Supratek Owners Thread

@nymarty you can try loosening up the volume control and recentering it in the mounting hole. Other options are a DACT or Kozmo but I don't think you have room for mounting internally of you want remote volume.These volume controls are bigger than the original Alps which your pre amp came with.

Nice to see the thread come alive again.  
The remote volume pot has been scratchy from day one for my new 2023 Cabernet.  If I move it quickly up and down a few times by hand it stops making the noise using the remote until the next time it gets turned off then on.  Doesn’t seem to be an issue for me unless it starts progressing.

I have had a handful of NOS tubes become very noisy and/or then go dead.  Common in my tube experience.  I have not found a new 6SN7 that can match the good NOS tubes.  Some like the Elite Linlai E-6SN7.  I tried a pair and did not care for them.  Very detailed and too solid state sounding and just didn’t pull me into the music.   I prefer the warm full encompassing sound.  A few fav’s are Raytheon ‘50’s 6F8G flat plates, Melz ‘50’s 6SN8, Sylvania ‘50’s 6SN7 GTA military shorty, heavy chrome down side with T-plates.

@nymarty   The motor in those is noisy from an emi standpoint and generates some hash in the circuit when it is engage.  Once the vol. is set though,  the motor is not doing anything so not generating the noise,..  you could probably find a different control that is quieter when driven but I doubt there would be a big increase in SQ from the different pot,  just less noise when ramping the vol. up/down.   The Kozmo's are nice but wont fit.  For what it's worth,  every Supra I've had on the bench exhibits the same noise when the motor is engaged.  Just the nature of that particular control.

@evank  Thanks!  System is looking good.  Did you move?  Are you going to CAF?

@tksteingraber  Thanks!  The noise isn’t much of an issue and only happens with remote, so will just ignore it.

@jslateiv Thanks!  I’m going to DM you about something else when I have more time. Really appreciate all the help.

@nymarty moved 3 months ago to Tarrytown. Also my Aric pre makes a boop boop sound when I use my remote. Its a Kosmo.
