Did some more work on the lenco. I pulled the motor and rebuilt it, as I dug out my build notes for it and something was missing. Yes i am a sad twat who keeps notes on these things, comes in handy down the line though.
Turns out that the recon motor I put in it to replace the completely seized original never got any attention, i just dropped it in for some reason.
Notes said 'feels ok, no drag, rebuild? ' then nothing.
Noise floor has dropped nicely, and the annoying tick it had developed has been sorted too.
I demoed it for a chap in January who subsequently ordered the one with the roksan tabriz arm on, and it was obviously performing under par at the time. I really should stop neglecting things..... Much betterer now
While I was at it i degreased the motor spindle, platter underside and idler wheel tyre with a product called elbow grease (no really). I use it because its a solvent free degreaser so it doesnt attack the rubber idler tyre or the machined surfaces. Makes a huge difference to pitch stability to do this as it stops the idler losing traction.
Used it on the truspeed deck too on the subplatter and the motor spindle and it worked on that too.
Its amazing how much crap comes off.
I also took some time to play with the setup for the at1100 arm. Dropped the arm height slightly to bring the vta to the right angle, and set the tracking weight to the 1.4g that audio technica specify for the at150. Had it set at 1.6 as that seemed best in the mayware, its better at the suggested 1.4 in this arm.
Then played records all day
