RK - but it is very noisy and does not pass your stylus on a stationary record test.
...the old dreaded stylus on a stationary record test with the system volume knob cranked to hear turbulence and hum test.....
Air Bearing linear trackers everywhere that depend on clean consistent air delivery cringe at the thought of owners subjecting them to this test.
Its bad enough if they have not been set up to operate in a straight line evenly. But being subjected to a partner pump that is not so great is un-imaginable.
Some of the worst arm/pump relationships I have heard of don't even relate to the quality of the pump itself but its placement. There are some owners in the southern US where winter does not exist. These owners place compressors in their garage (not climate controlled) with a long line going to where their stereo is in a nice climate controlled room kept at 72 degrees F. The garage where the compressors starts air delivery can be anywhere from 30-40 F in the winter at night to well over 150 degrees inside the closed barn on a hot summer day with wildly differing humidity. Imagine the changes to the air as it travels down 100 feet of tubing.
RK - I will do the compliant CW arm and spring test once the proper compressor arrives.
I look forward to your impressions Richard.
