I've used both of these when I worked for Hitachi...better than anything I've used since.

Does this happen with other BBD's?  How sure are you about these MN3008's? Have any pics and voltages?

Did the mod with a On/Off/On switch with OA126's and 1S1588's, and the center position taking the whole mod out of the circuit.  I put in a 4K7 in R9 but I think I'm going to have to put in a 10K just like the OP because I'm still getting a little too much hair and borderline oscillation. 

I gotta say though, I love it.  This is my favorite OD, and I feel silly for not getting the K1 and building it a long time ago. 

I also just added in the "Thick" switch like on the SKII but haven't got to play around with it too much yet.  Seems subtle but more effective on certain settings.  Everybody should build this bad boy

What's the voltages on the compander? Sounds kinda like what I was going through.  I had some parts in that weren't supposed to be for my BBD's, and compander voltages were way off

Anybody have the K1 schematic? I was wanting to do this too.

Edit: good grief, it's on the projects page, my bad

Got mine, they were bagged up and holding onto each other for dear life. Fired right up and looked brand new though.

I'd like to know how the "mode" switch is implemented in the circuit and if it could be used on the ABDLX.

Waiting to see if they work then I'm gonna order some too. Plastic baggy? Really?

Bret, I bought 40 LDR's from Tayda just to make sure I could match some, I've got about 8 more that are very close and I can send you the 6 for this project. No charge just let me know

Well, I started the reflow party, about halfway into it I noticed a little teeny tiny "c" hair of a bridge.  I think that's what it was anyway.  I reflowed it and cleaned everything, socketed the diodes and put new ones in.  BOOM, working great and sounding amazing. 

Reflowing and looking for the smallest bridge seems to always help me successfully complete etched boards.  I also learned that I can get away with using a lot less solder and still get a nice fillet. 

Thanks so much for your help guys.  I'm really excited with this being my first phaser.  I took a break from troubleshooting this the other day, and built a demo tape fuzz, (also etched by haberdasher), and that bad boy fired up first time.  Hab does great work and I highly recommend hitting him up for your etching needs.

I've got all TL072's in there now. I've swapped out different ones because some were from Tayda and I was worried about them.  I've even popped in some TL062's to try

I think I saw where Brian used electros, and Rej used tants?....so I thought I'd try the ones I had.  My next plan is a reflow party, and the whole board is invited.

Bret, I couldn't find a bad resistor anywhere. 

Bad cap maybe? When I try to hook up the  rate indicator LED it stops blinking and stays lit, the yellow one does the same then. I think I'll swap out the diodes next just to make sure about those, and socket them.

Thanks guys, that's my next little journey for this.  Hab, how were you able to adjust that?

I just had the LT1054 in there for a sec while I was troubleshooting, but took it back out.  Tried reflowing everything and still have the pause.
