Just testing out a new scope (OWON sds7102) in the lab today, decided to do some thing useful with it and compare the noise on the Aune T1 (original version) with two different 6DJ8 tubes.  Test condition: 1 khz output at 80% full scale generated using the Audacity software.   Here are the screenshots with volume knob set to output 2V (about half volume) and 3.6V (about 80% full volume):           The unit has dominantly 2nd and 3rd harmonics both about...
This includes the A/C adapter, and cable with short extension shown, the batteries don't seem to hold a charge any more.  I used it about 1 year.  Shipping from Waterloo, Canada
Selling my original E10 with the Wolfson / AD8397 chips. Original USB cable included.  Shipping from Waterloo, Canada.
Wow, they sold for $1425 I wonder who bought them.

Converts most audio amplifiers with 6L6s, EL34s, 6550s or 6V6s to EL84s without modification or rebiasing.   I have actually been using them in guitar amp, but they will work in any amp that uses the 6L6, 6V6 or EL84's and turn it into a cathode-biased class-A circuit running EL84.  Changes the tone to a very mid-range rich detailed sound. They retail for $59 for one. The pair of adapters comes with the matched Sovtek tubes shown.   
Haven't got the time to build another one. Discovered these in my drawer so it's better someone else build it. $25 shipped to Canada gets them $30 to US.
I would also say this is a great value.  It is a really detailed, yet forgiving source for the money.    Just some tube rolling impressions this evening:   EH 6922 tube (supplied with delux version) is a smooth all-around tube.  The bass is deep though a little loose, and the treble is a little forward.  Some of the mid-range is a little grainy and recessed, but still rich.   Amperex Holland tube circa 1965 (pulled from old Tektronix scope, datecode 'Delta...
Just a 2-day left bump..   these were highly desired by the way, the sound is really impressive for something so cheap and simple!   And... can you even buy made in Japan these days for less!?!?
