Preview: Rubycon Black Gate™ F vs. Nichicon Muse | XMOS Capacitor Oscilloscope and FFT Comparisons

Update 7/15/18: I just stumbled across by far the most detailed document I have ever seen on Black Gates™ and it is by Jelmax (the creators of the technology)! See the 107 page PDF here: Blackgate_Tech_Note_Compilation.             Cable used between the FUN01’s Coax output and the Siglent SDS 1202X-E : […]

DSC1.Difference : Update on the DSD Dedicated No-DAC (DAC)!

I have been slowly working on this project  behind the scenes, without posting about it much (aside from on This is a “discrete” delta-sigma digital to-analog converter (DAC) developed by Signalyst (although, this wasn’t made by them). Their goal was to be able to convert DSD signals (digital equivalent to SACD) into analog while […]

“Help”: My Cornell Dubilier BF-50 Is Testing Open Circuit as Good | Note : Treble Bleeds Halted

I was using my Cornell Dubilier BF-50 (vintage) capacitor analyzer with all of the right things showing on the “Magic Eye” 6E5 (Philips JAN (Mil-Spec)) electron tube’s eye for leakage, short, and open tests. By the way, the BF-50 uses a 12A7 (Tungsol) electron tube for both rectification of the AC input and amplification. Both […]
