Leader LFM-39 Wow and Flutter Meter

Just received the unit in a very well packed double box, thanks again Lee.
I'll test it when I find a new power cord and how to wire the transformer to 240V.

Changed the power cord and modified the wiring to 240V.
It turns on, nothing exploded so next step will follow soon to tests with function generator, w&f tapes and calibration compare with WFgui software.
 
Just received some components from Mouser, changed six capacitors (two 330µF from the power supply and four bipolars), cleaned the switches with KF F2, works much better.
Next step will be changing the other capacitors and the calibration (20 trimpots that's gonna be funny).

And they probably all interact with each other to double the fun :-)
 
Before replacing the other capacitors (if really needed) I did a test with WFgui with the Technics RS-M95 and seen the ANT's tape has the perfect speed and the lowest w&f compared to an original Teac MTT111.

ANT (and it was a cheap version with off specs fr section):

Values on the LFM39 seems to correlate, I'll test again after some hours of run.
