Cleaned on an ultrasonic machine, play-graded with a $2K cartridge.
You did better than the advice you got here....
Yeah we found a HiFi store in gothenburg that was most helpful (Akkelis Audio). and they had some serious gear,
The stereo system we listened to sounded real sweet!. Very revealing, so the small amount of background noise is likely to be almost unhearable on a normal setup! the record played very well except for a couple o clicks on one side.
The ultrasonic cleaningmachine worked perfectly, fully automatic it took a couple of minutes and the record was as new, i would sure like to buy one and i can strongly recommend it to anyone who got the resources to do it! but it came at a whopping price of 2200 Euros........... So now we are really excited to see how much he will get for the record.
with a week to go the bidding is up to 795 british pounds.
