Supratek Owners Thread
As @isaacc7 mentioned,  Mick stopped making them back when Covid hit due to an extremely high backlog of Pre's need to be made.  I believe orders have since slowed down a little for him and I'd be willing to bet he would make or certainly consider...

I have found that a good 50hrs seems to open up the OPT's,..  I always hear a difference in the first hour as the unit gets hot and temps stabilize.   Tubes can be hit or miss with their own break in,..   some don't require much time and some do,....

@tksteingraber   You will hear a little crackling when the remote is used due to the motor interacting with the high gain circuit.  You should only hear it while the motor is turning the vol up or down (remote) though.  Should stop once you take y...

They do take a little time to settle in when new.   You'll notice a nice difference within a couple days (20-30hrs),.  Those Output transformers need a little juice running through them to open up.. The supra's also like to be at stable operating ...

Honestly @tksteingraber  I wouldn't worry about asking Mick to send replacement sn7's.   Your better off finding some good ole NOS USA (or new/current) ones from a reputable local (US) source and going that route.  Things take such a beating these...

depending upon the 300b tubes you have installed maybe,  maybe not..   you need to measure.  the dimensions of the GF tube are given at the site.

Congrats!  I have one here.   A very good circuit without doubt.

The XLR in is transformer based so yes, it is a true balanced input converted by transformer to single-ended for the circuit.    The circuit itself (gain stages) are not balanced.   The output is transformer based as well and able to truly balance...

@gryphongryph    Contact Mick and get my contact info.  I'd like to discuss your issue a little more but feel like we should take the convo off line from this thread.

There is a 'mute' switch, yes.   but you have to engage/disengage it manually.  Not automatic at startup/shutdown.

The original dual was adjustable on both channels.  His current version 300/SN7 is adjustable on the 300b. SN7 is only main VC.    @Gryphongryph ,  does the gain adjust the sn7 output ?   Regardless,  if your losing a channel when you engage it,  ...

The balance shift is slight.  The control is not implemented in the traditional style where it is another shunt to grd. in addition to the Vol. pot.   Mick does this purposely because there is less degradation to the signal but the caveat is that ...

The Chrome is plated over a copper chassis.   He used to offer a straight copper that was polished (pics on his website) but did away with it.  There is a ‘antique copper’ finish that is more a copper/hammertone type finish over a copper chassis. ...

Btw,..  the difference between the 2 is pre circuit.  Chard. hey s a traditional resistor loaded circuit, 2stage, direct coupled.   Cab uses some CCS load,  direct coupled as well.  Both are parafeed output as all Suprateks are.

Nah,.. you dont understand the PS, and how its built.  There is very little difference if any between the  chardonnay / cab PS.   The main PS feeds the tube regs which make it what it is and do the major cleaning/stabilization of the V feeding the...
