After quite some lurking here I thought I'd start out with a contribution as my first post. :-)
I got a Mad Professor Tiny Orange Phaser from eBay for quite a good price, and it seems there's a demand for gutshots. Here's the first couple of shots (sorry if the quality is not up to standards - I'm using the camera in my mobile phone):

The board is glue-wrapped in this black foam, and the glue is quite sticky, I'm afraid I can't get it all off.
Chipped away at this thing for about an hour with the pick that came with a Rat Shack iron I bought a couple years ago and got most of the goop off. Two resistors were wrapped in heatshrink under the goop and all of the film capacitors have the markings sanded off. The ceramic cap is painted black. I've got an LCR meter coming in the next week to measure them all. Looks like there are components under the jacks too so I'll have to remove those as well. Will get...
I do not Know for sure, but the COT50 on his site looks like a Super Hard On under a different name - clue: bias control - wonder if it crackles too :lol: :lol: :lol: :roll:
I don't know for sure, but I've heard it was just a mxr dist plus clone
I hope this post is in the right forum.... if not, mods, please move. :D
I thought some people might be interested in the infinitphase schematics. See attached. No secret mojo or hard-to-find parts here ... the essence of it is this:
- CV section consisting of a tri/sqr LFO, controlling a LM3914 LED driver; both of these CV sources can be used to modulate the LEDs which drive the...
- phase section, which is simply a Mutron Biphase channel extended to 8 stages + a couple of tweaks...
I got this last week and had to trace it. Great through zero flanger and is signed inside by Justin, thanks for a good build man. :applause: I was hoping for an easter egg in the form of a hidden effect in the Eeprom but no such luck.
hello there, probably not much interest but i thought i'd post/contribute it anyway! here's my little crappy handdrawn schemo and the (reversed) handrawn trace with parts values on there if someone wants to make one. notice the vol/imp. pot at the frontend of the circuit---i guess keep strong bass signal from overloading it on the frontend. it's very simple so some here might try it on perf or vero----i've build one already for a guy and it works fine from my pnp blue reduction of this. some...
I knew this was a bad idea. :twisted: :secret: :whappen: :horsey: :slap: :blackeye: :hug:
:block: and another one down.
Do I get 3 lives here? I've got more mods but I'll let you be the judge. I know this one ain't it- and that other forum ain't worth it. Sorry I tried, yoda.
I'm tired of building the dam blocks.
TGP, it was too easy to get kicked out. I hung out too long in there.
That said, there are probably errors everywhere but they are not intended to hurt anyone. I kinda winged...
Here's another beautiful D.Main work - Gravity Isolator . Fleshhead son.
It's MKII circuit with fixed fuzz and tone section on the output similar to MKIII.
Electro input and fuzz caps are not confirmed, I just followed values used in Fleshhead.
Same thing for output caps - yellow one is smaller than 100nF so it propably has smaller value - that's why 47nF. 4,7nF fits nicely to it :)
Transistors are Mullard OC82DM.
Lot's on underboard jumpers shown on layout as white wires.
This shit is embarrassing. I can't believe these guys are still in business. I really, really hope this is some kind of joke and that I just fell for it.
I snagged these off TGP in the for-sale section. I'm no law-monger, but I'm pretty sure this little educational post falls under fair use in US Copyright Law.
From the name and the controls makes me wonder if it's a subset of the Meatball? Missing the high pass filter and some slight functionality in the other switches. Sounds killer and at $269? Price seems VERY right.
Here's layout for D*A*M - FZ-781 which is Tone Bender MKII circuit with some mods (input filter and switchable output caps).
I'm not sure values of the caps - I can't read values from this gut shot, but those ones should done job fine.
Transistors are Mullard OC82DM. Schematic added to layout.
I have no pics of the unit right now but here's the schematic of unit #2 that I bought on ebay recently. The construction left a bit to be desired: reverb tank not secured, pcb not secured, tube socket mounted with screws only (no bolts/nuts). The LM386 was bad so I replaced it. The power jack doesn't have polarity indication so that probably destroyed the chip. The Dwell control causes a lot of hum at either end of its rotation.
