Human comparator's ARP 2600 Clone

[pbotsaris]

Hej Alles!

I'm going to write in English because my Dutch's still terrible (but I'm working on it!).

I built a ARP 2600 clone a few years ago (http://build.thehumancomparator.net/). It is mostly working but I have a few problems with clock bleed to the oscillator pitch, LED drives for the sliders LEDs currently not working (and I think these two problem are related) and one of the Oscillator card (4027) is not working. The clock bleed is actually a design issue that came with revision 1 of this built and I have addressed it accordingly installing the regulator boards to the VCO's.

It also need to finish up a couple things such as connecting the reverb tank to the inboard driver as well as the 2 speakers and multiple jacks.

I have been very busy and unable to properly troubleshoot this thing and my knowledge in electronics is fairly limited to do so. So I'm looking for a professional that could help me finish this project in Amsterdam or anywhere in the Netherlands.

Please let me know if anyone is interested in working on this.

Best,
Pedro

Bring it to Saint Eric in Dordrecht (he's the nr 1 Arp Specialist)

It should be noted though, that some of the issues are specific to the TTSH 2600. Did Eric build any of those?
There are a few people here that have built TTSH's I believe,hopefully the'll be in touch.
I let go of my PCB, frontpanel and parts, too many things I didn't agree with (the way the LEDs are connected amongst other things).

I've built two v1 TTSH's (with clock bleed fixes) and a v2.

The bleed is a design issue but the regulators are not a full fix, as it will still bleed into other parts of the circuit (most notably the filter, so you'll hear it in the resonance).

Feel free to contact me.

Thanks for the reply guys. Yeah, but the bleed is too intense with in the VCO's, there must be a problem somewhere other than design issues. Etoin, I'll send you a PM.

thank again!
