Here is one of the many PM's I've sent about this. It should be pretty complete but this covers only the 2 tube models, not the 007t.

You use a normal multimeter set at DC voltage, the lowest voltage level (20volts or less). The amp is powered on when you do this with the new tubes inside. Never pull out tubes when amps are turned on. Only do so when the amp is disconnected from the wall. Leave the amp on for two hours so the new tubes can stabilize. You measure in the Stax plug on the front and here is a picture First you measure between + and - on one channel and adjust TVR1 and then put the multimeter between + and the ground post at the back and adjust TVR2. Both are adjusted for zero. They pots are clearly marked on the PCB for each channel. Be very careful inside the amp because there are some hundreds of volts floating around. I use a special screwdriver that is only bare metal at the very tip to adjust but plastic screwdrivers are also good. Below is the original instructions from head-fi posted by Kevin Gilmore in case I missed something: Quote: There are 2 pots per channel. One of them is the differential pot, and you put a voltmeter between The two output pins and adjust for zero. I believe this pot is labeled TVR1 For left channel voltmeter goes between yellow and green for right channel it is white and red The other is the dc offset pot, you put a voltmeter on either output pin and ground and adjust for zero. I believe this pot is labeled TVR2. For left channel voltmeter goes between yellow and ground, for right channel it is white and ground. You have to do this a number of times, and new tubes drift like crazy.

It's always nice to buy some more tubes so please let me know if you find any extra.

It's too bad the Stax Mafia does not exist. "Spritzer" is certainly well-suited to be a member of such an organization.

I can neither confirm nor deny that I am a member...

If there were a Stax mafia I think I would qualify as a member but you never know just how picky they are...

They do maintain some field agents, though, a couple of whom have already posted in this thread.

That's us in a nutshell. No dynamic driver has ever impressed me (speaker or headphone) like a good electrostat goes every day so we are locked away from all of those evil magnets...

We do poke our heads into the ortho discussion now and again so not all magnets are bad.
