請問有哪些牌子的 DC Power 適合 Antelope Trinity 使用

Trinity 個說明書資料:
Speakon NL4FX socket
DC, 12VDC +/- 1VDC, 15W

同埋 NL4FX 插頭既接線可以在哪裡買到?

- Kingrex MKii PSU (12V output)
- TeddyPardo 12V psu

Both are around HK$3000

Internal and rear pictures are shown below. I think Kingrex's internal wiring is more tidy but TeddyPardo's case can provide better EMF shielding.

As the Nagra PLL Preamp that I am using has an external power supply unit with 12V output, I have been searching for a better alternative PSU

Nagra PLL preamp's PSU has fewer capacitors compared to Kingrex and TeddyPardo PSUs.

u may write to paul hynes ..... a ac shunt regulated supply should cost around gbp700 (after shipping) not cheap of course. but top notch stuff.

IMHO Kingrex's psu is overpriced. The AC-DC circuit is simple/mediocre.

A similar linear psu with better R-core transformer is made by Teradak at much lower price.

However, if cHings want the best performance, TeddyPardo or Paul Haynes are the ways to go. Their AC-DC conversion circuits are special!

Thanks for CKKeung c-hing's advice. I noticed that Teradak PSUs are cheaper.
