Here you go, guy. This oughta put some twinkle in your eye: http://img.photobucket.com/albums/v474/mhammer/PH-2_2.png
And for comparison purposes, here is the table-top RPH-10, a close cousin: http://img.photobucket.com/albums/v474/mhammer/rph10-a.gifhttp://img.photobucket.com/albums/v474/mhammer/rph10-b.gif
Note a few things about the PH-2:
1) It is OTA-based, like the Small Stone, later Ross, DOD FX20, Moog Stage Phaser, and Moogerfooger. This provides the potential for superior stage matching, but it also puts the circuit at risk for distortion since OTAs don't handle large signals well all the time. The IR3109 was essentially Roland's take on the old SSM2040, also a dedicated quad-OTA.
2) To cope with the possibility of distortion, and especially with cumulative noise from so many stages run at such low amplitudes, the PH-2 uses an NE571 compander chip. Not that many phasers use them. This is one that does. It can be replaced with an NE/SA570 for a slight bump up in noise specs.
3) Like the MXR Phase 100 and some other commercial phasers with more than 4 stages, not all the phase shift stages are swept. The two IC6 dual op-amps (one of which has the wrong number in the schematic and is presumably IC3) are each fixed (i.e., unswept) allpass/phase-shift stages. As in the Phase 100, these add to the cumulative phase shift and result in more notches even though they aren't swept. When you switch from 6 to 12 stages, you're getting 4+2 (swept/unswept) and 8+4 (swept/unswept).
4) Because of the switching requirements for going between 6 and 12 stages, a CD4053 CMOS switch chip is used. Though you should obviously be careful about the IR3109, given how irreplaceable they are, maybe be a little more attentive to the CD4053 since it is the more static sensitive chip on board.
i should clarify that when i said i dont feel like getting scammed what i meant was - i dont feel like transfering money to a paypal account and never seing the schem
i have heard rumors on various forums that places like schematic connection are dodgy - you pay via paypal and then you never hear from the guy..
i searched the net for a while and couldnt find it anyware - so i have to ask - does anyone really have one or has this guy just made a list of all schems that are not available and said you can buy it for 5 bucks - just pay now..
re postage - a pdf of jpg is fine - i dont need a printed copy - and in this day and age i don't really see the need to physically post something - so it just adds to the "dodgyness" factor.
Again, nobody makes a living out of providing schematics, no matter how much they charge for it. If you've ever been to Mark Glinsky's site (http://www.markglinsky.com/ManualManor.html
) or Candisc/Ranger (http://www.candisc.com/ranger/
), you'll be tempted to mutter to yourself "Who in their right minds would want
this stuff?" as you scroll along. And you'd be more or less right. Much of the accumulated paper will sit unused for very long periods of time. Do any of these folks have the time to scan everything? No. Do they have the time or support to get all of it organized so that it is available at their fingertips? No. Do they have enough time on their hands to be able to make note of or respond to every e-mail promptly? No. Basically, you're dealing with one-man operations that are well-intentioned, and honest, but maybe not well-organized enough 100% of the time that every request that comes in instantly turns into someone swinging their swivel chair around, sliding down the row of filing cabinets, and pulling out the drawer that says "Rheem to Roland", and slipping one of the many copies in the file folder into a pre-stamped envelope.
I don't want to keep harping on it, but Steve Daniels is as honest as the day is long...probably moreso. Before he was able to launch Small Bear as his primary source of income, with someone else to help him fill orders, he was doing it on top of his day job, on his own, out of his apartment, with the scowl, eye roll, and occasional hug from his lovely wife Judy. It was VERY draining on him, but he managed to get past the hump where the degree of organization and speedy response people thought
they were going to get when they looked at the website was finally able to become something of a reality. And even though he is much better organized these days and has hired help, all it takes is a flu bug to really screw things up for a while.
And there is the nub of it. It takes almost nothing to type up a list of documents you have lying around somewhere and post them in the barest of html coding over top of a background graphic with a contact number/address. It takes one whole helluva lot more to be as sustainably organized as any of those big distributors with dedicated phone staff and accountants, and my sense is that a lot of the "manual gatherers" out there have a wee bit of the Simpsons "comic book store guy" in them ("Worst mono synth...ever
"), trying to turn their love of technology into something sort of like a business. One needs to scale back expectations when dealing with them, because they WILL fall behind in responding, will print requests out and lose it under a pile of paper somewhere, and will fall WAY behind if they catch a cold and Bob the imaginary invisible 24hr assistant decides to go surfing that week. It happens and is as fundamental a part of doing business via the web as finding out that the 23 year blonde you thought you've been corresponding with is really is really more like Mrs. Hufnagel from St. Elsewhere.
We had a guy here in Ottawa, who had a "store" (i.e., semi-condemned rickety old house with a sign in the front) with an amazing collection of obscure gear. Just about all of it was inaccessible, tucked away behind stuff, generally covered in dust, and not priced appropriately or competitively or even visibly. The guy himself, while pleasant enough, was a bit of a nutbar who didn't really seem to know a lot about what he had (hence the weird pricing) except that it was obscure. He could have actually made money but was not a businessman and appeared to simply love being around gear. Naturally, he went belly up, though we don't seem to know where all the gear went to after he closed. Again, honest as the day is long, but shopping there was draining because
it was so disorganized. However, at least you knew it when you walked in. I'm not trying to cast aspersions on any of the folks peddling schems, but one should keep in mind that many of these folks can be of similar ilk: great folks, honest and happy to do favours for you, but not in a position to always follow through as efficiently as you'd like. In this day and age, that's simply one of the things we have to expect and accept.
Hoep you can get the pedal up and running. That puppy is just about as packed as the DC-2 is.
