  1. Well, it was $48 shipped, but got it the other day. Still figuring out how to use it. Here is an ARM processor, LQFP-100 package, soldered in. I had the alignment perfect; it moved slightly when I was tacking down a couple of corner pins. I'll go thru and verify with my Fluke.

  4. I am starting this thread for all that are or will be building JoaMat's mini T2 to share information, ideas, thoughts and experiences. The attached schematic is an updated one .The resistors in the BOM are thick film ones and can be replaced with thin film ones for likely better outcome. The power supply requirements for this amp are +400VDC, -460VDC (EL34 output stage), +220VDC (6922/6DJ8 front end), +15VDC, -15VDC (servo, cathode current source) and 6.3V filament supplies for the 6922/6DJ8 and EL34 tubes that can either be AC or DC. I also plan to use the +15VDC for the CPC1117N high tension delay. EDIT (Feb. 2020): updated schematic and BOM (Thanks JoaMat!) Note: PCBs pictured below are of older version. miniT2 v22 schematic.PDF miniT2 v22 BOM -Date_2020-02-16.xlsx

  8. Don't worry too much about the offset 20-30V voltage. It will not hurt your headphones at all.

  9. A few things: Offset and balance voltage will settle as the amp warms up. Are these voltage measure when the amp was cold or warm? IME, high DC offset usually caused by poorly matched tubes. Swap the 6SN7 tubes between channels. If the high offset follows the tube, replace with better matched tube(s).
