The last few days ive had a problem with Jelco arm on my Techy.
The grub screw on the central stub had worked its way loose from the torque applied everytime i pushed/pulled the arm into its rest clip.
The stub had obviously dropped down so the arm was in a tail down position so when i tightened the grub screw i checked for VTA using a tiny bubble level placed on the cartridge housing, a finicky job but i was lucky enough to get it spot on in no time.
I was shocked to find the sound change dramatically much more toppy and less of the seismic bass sound i hear in the technics.
You have to bear in mind this is the first deck i have used for HI Fi duties, before that i used decks for DJ work and could never see the point in playing with VTA,
it never seemed to make a difference. I have a badly warped Art Blakey LP that i never exchanged because it sounds fine. So this is all a revelation to me.
The difficulty im having is so far it actually sounds fine but i have lost Bass,significantly. Im listening to Massive Attack right now and the highs are clear as a bell, well extended and dont sound harsh but the deep bass notes have thinned out almost as if someone has switched of the subwoofer.
Now i dont know wether to get the protractor out or play about with the VTA, neither jobs i particularly like doing.
Is this all part of the learning curve of owning a HI FI table? Have you all been here before and learned through trial and error to a point you could fix your settings blind fold?
Should i be using a test record for adjustments by ear? Do i have to take a week of work?
At the moment id rather chill out with the sunday papers an listen to a cd to be honest. Any support from AOS members will be gratefully recieved.
