someone upped this on "another" forum...worth a look!!!!!

[pinkjimiphoton]

thanks rob...with a little luck, tomorrow i hope to get that footswitch fixed...as luck would have it, the diagram posted earlier in the thread here explains where the wires go to!

gonna wait til dino checks in, i think he's too busy playing with his now to talk ith us, lol...but i wanna check in with him as to make sure i get it right.

it's such a trip to have this thing come home...i mean, what are the odds? this was supposed to be lost in a mobile home/tractor trailer accident in arizona in 83...figures the guy i traded it to lied to me, and traded it off for weed...lol.

[deadastronaut]

haha must've been good weed!..

[pinkjimiphoton]

lmao...dude...i traded it off originally for a half ounce of columbian rainbow and a solid-state 50 watt vox bass amp combo with 2x12's...

if i know my friend, it was probably homegrown, lol...

Hi guys,

This weekend was the final push to empty my house, because I'm signing the papers Wednesday. Haven't had time to play with it  
Between that, work, and my son's baseball, I'm considering moving to a planet a little further out. One with a longer day!

Anyway, I've already taken some outside shots, but I'm going to crack open the sucker this week. Probably Wednesday night, to photograph the inards. Especially the trace side of the main board, and all the offboard wiring.

Hey Jimi, if you max out the fuzz, and run the fuzz rep on max too, do you get ticking? Mine ticks when I go past 5 or 6 on the slider.

Dino

[pinkjimiphoton]

mine doesn't work yet. the fuzz is out of the equation due to shit being unwired under the treadle. hoping to get to it today.

the ticking i think was normal for the fuzz repeat...it was a "feature"...but i'm thinking ALL the electrolytics need to be replaced, just to be safe...these things are like 40 something years old, and i bet if you're having an issue, that'll be it.

when i get back later, i'll post where the wires are coming from, and the colours, in hopes you can help me tell where they need to go...then, with luck, i can actually see if it's even working, or broken, or just a case of not being connected.

thanks bro

peace

You guys have no idea how jealous I am!  I can't wait to get a clone going...

[pinkjimiphoton]

no worries ry, we're gonna make it happen!!

[pinkjimiphoton]

ok, finally had a chance to look inside it and mess around. way back when i had the presence of mind (i cannot believe this to this day) to twist together the three wires that actually controlled the output of the effect...i had effect, bypass, and output twisted together, and just put them on a 3pdt switch. it now works, and has bypass!!

one of the wires coming out of the bypass led (if it even actually IS an led) is broken off. that sucks. but the rest are there.

hoping when dino gets a chance, he can shoot me a couple detailed pics of the footswitch wiring so i can get the lights on the left side of the foot board going.
i'm gonna play with it one way or the other to try and figure it out...it looks reasonably easy, but i wanna get it right.

the lights on the fuzz switch on the left are dead. i can live with that. i'm not getting a "tick" as dino describes. it's actually sounding alot like i remembered.
very, very sick.

i'm thinking about replacing the three remaining switches with modern ones tho, as they appear to be kind of intermittent. gonna try some pot cleaner first, and see if it's just grunge and oxydation from years of being stored in a damp garage. if i do replace them, screw it, i think i'll put 'em on ebay as original ludwig phase II footswitches, i have a feeling i'll be able to get enough for them to fund building the clone.

i'm gonna take a cue from RG's geofex site, and take it down to staples and try to color scan the board and layout when i get this thing working. gotta LOT of cleaning to do...switches, sliders etc.

the wah part is working great, the formant filter is frankly making me tumescent, and the fuzz is strong depending on setting...so far, all good. can't seem to get some of the effects i seem to remember out of it, but hey, i was about 17 when i traded it off. my memory is pretty fuzzy.

when i can get a chance soon, hopefully, i'll up a video demo of it so you guys can hear the thing and get a taste of what it sounds like. please don't hate me!! i wanna make  sure that this thing gets as restored as possible, and do all i can so anyone who wants one can build it. with luck, we should be able to get a working prototype now that we've got two examples. i don't wanna tear it up too bad to get pics, but believe i can probably get a good shot of both sides of the board if i disconnect the footswitches, balance pots and jacks. hopefully doing so won't end up killing it.

anyways...that's the deets. stay tuned...

[tcobretti]

Dude, if you get this all worked out, it'll be the first pedal I've built in a coupla years.

I can't wait.

[pinkjimiphoton]

getting closer...i need to identify this component:



here's some more pix

[R.G.]

Incandescent bulb, probably. "Grain of wheat". Almost certainly if that plastic rounded doodad stuck outside the shell where you could see it.

