the kind words. It’s been a learning experience for me. I bought some of the harder to find Vertigo Swirls that didn’t clean up in the then relatively novel Audio Desk ultrasonic, and that took me back to manual cleaning and vacuum. I had to work on some of these albums. They were obviously not owned by audiophiles, but by "heads"-- deep prog rock from the period. I found that the combination of manual cleaning/vacuum/ultrasonic/pure water rinse
resuscitated these-- what sounded like "groove chew" (damaged record grooves from kludgey old turntable/arm/cartridge) turned out to be contamination. Some records were simply damaged and no amount of cleaning would bring them back.
I then took a trip to the Packard Campus of the Library of Congress- and spent the day with their preservation specialists. Had a blast. Got to hear Les Paul lacquers cut on a homemade lathe that LP used to make overdubs- this was before he got his hands on a tape machine. The sounds were visceral, especially the early, foundational tracks. I then started to learn a little more from archivists and spent some time researching.
Lots of people have contributed to this knowledge base, from Rush Paul’s article on DIY ultrasonic made easy, to Tima’s efforts to up the game on DIY, to Neil Antin’s engineering/cross disciplinary approach.
I still buy old records because I’m constantly discovering "new to me" music on records that were made back in the day, most of which have not been reissued or reissued well. I too have bought old stock. I run into warps--I did invest in the Furutech version of the Orb DF-2, which has been a lifesaver for me.
I’m at a point now where I’m just chasing special, obscure records-- I’m pretty much over the "audiophile" stuff- largely because I already have all those warhorses. I have been recommending Bobby Hamilton’s Dream Queen- unobtanium as an OG, but recently recut from the tape by Bernie G.
I got rid of over 12,000 records before I left NY. That left me with around 5,000 when I got to Texas, and since then, I’ve accumulated maybe another 1,000? I’m a big fan of some of the Tone Poets and think Chad’s Verve/uMe line is a good deal for folks who don’t already own some of those jazz classics.
I tend to go for early heavy psych/blues/rock (now called proto-metal). Lots of great obscure bands from the UK and elsewhere. These are not records I’ll find at my local stores. So, I’m buying from dealers or private sellers all over the world. It’s fun.
On the contamination, who knows what some of this stuff is. I cleaned one of those early Vertigo’s and orange gunk came out of the grooves, fouling my stylus. That record went back to the seller.
I don’t obsess about this, because I have a bunch of other things to obsess about too. Keeps me off the streets.
Best,
Bill
