Sooooooo....
I decided to be brave and face the consequences...
And , the verdict is that , I hope that my other TT is serviceable (it was about 8 years ago!) and its motor is steadier than the one that I use now
OR
I'm gonna need a new TT...which is as a LOT of dough cause I'm a "Linear tracking" kinda man and getting a decently priced one is gonna cost me a LOT!
Any suggestions for a decently priced LT TT would be appreciated...
Problems...quite a few, but an especially worrying one...quite a bit of "wow" on the motor, discovered while playing back the square wave.
Frequency wise, it's fine , but the channel separation goes to hell in a handbasket at around 10K (!)- and , curiously enough, there's more bleed from R to L that from L to R.
Here is what it looks like:
Until 1:40 - 4 sweeps L, R, L, R from 500 Hz to 50K
At 3:30 - 2 Reference tones on each channel (look at those harmonics..and crosstalk!)
At 7:55 on both channels a 350 Hz Signal recorded at increasing peak amplitudes of 50,60,70,80,90 and 100 Micrometers for lateral modulation monitoring (a LOT of fun...!!!)
At 9:05a square wave Form 2.7 duty cycle 3:7 (below)
So there...
But, let's give it a break...it's a Technics from the early 80's!!!!
I'm sure it has seen a lot of action!!!
Comments are , of course , welcome...please make them as nice as possible...
