Hi Paul,
I cant tell you what it sounds like 'cos I made a slight blunder and touched both probes of my multimeter together when I was adjusting it.

New regulator to be installed.
The instructions were none existant-it said 'assemble as diagram' but the diagram was very poor. Anyone above numptie stage should put it together in an hour. Took me about a week. It didn't tell you that the regulator should be bolted to the heatsink and separated by a mica washer and didn't mention heat compound.
Parts are all well known and the circuit board is a beefy 2mm thick.

... so I'm looking forward to reports after you installed new reg ,-)

Well my home made power supply has been running with my Murata regg'd 7520 (thanks to Puffin for the repair) and I have to say the results are stunning. Just to complicate matters I have also switched to the AD826 op-amps so I can't be certain the improvement is all down to the power supply.
The improvement is across the range-vocals, soundstage, dynamic range, its like having a new system.
If you have gone as far as fitting the Murata's then you NEED to get a decent 15v supply.

Jerry,

nice to hear. Do you run the PS kit you mention in the other PSU-Tread? Any mods on the kit done? I ask as you mention it's a little bit noisy ...

Cheers,

I have to say that I cannot notice any noise but I am looking forward to seeing (and hearing) what the Teddyreg does.

Note also that I built a PSU for the Caiman using the SuperTeddy reg. Sounds very good indeed.

I did this...
Turned the thing to most clockwise... Reads 15.36v should I turn it down to 15.00

MartinT · 25-06-2010, 19:31

I think you're safe up to 16V, but don't blame me if it explodes! How does it sound?

**The Vinyl Adventure** · 25-06-2010, 19:34

Dunno .. Not tried it yet..
Cheers for pointing me to this thread Martin ...
Any more firm comment on the voltage issue... I'm trying to avoid fire here
