today I had the opportunity to cut again with the Neumann AM31 with Ortofon DS 501 cutterhead driven by a GO 511.
I'm experimenting with old lacquers, that I had cut 5 months ago with good results.
But tonight I got a very annoying squealing noise in the cut, that got worse the closer the groove was to the center.
I recorded a little bit with the noise, and some random reggae stuff dialed in after a while. LPI was too low, which results in a few skips and the recording ending in a funny loop.
you can listen to it here (couldn't embed it properly, sorry!):

Can anyone tell me what this noise is about? Wrong feedback adjustment?
feeling stupid.......
