Hello,
Would you mind sharing a bit of info?....
On an MD20A why would you not get a full 2 v.P-P. reading while adjusting signal? swapping scales remedies this. Is it just from a crud buildup in the coil on the head?
Readjusting pots does not bring it up to spec.
Alarm triggers randomly.
Is there any source to get more insight into how this scale works as Sony doesn't divulge much.
Doesn't look like something to wear out.
Also, do you have replacement heads?
