Looks first class, enjoy.

That's so nice looking and well-built it's sick!

Thanks you all for your very nice Comments!

How much current in the HV regs? I saw big sinks.

I cant stop looking at this. I think I will have to enlarge the photos and see if I can measure any hundreds of a millimeter in deviation between the twisted pairs/triplets. Absolutly top-job rclourenco!

Last photos of my implementation: The Supply Chassis!

Final result: Incredible clear #D presentation, dead quite with virtual zero noise on the speakers (even with your ear deep inside the mid/woofers).

I am very happy, the final result is really impressive.
Thanks to all (Thomas, Ale, Kevin and Rod) for your strong help and support.

Hi Rui,
Glad to see that the effort paid back and it sounds as good as it looks! Congratulations for such a fantastic build.

In place of Salas SSHV2 shunt regulator I want to use CCS+gyrator but Ikoflexer (thank you) told me that I need to feed the primary of an output transformer through a capacitor of the maximum quaility (parafeed), how much capacitance be rated having in mind that I use Lundhals LL1660 as OPTs?

How much current in the HV regs? I saw big sinks.

Running at 600mA each, I had the sinks, they fitted the board, and both Supertex and IRF devices are attached to it. Nevertheless it runs completely over specs and almost cold!

0.6 A ???

BTW, once again congrats, fantastic build!

(parafeed

Parafeed, why? What is your 1660 gapped for? I think 26 at 5 mA takes almost PP gapped 1660 without saturation.

I don't know, I'm newbie so I haven't idea, I'm asking?

Lundahls are wired ALT Q 4.5:1

Hello,

Just almost done gathering parts for my build. My PSU chassis is a little narrow so I include a pic(1st pic)here. The main chassis has the CCS/Shunt Regulator on board. I am a little worried about the cramp/tight layout I have on the PSU chassis. All trafo without covers, SS rectifier-filter boards, and capacitor banks will be mounted on the underside of the top plate of course. Any comments appreciated, thank you.

An externally hosted image should be here but it was not working when we last tested it.

Hi Rui!

Congratulations. Looks awsome!

Not necessary to run these in parafeed

Thank you Thomas.

Maybe you know what gap you have?

PP, 10 mA, 18 mA ore some special?

Thanks Staffan I bought the txs to Thomas, I think are SE Line Output 16mA.

Thanks Staffan I bought the txs to Thomas, I think are SE Line Output 16mA.

Then margins are definitely on your side. No PF for you

The mA are printed on the label...
