A Tale of Two Arp Filters

Post by Voltage_Controller » Sat Apr 20, 2019 9:45 am

"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of ARP FILTERS FOR 5U!!"

Ok, I had planned this entire Dikensian thing for this post but gave up after the first sentence :lol:

I am looking at the two (that I am aware of) Arp 2600 filters for 5U/MU.

The MU AC version http://analogcraftsman.com/?product=ac2 ... escription

And the 5U MOTM panel and pcb set here: https://www.diysynth.de/pcbs-panels/product-58.html

My preference is the panel/pcb set, but I have a few questions:

Will the power specs work with my dotcom power supply? -> power 15/-15V ca.60mA

Here is what I think is the pcb accommodation for the dot com header, no?:

Does anyone here own (of have built) this version? If so, can you confirm the build is fairly easy? The pcb looks rather straightforward.

If you own it, what do you think? I am willing to hear feedback on AC version too, but mostly interested in the DIY version.

Are there any other Arp modules available for 5U/MU? I am specifically interested in the classic Orange and black panel graphics along with the circuits themselves.

I wish the DIY version was 2U width like the AC version, but oh well.

Thank you!

I heard from patrick at dsl-man.de and he confirmed he includes an adaptor for dot com so that challenge is resolved. Still curious if anyone else has this module...

yeah the STG is very appealing in that its 1U and I know suit's builds are top notch.

Yves Usson (Yusynth) has a DIY version of the Arp 4072 filter too.

My STP4012 VCF is based on the arp4012.
Jammie Logan designed it with me.
We used 4 layer pcbs and a potted module.
Cv resonance is done by an opamp and a vactrol.
I built 4 of this modules and few friends.

Grey with silver flakes edition is available too:
