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
