Yo! This project started couple months ago, i never knew these existed until i saw Juan and Cleggy pulling some of these out and found them to be amazing and a MUST to build... almost entering them in the Rites of Passage kind of built... for me that is.
So i got a board etched by Haderbasher, then took full of notes after chatting with Juan and refering to all the information on his Stompage... ...then came time about the enclosure, the type of effect this is, with no knobs just switches.... ...i thought that my finishing techniques would'nt be up to the Epicness of this built so i decided to go for the full monty!
I gave white card to John to design me an enclosure with the killer Envirotex technique that Cleggy got, deceived i was not... ...fucking amazed i surely was! ;D
Then time came to populate this board, something i had done for the most part many weeks ago....
Just the traces on this layout are worth the built... ...forgot to take a shot of the actual pcb when i got it.. but here's the transfer, things where so artsy back then...

Ok.... to get this thing to properly works, there's some slight modification to perform on the circuit (value and part change) but you also need a +12V/-12V Bipolar PSU and an input buffer, using a klon buffer.

Matched 6 pack JFET came from Stomptown in a nice little semi-conductor trade we had going, thanks Jon! :)
The enlcosure came all prepp'd, Josh's OptoBypass, jacks and speed switch where all hooked when i got it... when you put your nose in the work of John... you fast realise that craftmanship can be brought at a totally other level.
So i did my best to stuff this box to be up to the game, wich i think i nailed.

It fired up first time, got the Bias, Balance and Feedback setup and sounded GREAT!!! though i have a little issue with my switching, inverted some wires, going to fix that... and then..... post the exterior ;)
Rej!
That PCB layout is a work of art as is the gutshot! Can't wait to see the outside and I'm glad you put those jfets to good use! But the question is: What is it??????????????????????????????????

That's bad ass!
Beautiful! I remember this one now. Me wants one!!!
Question: where do you get this trimmers and how is the quality? Also, are the pins spaces like the Bourne type? They look sweet!
Thanks :) Found my small issue in the switching setup, had a MPF102 in opposite direction.... thing is just so lush and the ramping is a thing of beauty!

I buy those on ebay from a seller called EricCheung iirc, the quality is very good overall, i have some of those in pedals that i have played with the bias more than 50 times and they stay precise and have a firm feel to them, there's also a center detent when in the middle.. and from those i've tested prior to give them the ok, the notch is accurate too.
You have to work lugs 3 and 1 to make them fit in the Bourns pot spacing found on most DIY layouts, they have the spacing of the bigger ones, can't recall the model number from top of my head.
First time i saw those was in my BBD big box Maxon... really digged the look. :)

Rej, I would love more info on this some day. Your board came out great and the artwork is awesome also.

Other than populating the boards and dropping them in the enclosure, i have'nt done much.... hehe
I'll come up with something to put in the Archive section of our support forum, there's couple projects that there's a common love for, among the grind crew that could get referenced in there....
Amazing!!!!!
The box looks fantastic, sooooo beautiful
Damn that looks good! :o
Whoa. Rej did a decal! :D
I love the look of the old handdrawn PCB traces. You could even put it on the outside of a case and people wouldn't guess it was the circuitboard at first.
Knobs? Knobs?! We don't need no stinking KNOBS!!! That looks incredible through and through. The PS-1 is the standard by which all phasers continue to be judged. Even the Mu-tron Bi-phase is said to have been designed around the sound of the PS-1.
Great work!

So this was a group build, in effect? :)
I don't recall the details of the PSU for this one, does it run off 12VAC at the socket?
That's a very nice pedal! Kudos to the team. ;D
love it!
it makes me feel almost like i need a stompbox with no knobs.

A decal? Whaaaaaaat is this madness?
Yeah, the hand drawn PCB traces are fun on that one. The ground planes look like tribal tattoos as well.
Great build, Rej. Love the knoblessness.
Thanks guys! The only way i'll ever have decals on my DIY builds is if someone does it for me! ;D

Definitly should and for once it ain't a switch, TB looper or whatever... it actually makes a sound! :o

At first it was'nt a group built but once you start thinking of who took part of it... it is! One of the nicest thing of this hobby... through small parts and envellopes in mail you end with something beautiful to play around with :)
The PSU is based around a DC/DC Converter brick, +12V/-12V for this one, getting it's supply from your regular 9V.

Great work!
I could really beleive that, this thing sounds awesome, the filtering of each and how it cycles through it's stages is something i had'nt heard before... the slow speed is the nicest i've ever heard, once you start fettling with the footswitches while playing, the ramping gets you in the leslie range... but with a Phaser voice... much awesomeness!
Epic, Rej .... Epic. That's one of the special ones.
Actually, I just did my first decal - and I like it. Prolly gonna do more that way.
Killer! Well done, Rej.
man that came out great, and no knobs is so 2015!! The PCB traces are really cool, you could make a great looking decal just from that (the one you have looks excellent BTW). Cigars everyone!
Fantastic build Rej! I think I would have guessed who did that enclosure if you hadn't said. What a team!

Did someone mention ramping?! This thing ramps between speeds? Is it possible?! Why haven't I build it yet?! How can I get the board and the build doc? Would any of you fine gentlemen help me out to get started?
Just listened some clips on youtube, I am amazed. I remember juan's builds like I've seen em yesterday but I haven't dabbled much into the build nor the sounds. My god, it sounds great, and the ramping is something I LOVE.
Is there a schematic for this?
Thanks guys! :D

Ramping, Lush, Lush ramping it is! 8)

Yep, shoot me your email in a PM, i'll forward you the info we've got.
Also, since i build it and way before i did... by listening to Juan's clip, clips of the original on youtube... ...we've been discussing in a random way (Juan and I) of how to make this thing really DIY friendly... ...that work is now transfered between Jason (Jubal81) and I for the completion of this... couple mods and improvements will be part of the overall design... but the main goal is to preserve the authenticity of this particular sound.
Stay tuned!

That's just beautiful, inside and out. I remember the original but had forgotten that it ramped. I had this major flashback to working at Gordie Brandt's Music in Saskatoon and we had one of those and a Mutron III. In 1975-ish I remember thinking "who would want this old crap when you can get a Phase 90 or a Small Stone?" Keep us posted on this one. This might drive me back to etching a board just to get those cool curves.
Ok, so this is hjappening as a members projects and tutorials thread? I just have to be patient??

The other day i almost bought an original unit from Reverb... was coming with the original optional footcontroller aswell, the price was'nt too bad but i just could'nt at the moment.... It's definitly the ramping and overall Leslie vibe that this thing got that makes it so charming. Lucky you that you've used a real one back in the days! :)
