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 : […]
Six Rubycon Black Gate F capacitors are on the way for the FUN01 (SU-1 Clone). Stay tuned to find out how much of a difference they have over Nichicon’s MUSE series.

Don’t see this very often, even in classes they didn’t have one of these that had cracked the wax. First two pictures are with a 50mm lens. I noticed the wax had broken in a circle around the end and if I could pull the end right off, the solder was already broken and […]

I have been slowly working on this project behind the scenes, without posting about it much (aside from on ComputerAudiophile.com). 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 […]
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 […]
Well I currently have about 8 pages written of notes, thoughts on head to head Burson Play vs my custom ES9038Pro DAC. In the end it ended up being very close, which is why I was volume matching. One time I forgot to match the power amp back down and we got a […]
This single loose solder ball (could have fallen inside the enclosure at any point) might explain all the problems I had with getting the DAC to lock on to any audio signal. It would be a great job if it wraps up the issues. Stay tuned to find out if I was right! […]
Hallman Labs first official products for sale will be treble bleed circuits for guitars! When you dial down the volume on your guitar (with any pickups) the high frequency is rolled off sharply. The treble bleed counteracts this rolling off of the highs by bleeding high frequencies directly into the potentiometer output leg. Thus acting […]
