Preamp Deal of the Century

Wondered if anyone had experience of older Suprateks, circa 2000? Much stiffer psu than my Syrah with tubes as follows-
psu - rectifier 5U4GG, 2X 5881/6L6 & 2x 6x4
line is 2x 5881/6L6, 2x 6H3n-E, phono is 2x 6GK5 & 2x 5842 ala Syrah.

I already own a Syrah and bought this older pre used as possibly an upgrade. A biy tatty looking (well used, surely a good sign).
Quick response from Mick as to how to rewire to 240V.
Soundwise - gorgeous on both line and phono:
but - it does not have anything like the gain of my Syrah and whilst the cd just manages to drive my Audiopax to usual listening levels (requiring a good hike on the volume compared to the Syrah), the phono as per the Syrah needs a few notches more and runs out of steam.
Full volume on vinyl is just not loud enough.(using my Koetsu Black so my zxy Airy at 0.24mV has no chance)

Suggested the 6H3n-Es are the problem but since that's what it came with?
If the amp has lower gain than the Syrah and not suitable then more fool me for assuming all Suprateks were pretty high gain >> but if anyone can at least confirm that it's the correct tube complement or suggest a way to increase the gain I'd be well oblidged.
From pin outs I cannot find any tube which could replace the 6H3n-E to give more gain. I can't believe a hint that these should be 6H30s as I cannot see how these could possibly be compatible if it functions with the 6H3n -
but I'm not remotely tube literate so who knows.

Any comments re talk to Mick - he's a busy man & both my Soopies were bought used so we'll assume there's a limit to the man's patience & not stretch it.

Thanks Simon

has anyone got the pre-amp yet? I tried to find more information, but the website is down

jaguarcondor:

are you referring to supratek preamps? plenty of people have received them. i just sold my chardonnay in favor of mick's reference linestage, the cabarnet dual. the supratek website appears to be up and running to me. try here:

Good news---the glare problem I've had with my Supratek Cortese preamp seems to have been eliminated. The preamp paid a visit to Kevin Covi, who told me he was certain he found the reason for the annoying overemphasis I was hearing in the mid to upper midrange. It appears his assessment was correct---a faulty operating RIAA capacitor in the phono stage. I got the unit back today, and after having listened to a number of my "test" records for assessing my system's sound, I found no evidence of the glare unless it was actually on the record. We all have our favorite listening test records, and are well aware of their positives and negatives. In the most constructive sense, what I've heard so far coincides with my previous listening experiences with these records before I had even purchased the Cortese. I'll need more time of course before I can safely feel I'm fully settled back into relaxed listening, but I'm certainly feeling I'm getting back on course. Thanks especially to those of you Audiogoners who, with your support, wished me well. And, of course, my considerable thanks to Kevin of Supratek.

Hello Opus88,

Glad to hear that things are back on track for you.
