Anybody have experience with the Dennesen Air-Bearing Linear Tracking Tonearm (ABLT-1)? I've come across one that I'm told by the current owner "doesn't work." Trying to get more info, but I suspect that - assuming there are no parts missing - its just the air pump is not functioning. The only source I could find online is that a 1.5 psi pump is needed:
https://www.gammaelectronics.xyz/audio_07-1982_dennesen.htmlI currently have an ET-2 air-bearing tonearm, so I figured I'd try that pump on the Dennesen to see if I could get it going.
Doesn't anybody have experience using and/or restoring these? I've tried to locate information online and not finding much detailed info or discussions in other forums.
Assuming I could get the tonearm working again, is it even worth the effort (and whatever cost)? From the lack of info online, I'm assuming since information/discussions about them online is scarce that didn't perform well and were mostly abandoned?
