Blue Lantern Re-Releases one of their First Modules, the Steiner 10Stage VCF

Blue Lantern is re-releasing one of their first modules, the Steiner 10Stage VCF, based on the Steiner Synthacon filter [see the update below for their first]. There are currently only eight listed for sale via this auction.

Details from the listing:

"Model: 10 stage diode based vcf. Influenced by N. Steiner's synthacon vcf. This is a re-release for me.

width: 6hp

depth: 1.5 inches, less than 2 inches clearance.

current: soon, tba.

Controls: Cutoff, Rez, bi-polar attenu-inverter FM knob, CV knob

What does this do?
This is an analog filter that uses a 10 stage diode core influenced by N. Steiner's synthacon vcf. You get Low pass, Band pass, and High pass inputs. All of them can be used at the same time to mix different vco's. The band pass section is what really makes this filter shine.

Some blue lantern improvements include dc removal on the rez circuit, jfet power coupling, and precision trimmers for cutoff and rez.

Through hole polyester film capacitors were used for the filter.

Does this filter make all the screechy warble like all the other Steiner VCF's out there?
It can if you like that, but I ship it out tamed and very musical. There is a 25 turn trimpot on the back where you can fine adjust exactly how far you want to push the feedback resonance. This design I have does not contain the common dirty pot troubleshoot most people complain about. The inputs also have a switch jack design to quiet any input jack not in use.

If you missed out on the first generation modules I released, here is your chance to see what all the fuss was about."

Update: I asked Blue Lantern what their first module was and they had the following to say:

"The first commercial module was the 6hp Diode VCF, and then the 6hp LM4250 VCF. I have to mention Shawn from Analog Haven for really pushing me to release at the commercial level.

These were released in 2009. So it has been about 6 years. The Diode VCF went through three generations: black, green, black again, and now matt black. Each previous generation was 200 size runs, and hand made-dam those days, no more ever again. These days I do 500 runs for each product. This recent version is the first to be made on the pick and place machines.

My first module ever made and sold was an arp 4075 vcf with a clear plexiglass frac rack format cover. That was made in 2003. Since starting I believe about 35,000 pcb's have passed my hands. Either duds, prototypes, or winners."
