Hey guys

So I have finally got to the krautrock phaser in my back log.

Seems like a lot to watch out for but with this thread and the LED man site I am ready

I intend to but it in a Hammond 1550G enclosure with a Yamaha PA20 as I don’t want to deal with mains power.

One question, does anyone have a part number for the rotary pot for the stages?

Cheers as always.

I used a dpdt toggle wired like this for the stages if that's any help?

Me too. Get a dpdt on-on-on toggle off you go this route.
I used this one: 100DP6T1B1M1QEH

If you really wanted to go rotary, you only need 1 pole and 3 positions, so the switches in the jasper bom will work, since they have the ring that you can move to change the number of positions.

Cheers for the info guys.

I will go toggle switch. Takes up less space in my enclosure and easier to wire!

Thanks as always.

Hi All,

finally got this boxed today. Normally I hate boxing effects but I decided to go big (1550G) and it paid off, no hitches and plenty of room to work ;]

This is such a great sounding thing, respect to JH! RIP

Manymachines, That looks awesome!

Agreed. This phaser sounds sooo good. Since I finished the basic build it’s been hard for me to finish putting it in its enclosure. Every time I sit down to work on it I end up noodling with it instead of crimping cables.

thanks!

i know what you mean, I noticed after I posted this that the status LED has stopped working, I guess I mangled it a bit while boxing but I'm having so much fun with this I can't be bothered to open it up and fix it right now ;]

Hey Many machines,

where did you get the bulb cover /Cap thing?

And those knobs.

Very nice.

I will also be putting mine in a 1550G.

Cheers as always.

Hi just saw this message so sorry for late reply!

I got the lamp holder from ebay— https://www.ebay.co.uk/itm/MES-E10-Pane ... SwJe9eWkHq

I don't know if he's got any with the red cover left. The bulb JH specifies is just a tad too long for this holder so the panel nut inside the enclosure doesn't quite reach the thread. I think I botched it with some tape!

The knobs are from uk-electronic.de

look forward to seeing your finished project, so many variations of sound possible with this thing!

There's a lovely free plugin version here, I was surprised how good it sounds. Hard to find good flanger and phaser plugins that sound like the real thing.

Thanks manymachines. I was able to get the red bulb cover and it looks sweet.

Guys, are there any calibration guides

What do the 3 trim pots do?

Is it just trim to taste or what.

This is the longest it’s ever taken me to build a “pedal effect”!

Cheers as always

Can anybody who's built this on internal power recommend a transformer, preferably from Mouser or Reichelt? Thanks

I used this one: TALEMA 55102-P1S2 for both the Krautrock and the Tau Pipe phaser. It fits the vandaal Krautrock phaser enclosure if you are building that. It's only avaible from TME AFAIK

Thank you. I have been advised that Newark/Farnell MCFM70/18 fits that enclosure also, so it appears there are some options.

Well, this is a long time coming. When I first posted to this thread it was June of 2015. This was one of the more difficult builds I'd done and I
kept running into problems. Then I'd put it on the shelf. Get it back off the shelf. Tinker a bit. Put it back on the shelf. But it wasn't until today that I almost pulled the trigger on buying an original Schulte Compact "A" for a LOT of money online that I decided to get it down ONE MORE TIME and: what do you know! I finally found the problem! So, I followed my own advice in not giving up. It sounds amazing and, I FINALLY got it to work perfectly.
Patience and well, some troubleshooting skills I learned along the way.

This has been a super-informative thread, and I wish I had found it earlier. I thought I'd share some of the issues I had getting mine going. It seemed to (mostly) work first try, though the bulbs were oscillating, I was getting no phasing. I found the relay sub I had used (255-1079 from Digi-Key) had reverse polarity on the coil pins, so I did a wire flip between the relay and the board. I couldn't readily find the proper relay (though now from another thread I see an Axicom/TE V23105A5403A201 is supposed to work). I had a hard time finding the proper fuse holders here in the US initially, but I did find also from Digi-key, F6245, perfect fit. I also had no oscillator period adjustment, until I placed the shunt I had forgotten. I used the Adafruit 485-161 photoresistors. I don't think they have the same dark-resistance as the originals, but I put them in sockets so I can try others. I went with the internal power supply, and used a 36 volt center-tapped 500 mA toroidal transformer. The case is an LMB MDC-973. With the board mounted to the top, it's a really tight fit at the front for one of the bulbs (which I had to take the base off of to shorten), and some of the heat sinks. If I had it to do over again, I'd mount the board on the bottom cover, and remote the pots.

One final thing, just throwing this out there.. if anyone knows where I can get a copy of J. Haible's Dark November, PM me!

This is my exact issue... I'll check out the Relay I am using,
I did a wire flip between the relay and the board
not sure I understand this, but might look out for a recommended relay... anyone got a part number that they know works?

mine has been on the WIP bench for many a year, so woudl be great to get it working.

The part number above works in mine. (TE V23105A5403A201)
Not sure where you are but it’s available from mouser in the US or U.K.

The trick is to use a non-polarized relay so whichever way you energize the coil, the relay switches in the right direction.
