Re: A not so standard SSS002 build

Incredible build! Impressive.
I wonder how many hours it took you.

Good to know :-)

Re: Steel String Singer #005 build

I can't imagine that it will have a noticeable impact as the high pass filter cutoff shifts from ~ 7 Hz to 15 Hz (edit: 47n to 22n).
Well below the guitar frequency range.

Re: uTracer (Micro Curve Tracer)

Hi Martin, yes, I'm running Ronald's GUI v3.12.6 I measured the voltages directly at C13 and C18 versus cathode. All the measurements were done in continuous mode, i.e. anode/screen directly connected to the reservoir capacitors C13 and C18. I have tried uT JS and see the same. What puzzles me is th...

Re: uTracer (Micro Curve Tracer)

I've got some weird phenomenon going on with my µTracer 3+. Calibration of Va and Vs is fine (measured in continuous mode between C13 and C18 and cathode). When I run the µTracer it indicated lower voltages than what why DMM measures (the same one that was used for calibration). The first table show...

Re: Steel String Singer #005 build

I had these made through a local company here in Germany. It set me back a whopping 220€ and it isn't even painted haha! In hindsight I should've probably looked for someone that would be able to powdercoat and screenprint but taking into account that this is only for a single build that's okay for...
