[pcb+panel] yusynth steiner parker filter for eurorack

Post by TimoRozendal » Fri Nov 06, 2015 4:04 am

intro
Hi, I am Timo. I am relatively new here, but I really enjoy being part of this community and learning as fast as I can (with the time and money I have available). I already offered pcbs and panels for the Fonitronik ssm2044 filter and I also did the software for the Falafular Corny Rhythm.
But now, I am happy to offer you pcbs and panels for the Yusynth Steiner Parker filter. With permission of Yves Usson (and commission to him with every sale).
(btw, I would be grateful if somebody knows how to get in touch with Thomas Henry, i have also made similar eurorack pcbs for a bass++, but know I am looking for permission)


I wanted to make a versatile filter for my system and decided to make one based on this design.

Changes from original design:
- no switch but separate buffered input for every mode (LP,HP,BP),
- lowpass input is normalled to highpass and bandpass, so you can e.g. transition smoothly between high and lowpass with the knobs
- 'tweak' resistors are replaced by trimpots
- added decoupling capacitors for ic's
- added a flexible footprint for the matched transistors, I tested it with THAT300, AS394 (Letvian LM394 clone), 2n3904 and BC547 (I don't hink the original 2SC1583 will fit)
- provided panel pcb, so no wiring required

The inputs have enough gain to overdrive a normal signal in the filter.
The resonance is still a bit untamed and chaotic and not so useful for melodies (plus it won't self resonate at low frequencies, a known trait of this filtertype)

offer:
PCB set: 10 euro
Panel: 7.5 euro (this is made of 2mm thick pcb material)
THAT300 chip: 2.50 euro
Shipping: 3 euro for pcb only, 4 euro for panel+pcb
