I'll start with a bit of a story....
I'm in the midst of trying to illustrate that a Technics SL-1200 mk2 that I purchased refurbished (and have had serviced), is experiencing problems.
What I've been doing is recording the Ortofon Test Record that plays a number of sweeps and tones alternating between the left and right channels, and looking at the resulting channel separation and levels.
To demonstrate that the problem is with the SL-1200 and not the record/my system/etc. I also captured a recording of the record test with my Technics SL-10.
The setup:
Record Player (SL-1200 / SL-10) -> ifi Zen Phono -> Behringer UCA202 Audio Interface -> Record via Quicktime -> Audactiy to view
Results:
SL-10
Even with a $40 budget elliptical cartridge (Audio Technica 85EP) the SL-10 looks to have good channel separation, and level match.
(Please note, this isn't me recommending the 85EP cartridge - it has a terrible static pop problem - verified with 2 cartridges and multiple turntables)
What I noticed was seeing how much "micro" variation there was in the signal.
What do you think, is it the small adjustments of the motor as the cartridge moves across the record, or is it the performance of the cartridge?
SL-1200
Pre-and-post service, same problems with poor channel level match, and "bleed" through into one channel.
Perhaps an azimuth problem? Or a cartridge problem?
