TTSH V4

We are pleased to announce the availability of TTSH v4!
In collaboration with Human Comparator, we have taken the TTSH v3, modified and updated it, and are making it available again Spring/Summer 2019!

TTSH V4 product page: https://synthcube.com/cart/ttsh-v4

TTSH v4 includes the following updates from V3:

1. Corrected the Pin out for the 2N3954/8

2. Corrected the missing trace on the filtercard 4072

3. Corrected the bc558 wring pinout on 4012 VCF Card

4. Corrected the ‘via’ filling that created issues with jacks

5. Add mainboard VCF header missing -15V power

6. Add mounting hole for Gatebooster PCB standoff

7. Removed dimming autostart on LED

Is this something that you guys will regularly keep,in stock?

synthcube · Post by **synthcube** » Mon Jun 03, 2019 12:35 pm

It is, yes.

I'm on the fence. I've built i think 5 or 6 module kits and never had an issue, but the sheer scale of this build makes me wary.

If it is like earlier versions (I built a v2), it is very do-able with that level of experience. Each "module" had its own jumpers for power so you could power & test each one individually. Just take your time with aligning and soldering the jacks.

That’s why I asked my question... thinking this might be a 2020 purchase

Only the V1 has power wiring like this. V2&3 (and presumably 4) how power integrated into a 4-layer PCB. There is a way to disconnect power to specific modules on these subsequent revisions, but it requires trace-cutting and is more of a last-resort thing.

That said, it’s still not *that* difficult of a build. Most of the common mistakes have been well-documented at this point, and if you can take things slow and carefully, it’s well within the ability of most builders who have at least a little building/troubleshooting practice. Certainly not a beginner’s project, but also not something that should scare off all but the most experienced.

Interesting, I always thought I was a late adopter!

I never used those jumpers myself as they seemed a bit superfluous, but didn't mind them.

next up us the next run of 1601 sequencer pcbs, panels kits and cases

Pseudo · Post by **Pseudo** » Tue Jun 04, 2019 4:39 am

For those of us who have previous versions of the TTSH will there be the option to purchase the case separately?

My woodworking skills are not the best and I do regret not purchasing the original metal case when available from THC.

synthcube · Post by **synthcube** » Tue Jun 04, 2019 6:56 am

Yes we will be happy to add that option... thanks

Its a big project, with a big reward. Between versions 1-3, V2 was the easiest build, because V3 was full of board level bugs that required tracking and fixing. With those bugs worked out of V4, it should be as easy as V2. The V3 design is superior to V2, especially with the DC-DC converters moved off the main board. It is possible to build the PSU to be very quiet.

There are a lot of people here who have built multiple TTSHs. I have built twelve. So you won't be alone with it.

Great news, @synthcube!

Will there be an option for a covered travel case with the pre-built option, or only a studio case?

Thanks!

jonny_w · Post by **jonny_w** » Tue Jun 04, 2019 10:07 am

Awesome news! How long will the pre-order be open for?

Jaytee · Post by **Jaytee** » Tue Jun 04, 2019 12:10 pm

Don’t mean to add a bunch of noise to this thread, but damn.... I’m excited for this. Don’t know when I’ll be able to afford to start this project but it just warms my heart to have the option available again.

ultravox · Post by **ultravox** » Tue Jun 04, 2019 5:20 pm

I'm happy to see the TTSH will still be available for people wanting the ARP 2600 sound.

I wish much success to this project!

LektroiD · Post by **LektroiD** » Tue Jun 04, 2019 5:36 pm

Count me in for a PCB/Panel set. However, I can't afford the deposit just now, will there be extras made, or is this only for those who pre-order?

Pretty sure he's planning on stocking these

yes to clarify-- the pre-order should be open through about end of June. We will make and stock extra units, so if you don't want to jump in the pre-order, it will be a stocked item going forward. And of course we will have a demo unit or two set up here in the physical shop if you want to come play with one before you buy ....

Just pre-ordered a PCB and panel set. Can't wait to get started

Will you be fixing the power amplifier issue so that it is designed to drive 8 ohm speakers instead of the original 32 ohm?

Take care,
Doug

Jaytee · Post by **Jaytee** » Wed Jun 05, 2019 9:52 pm

If it’s still using the 2600 power amps, here is an alternate speaker that fits the footprint perfectly and provides a good load for the amps. https://www.jameco.com/z/FEB30045-Arndt ... 36674.html

Cheap and lo-fi, but you don’t use built-in speakers for pristine signal reproduction. You use them for quickly auditioning patches and sometimes mic’ed up for character. Either way the cheap ones are good.
