General Questions / Solder resin clean up?
« on: October 26, 2014, 09:33:50 PM »
Ok, I've been using Kester "44" rosin-core solder for a long time. But at times when I'm building a project with a white pcb or some other color, I'm not too pleased at the yellow resin that is left behind.

Do any of you use anything to clean it up? i've tried rubbing alcohol, but it seems to just spread around making the whole board sticky.

Is there a better solder to be used? I'd like my joints to be cleaner overall.


Tech Help - Projects Page / Taptation wierdness
« on: July 26, 2014, 09:48:56 AM »
Hey all!

Ok, so first time with the taptation chipset. I'm feeding into a de profundis, and it sounds great. The ony problem I get is tapping is somewhat funky... If I take too long to tap, it switches into basically 0ms delay (scale LED goes solid). Overall tapping seems a bit hit and miss. Is that normal for this thing? I've tried 3 different taptation chips, 3 different digital pots, and 3 different pt2399's. Same result with all. When I do get a good tap, the PT2399 is really close to the lighted tempo.

Anyone know where to source a knob like this:


General Questions / Suggestions for Clipping Diodes
« on: March 15, 2014, 11:39:58 AM »
I'm putting together a PCB that will allow me to dial in various clipping options in a typical symmetrical or asymmetrical clipping path. Also thinking about offering this as a project for sale to the community when I get it done.

I'm hoping you guys can throw some diode suggestions out there... I'm thinking about having 10 different positions for each diode in the path.

1n34a, bat 41, bat 46, etc....



Tech Help - Projects Page / Kingslayer crazy Squeal
« on: February 27, 2014, 04:25:32 AM »
Ok, So I just put together another Kingslayer -- and I'm getting a crazy squeal when I max out the gain settings (i.e. OD clipping on, turn up the gain and the tone or the volume) and I get a high-pitched squeal over the top of everything. other than that it works as expected.

I realized that accidentally used a 7660SCPA instead of a 1044, so I swapped it out, but no change. Is it possible that the 7660 damaged something? Should I replace the TL274 and the zener diode?

Thanks in advance fo rthe help.

Mods / Kingslayer with adjustable OD Stomp
« on: January 07, 2014, 09:42:07 AM »
So I was thinking it'd be nice to have the OD switch as a seperate stomp, sort of as a second stage. If I wanted to make the level of the clipping adjustable, could I just add a 100K linear pot to bleed the clipping to ground?

Tech Help - Projects Page / Kingslayer gain problem
« on: September 30, 2013, 11:04:10 AM »
Hey guys,

So I've built two kingslayers now, and they both sound great - BUT - the first I built was the buffered version, it has massive amounts of gain. The second is true bypass. It has hardly any gain -- the volume is at Unity at 12 o'clock and only goes up slightly when cranked.

Any ideas what gives? They are using identical chips -- is it possible my Charge pump is screwball in one? I swappled the TL274s and saw no effect. Haven't had a chance to swap the 1044's.

Anything else I can check?

Thanks for any help!
