Sounds great!

Damn, you and Delepathy are blessed people!
So what kinds of tubes does this rock? Is that a 5696 for a thyratron?
Also noticed it sounds less noisy than the R55, especially at lower frequencies— speaking of which, this sounds like it can go much lower than the R55! What kind of range does it get via CV?
Starting to get pretty excited for this.

Delighted to see it even includes the VCA input in RK size. Nice work, Eric! Envious, Ritchie.

Thanks. It uses a 5696 thyratron and a 5702 subminiature pentode, because that's all I could fit into an 8hp panel. It uses about 200 ma from +12 and a few ma from -12, no +5.

Guess I should get panels made, eh?

Due to the amount of "cold inrush" current coming in from the Sodomizer panel, I had to find a PSU sufficient enough to even power it. Which, in the Serge world, doesn't seem to go above 1.7A (which'll power up to ~5 17" panels) for commercial PSUs. 1.7A would've been just enough to ONLY power the Sodomizer lol. Thankfully, Logan Erickson (MA) builds his own "Ammo Box" PSUs, which carry a hefty 3.4A. I asked if he could possibly build a custom supply for me, that reaches at least 4A, but he didn't have the time. So I bought an Ammo Box. With that, it should be here within the next two weeks, along with a CGS74 distro board. By then I'll be posting some demos of my own. I'll forever be jealous of ritchiedrums though (;

I would have expected a 1.7A supply to run that load, but then I have NO idea what kind of power supplies STS had used or is using. No one seems able to tell me. I suspect it's a low cost computer brick. That's what Random Source is using in the PS-M and the powered boat. Dunno.

There's nothing on EGRES about power supplies. It's also badly outdated and full of broken links.

In my world 3.4 amps isn't very hefty, but then there are absurd numbers of tubes in my Euro systems. If you wish I could build a better supply for your Serge panels. Just pay for the parts. It would be far cheaper than anything STS or RS is offering.

For chrissakes....this thing costs $32 and puts out 16.8 amps.

These panels look different to the ones on your website. Is this how they will look? I've been gear-lusted into contemplating a row of Metasonix. I shoud add for the sound. I love the sound.

Ritchie's panel is a prototype model, and Delepathy's is a custom 4U Serge panel.

Your power supply on the other hand will try to murder you in your sleep.

THIS! Do it!
In a world full of cloned vintage circuits and increasingly convincing softsynths, Metasonix is a sound that you still can't get anywhere else.

Ha! OK thinking about it.

@gringostar I have plenty of power available.

Logan sent me a photo of the distro. board and Molex-to-XLR cable yesterday (below). Surprised me with the cable being entirely yellow. A nod to Metasonix, of course.

RKP rules! just add a black banana jack to avoid ground loops with your serge

I have other plans in mind. I appreciate your suggestion though!

I was a little sad about not being able to get a s2000, but a couple of thyratron VCOs and an RK2 instead would be lovely.

Eric, any update on when the RK7 will be out? Is is what's next, or is your new standalone synth next?

In a couple weeks--panels are being screenprinted

Post by **lisa** » Fri Jan 24, 2020 6:11 pm

Cool! I’ll have to start looking into Hz/V to V/oct modules then.

It’s the only reason I keep the SQ1 around.
