I am building a kit for a friend who bought the SMT boards of the STEVE’S MS-22 DUAL VCF MODULE from Three Tom Modular and then realised SMT is not as easy as through hole soldering.
The MS-22 is a dual voltage controlled filter, inspired by the classic Korg MS-20 filter, with an innovative modulation matrix and one of the highest function-to-hp ratios in the land of Eurorack.
So time to start with Board A

First board almost done.

Looks like a very nice piece of kit Icky. 

Re: STEVE’S MS-22 DUAL VCF MODULE
Finally received the last components for the 1st module which is now complete. Now for the next 3 modules.
Re: STEVE’S MS-22 DUAL VCF MODULE
Finally got some time to do some SMD work on this, the third board. I have forgotten how time consuming and annoying SMD work is even with all the right equipment. It’s almost been a year since I touched it last.
One more board to go but I dont think I can muster the enthusiasm to do it today.

Yeah, SMD stuff is a huge pain, even if you're able to do it and have good equipment. Looking good, fingers crossed you can muster a bit of enthusiasm for that last board 

Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Thanks, I may give the final board a go today. Its going to be interesting as I will have to test the module works so will have to learn a bit of modular VCFrubber_jonnie wrote: ↑Tue Dec 26, 2023 3:25 pm Yeah, SMD stuff is a huge pain, even if you're able to do it and have good equipment.

Good luck, I'm sure it'll work first time with your skillsIcky wrote: ↑Wed Dec 27, 2023 10:34 amThanks, I may give the final board a go today.
