The LED didn't shine overly bright that first time, did it?
Don't laugh - that's what happened to me once. Soldered a LED in the wrong way, and it lit up brightly in reverse, but only for a short time ...

I thought I might have blown the LED when it wouldn't light again so I tested it on it's own and it still works...

Yes, my 6 year old kid was "helping" me on another project and connected an LED to a 9v battery and it lit up like a torch and exploded! Luckily no one was hurt, that's why I had asked about the LED a few posts back.
So if my LED is working.
And the Relay is working (at least it sounds like it is).
And the components for the Switch connector look ok (right?).
Could it be the actual bypass switch I'm using? Temporarily I've just been using a simple on/off toggle switch.

Hmm - let me use this to make a general remark about debugging.
I'm really trying to help that all of you are getting these projects to work, but there's only so much I can do. Sure, it's my circuit, and sometimes I may have some ideas what can be wrong, even from the other end of the world. But normally it's much easier to find an error when you're sitting right in front of the board.
You have a relay that gets current.
You have a LED that is functional.
If you look at the schematics
http://www.jhaible.heim.at/compact_clone/jh_krautrock_phaser_sch.pdf
the relay and the LED are simply connected in parallel, each with a series resistor of its own, but controlled from the same transistor.
It can't be so hard to trace the error in such a simple configuration when you're sitting right in front of it!
OTOH, it's extremely hard to trace such an error from the other side of the world, because it certainly isn't a logical problem, with a simple parallel connection of two paths - it's most probably a bad solder joint, bad component, something like that.
If everything else fails, remove Q5 entirely, and connect a switch (and/or a jack for a remote switch) directly where the C and E of the transistor would have been.
In that case, you don't need a swich with momentary action, but an ordinary on/off switch (or latching footswitch).
Which still leaves the problem with the LED, but I'm sure you can solve that!
JH.

I understand Jurgen, I have a pretty limited grasp on electronics and I know I'm asking a lot of you to guide me through building this phaser.
Please know that the last thing I want is to annoy you with questions you can't answer or keep you from offering your PCB's in the future. If you don't have an answer or don't care to answer, just ignore my ignorance. Like you said, I'm the one "sitting in front of the board", I'll figure it out eventually!

That could very well be a problem. I had an on/off switch in there at first, as I somehow thought I needed one. That doesn't work. The circuit needs the short pulse from a momentary switch, it won't switch otherwise.

Good point - but that still leaves the relay getting current, and the LED not.
Which is something I don't understand, as both are getting their current from the same transistor.
Clay -
if the LED once worked, and now doesn't, but still is functional by itself, it's most certainly an intermittent contact somewhere.

I had a feeling the switch might be an issue. Thanks for the info Etaoin.

I'll try replacing the switch with an actual momentary bypass and take another look at the LED.

About the switch: If everything works as intended, you can toggle the relay and the LED by momentarily shorting the two contacts of te SWITCH board connector with the blade of a screwdriver ... easy to check ... just make contact for 1/10 sec or so.

I got it!!
I had blown the LED I was testing with at some point and didn't realize it, so I'm not exactly sure what was wrong as I could have fixed the problem awhile back and wouldn't even have known. It definitely didn't help that the switch I was using has to be pressed twice to turn on and twice to turn off...
Thanks for all the support, now I can work on getting the phaser out of a tupperware bin and into an enclosure!

Bypass via foot switch? |

Below is a quote from a review of the original Compact A Phaser via Harmony-Central.
| Quote: | | it actually finishes it's phase when you bypass it with the footswitch, a cool deep fade out. It's sound is sweet, deep, organic. It's so full of character. |
I haven't hooked up the foot pedal yet, can anyone confirm this is the case on the clone? Jurgen?

In my version, there's a hard bypass. Switching the relay will certainly not fade out anything. The original didn't have any means of bypass at all. As far as I can tell, a switch could be used to turn the modulation off, and the LDRs take care of this to be a fade, not a switching.
I'm pretty sure this will work with my version as well, by connecting something to the "AMOUNT" connector.
But I'm also sure that if you're doing this, you won't get a completely unprocessed dry sound (neither in the original, nor in my version).
It may be worth a try. Then you'd have a choice of two bypass methods.
JH.

USA Krautrock PCB Builders - Lamp Sockets |
|
|
I have a few to spare. PM me if you want me to set aside some for you. I'm waiting on 7V 100mA lamps to go with them - let me know if you need those too. Again, I only have a few, but am willing to send to anyone in the US. I'll consider Canada and Mexico too. 
Not sure of the price yet, but they will be as cheap as I bought them + postage. SOmething like a buck per socket and 1.25 per lamp. |

Your hard bypass is what I'll be using most of the time but I might give this a try just for fun.

Hi Jurgen,
I'm happy to tell you that I finished to solder the Compact Clone board and works perfectly. Here is a picture:
For LDRs I used successfully the ones from Banzaieffects and the 7V 0,1A lamps from calpedel (http://electro-music.com/forum/post-170500.html#170500)
The mentioned LDRs have an extended range (I measured around 30 ohm to several Mohms varying from light to dark) and look very similar to the official ones suggested for this project.
BTW.. while mounting the components I found a funny similarity between the compact clone and Stonehenge

If anybody in Europe is in need of the relay. It seems i accidently ordered two relays instead of one from digikey.
just drop me a PM if interested.

I PM'd you. Would be interested in socket + lamb + any other hard to source parts(for this project) that you have extras of. |

I decided to use an MOTM style power supply to power my racks. So im wondering if the following parts need to be installed on the pcb or not?
The two 10uf tantalum caps, 22uf electro, 100uf electro, the 5 watt resistor, and the three bd239c.
I have already omitted a few of the other parts from the board. Im guessing I do need the 5 watt resistor, and the three bd239c, but I just want to double check. Are these supplying power to the lamps?

Just looking at getting most of the parts for this project, and I was pondering a few things:
1) The "manual" switch is a DPST isn't it?
2) I'm looking for a suitable switch for the "switch" control, which is a momentary. I was wondering if anyone might have found a nice looking on-off momentary from Mouser that doesn't cost the earth?
3) Has anybody had any luck running this project with 6.3v lamps? 6.3v lamps are reasonably common in Australia.
Cheers!

I thought these things are very common in guitar pedals!
If you rather want to use an ordinary (not momentary) switch, you can just throw out the electronic latching (4007 and surrounding components), plus the transistor that drives the relay, and connect your switch where the transistor has been.

Here's an example for the switch I had in mind when I designed the Krautrock Phaser:
http://www.musikding.de/product_info.php/info/p803_Momentary-1PDT.html
I'm pretty sure similar ones are available everywhere in the world.
