ABDUCTOR II DELAY.

[Colman]

Ok,checked your post about the short, sorry about being so thick,I don't get where the short is ,is it a sold blob or is it a trace on the pcb itself?,maybe we have a different pcb cause I don't have so many wires,I have the output next to the ground but nowhere to put the blue wire you have there and my out and G holes are on the edge of the pcb,you have more below them.In any case how did you get rid of the short ,did you resolder the wires or cut a trace?
Thanks

Sounds like your pcb is later than mine so the problem has been fixed.

If you look at the pcb track below the red wire on mine, you should notice where the thin pcb trace joins to ground (black wire) I had to cut the little bridges on either side, then rejoin the earth with a separate wire.

To fix the issue, Deadastronaut will have had to shuffle the wire pads around a bit so, if yours looks different, it must be post fix and I'm worrying you for nothing. Sorry.

Edit: my close up picture shows the board on the underside of the volume pot connections.  You can just make out a jumper wire reconnecting the earth in the full picture

Thanks stallik ,you have been invaluable help, cheers man.

The little holes are pathways that join the front tracks to the rear on double sided boards. I'm sure they have a proper name...


Edit: apparently, they're called 'through holes' . Pretty obvious name I suppose

"via's", pardon the apostrophe.

Guys I had to use a few ceramic caps namely all the 103s ,hope that's not going to screw this up.
This hobby/obsession is for younger people  my eyes are not what they used to be  but I have to admit my pulse is rather steady on the soldering iron.Also it helped that the board has generous space between holes so you are less prone to make a mess.I hope this works for me.Thanks again for all the help.

I still have to solder the lytics,I had to take a break, pots jacks and additional wiring.
I think Im going to test it before I box it tho'h and also forgot to wire the LEDs and of course have to install chips and transistors,jfet and 78L05.
Wish me luck.

The order in which the wires got connected to the fsw is left to right on the board and top to bottom on the sw on one side ,correct? Square pad goes to top of the sw ,middle pad to middle sw and last pad to the bottom sw?. Thanks and sorry for the stoopid question. Do I have to get the signal out from the volume pot or the output pad on the pcb?

I just have to install LEDs and I'm as ready as I'm going to be to test,I haven't done so much wiring since the sans amp GT2.I hope it works ,Triple checked but my experience tells me there's always something.

OK.It works but by the love of God I can't dial a usable setting, the sound is amazing but I can only get ambient delays, can somebody tell me how to dial a basic delay as a start point 
Aharon

[stallik]

Turn pots 2, 3 & 4 to zero. You now have a single delay, controlled by the bottom line of pots.

[Colman]

Thanks again stallik.

OK.I think because I connected the pots via wires when I boxed the abductor my pot sequence got mixed up so I no longer know exactly what is what.
I know Volume (haha), depth, labeled speed as delay so I no longer get confused.My feed knob makes the lfo  LED change speed so I think that's not feed its time.what does feed do anyway?
All my pt2399 chips work but when I switch to long delay it sounds like I dropped the box down the stairs all kinds of clanking noise.
Any ideas?
All else peachy/keen sounds awesome and not noisy at all except with speed (delay) all the way CW.
Thanks in advance.
PS:thanks Dead Astronaut for a fine project.

Feed is short for feedback - the number of delay repeats.
The pot you've got labeled as feed is changing the led speed. That makes it speed - the oscillator speed.

When you state that you get the clanking noise when switching to the longer delay time, do you mean a one off noise when switching or is it continuous on one setting?

I would recommend opening the enclosure and checking which pots are which and labelling them correctly. Then, adjustments would make more sense. Not knowing what each control does may lead you to some interesting sounds  just difficult to reproduce

[Colman]

Thanks stallik , without your coaching this build would not have been possible for me.
The noise is continuous like when you turn off an amplifier but it doesn't stop.
thanks
