Paul,

Outstanding. Not to mention the improved measurements if a balanced source is used since you are cancelling the 2nd order harmonic with your build. I figure for an 8 ohm load... you should get about 30 watts at 1% THD? Output impedance should rise to 0.36 ohms or a damping factor of 22.5. I hope you enjoy this build for years to come.

Best,
Anand.

Paul, and others who've designed faceplates thicker than 10mm, did you CNC the front panels yourself, or are there shops out there who will machine larger pieces? Front Panel Express and Modushop both max out at 10mm. Does anyone have recommendations for other machining services that can work with 15 or 20mm designs?

I have the opportunity to get a Sony ta-5650. The owner says that the light turns on when powering on but it does not give out sound. Beyond opening it up are there any ways to indicate that the VFETS are ok?

Thanks,
