Correct!

Ah I see it now! Nice one....

Any chance, guys, of a full-sized close-up screen shot of the whole PCB, and an arrow pointing at that particular bit, just to keep as a reference? The other pics are a bit small :)

Cheers! :cool:

Hi kcc123,

I see no reason why the SL150 power supply can’t be upgraded. There are three main power supplies to consider, 20v, 12v, and 5v and the possibility of individual stage regulation as well. The SR3-20 and the SR3-12 could be used to replace the 20 and 12 volt supply sections. The 5 volt regulator is fairly rudimentary and deals with the display electronics so should not be too demanding. However I would prefer to not to take on any more upgrade projects like this at present, until I have finished with the ones I am working on now.

Regards
Paul

Hi Paul,

Thanks!

Merry Xmas!

I think Mike was under the impression a few of the TS ones may have been fitted differently by mistake but seems all may have been fitted this way ?

Fantastic - that's exactly what I was looking for! :)

I opened my Techie up to check the 0V tag and indeed it had been placed on the top-right post (i.e. the wrong one) by Timestep. I re-routed the cable slightly and attached the tag to the correct bottom-left post. This cable is now quite short and just reaches the SR5 PSU with little to spare, just as I want it for least voltage drop. Things are sounding very good indeed.

I've now received a 4-pin Neutrik connector and will fit this next, to replace the 5/2.5mm PSU plug.

Quoi??

This is impossible... After all, we're talking about the WORLD's No1 Technics guru, no less!!! :eyebrows:

Yup, I can see the logic in that, and am sure that there are undoubtedly sonic benefits to be had. I'll be doing the same thing on my deck with the Kimber DC cable :)

Let us know how you get on and whether you can detect an overall sonic improvement after having carried out both modifications :cool:

Marco.

Nearly forgot: I've put a set of sorbothane Flatfeet under the PH PSU feet.
