From what I have read about what you can do with Phoenix psu you start at 100 volts and once the table gets to speed drop voltage down to 85v.
Hi Robert and all, well, I've just replaced the original TD146 16VAC with a TD145 220VAC Thorens motor. Just by looking at it I see it kicks in more vigorously and then what I expected was a slight fffsss
sound that I noticed instantly and a faint but present "knocking" sound. This last one disappears once the belt and platter is on. What the 16VAC was not doing either way. When music is playing it's not existent though.
Sonically, well the sound is tighten and speed in sound more accurate indeed. The first plays kinda brought the highs to high though. After some more dampening on the SME tonearm 4 pin external cable's connectors the mid and low basses came out more present, evener and cleaner. Then the highs and depth in sound lost some of their presence. And I did love them... I'll give it some time and see-hear how it comes to the heart of these ears.
Now I'm still awaiting the last part (still held at custom) to set my external PSU & tachometer unit. Once I'll receive it I'll install it all. After what I will make anew PCB for my 16VAC Thorens motor and then compare both motor fitted with the external PSU & tacho and see/hear which one I do favor in the end. And for the info, I'll have the Eagle and not the Falcon PSU from Phoenix Eng. that has to be pre-set for 230V and not 110V !
