Supratek Owners Thread

Thanks for the reply Johnny, interesting points you make, unbelievable the hum suddenly disappeared last weekend and has not come back yet, although I have not had time to listen since Sunday evening, I have not done anything to the system for at least a week before, where I have been trying everything I could think of, like the fase on the pover cables, tried 4 pairs of different rca cables and 2 pair of xlr cables, also unplugged various other units like dac, Mac mini that is on separate mains, but nothing helped, then suddenly it’s gone, I am a bit perplexed of it all, Mick is sending me an other power supply, which I am grateful for as it would make me feel more comfortable with the purchase in the long run.
When I got it, there was no hum at all, although I thought the power supply could be more quiet, the hum came after 1-2 weeks.

I need to clarify a thing, when using the 300B output the gain is okey, although I have to turn it way down, it sounds quite good after using it exclusively for over a week now, but, I still like the 6SN7 output better, if not for the gain.

Maybe a better pair of 300B tubes would give me more clarity while keeping the warmth.

Yes, I am not a fan of the biblical cord between power supply and pre, seams unnecessary stiff and unwieldy, a softer cord would be preferable, will check both connections if, or probably when the hum comes back, as I suspect it will.
Now I hear only a slight hiss from the speakers, but I have not tried it with the 6SN7 output since the hum disappeared, unfortunately I am swamped with work all week and probably weekend too, so no testing until sometime next week.

There is a big difference in sound between a standard 300B and say a TJ Full Music meshplate.Almost like a different preamp.With the meshplate you get beautiful airy treble,much better timbre and a much more holographic soundstage.If you have heard the difference between say the really good Dynaudio speaker models and the next tier down it is that sort of difference.The difference between good and great.

On the Cab Dual Mick recommended to stay away from the mesh plate tubes, was it the current draw?

I have used meshplates in  my 300B single Cabernet for years with no problems.