[digi2t]

Hey boys,

Prelim pics, including one of the trace side of the motherboard; May take some time to load, because I didn't downsize the pictures. I working on a short demo video, and I've started to trace all the off-board wiring. I soon as I have my DMM out of storage, I'll start taking some readings. Especially at the trimmers, and the marked test points on the diagram.



















I hope that they are clear enough. It's just a cheap Polacrap point and shoot. If anyone needs more pics, or tighter close-ups, just let me know.

Off to shoot the video now.

Cheers,
Dino

Dino,

Excellent pictorial of your project. I think you have done a FANTASTIC job of documenting for a reverse engineer.

Any pictures of the component side of the "smaller" board? I see you posted trace side pics.

[pinkjimiphoton]

awesome dino!!! thanks, i can see clearly how to hook up the disconnected wires. the colour codes on some are different from mine tho, i think...but only on those "grain of wheat" lamps. nice!! speaking of which, the bottom plate of mine is missing, so i forget where the serial number tag was, but it fell out of the inside of the box... the tag says

model no 9000
serial number 1642

supply voltage 120/240 volts

50/60 cycles 15 watts

[digi2t]

Hey Lacky,

I didn't concentrate too much on the component sides, since they are laid out along side the schematics on the cover panels. It's pretty much WYSIWYG. I figured it was more important to provide detailed pics of the trace sides (especially the motherboard), so someone could easily verify a clone board. I should mention that there are jumper wires on the component side, but again, clearly marked on the layout drawings.

I have started to play with the trimmers, and basically they tend to define min/max frequencies for various functions i.e. wah frequencies, voice frequencies, rate hi/lo limits, etc. Honestly, I don't believe that there will be any "hard and fast" setup rules insofar as dialing this puppy in is concerned, but I'll try and document what my ears are telling me when I play with them. I don't have any DMM readings, since I've just moved, and most of my sh*t is in boxes or storage. I just marked their positions, and went from there.

Bit of a scare, I was setting up to shoot my video, and I realized that I had lost the fuzz. YIKES!!! Found that a wire had broken off at the solder on the fuzz/voice switch during my explorations. Video will have to wait until I get that repaired. DOAH!!! I have to  be gentle with this baby.

Jimi, mine is serial #1277, all the other info is the same. Could it be that they started the serial numbers at 1000? I mean, 1600+ units couldn't just disappear THAT quickly. Maybe it's a case for a giant meteor 
I don't believe that the wire color/polarity for the lamps will matter, since they are incandescent.

Gotcha!  I still want to say that you did a GREAT job with the pics. Very well done!

I am sure you are aware but.... these are not MULTITURN trimmers are they? If so, then marking the positions may be moot. Just a thought 

[digi2t]

HAHAHAHA....nooo, not multi turn for sure. Big-ass dial trimmers. But, I did want to retain the setup as I got it, until I could really record readings on a DMM, and benchmark everything. I marked everything for my own piece of mind, K.I.S.S., keep it stock stupid 

I should point out, the fourth to last, and last pictures go together. That's the control board. Somehow the pics got mixed up. Anyway, i don't mind shooting more, if anyone needs it. I'll keep it apart for now, not only for measurements, but to answer any and all questions.

Well, off to repair the wire, and shoot some video. Jimi, I'll take it into the "ticking zone" at some point, then you'll see what i mean. DAMN IT!!! Why can't you be next door? FUDGE!

[pinkjimiphoton]

ROAD TRIP!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[pinkjimiphoton]

just took a voltage reading from the wires going to the lights to ground...reading about 18 volts. so....will i blow out these lamps (5v) if i wire them up? should i try adding a resistor in series or to ground to drop the voltage? the main concern is that all 4 lights on the floor part of the board are wired in series, pretty much daisy chained...the lamps i got are a fraction bigger than the original, but i'm concerned about the voltage thing. i have a feeling they'll be ok, i may be reading it wrong...it's actually 17 volts ac...dumb newbe question, but because they're ac, do you think that means they'll be able to take the higher voltage? nothing else is gonna actually fit out of the ones i looked at...await your advice guys, worst case, i gotta buy some more. the important thing is, the unit is actually working!!!

dino, can you tell what the resistance of the fuzz repeat pot is? i need to replace the slider, it's broken...still useable tho, but i hope to get it in the ball park.

the "mushrooms" on the foot switches mount with an allen screw, and i remember seeing similar buttons somewhere...mouser? allied? the key is, i belive they're available, and should mount right on the button of a standard footswitch.

thanks peeps...

[boogietone]

I pretty much read this thread in one go. It is like a real life version of Pawn Stars or some such. 

In any case, I am in for making a build of one of these. What can I do to help?
