PT80 problem please help, no repeats

[Wales]

So no my only problem is not that only have one reapeat. The sound of the device now is same dry as effected ( no delay ) i didn't get to probe the circut tonight cause my small amp needs a new 6V6GT tube and I haven't got one yet so I can't probe a circut threw my other amp it's just too loud for the neighbours. Yeah I read the posts about some DMM having a built in resistor so that the pin five reads less than it should cause of the 1M resistor being a better path. I guess I can forget about the 0.02V on the ground but I haven't had this on any other build. I'll double check the solders to the negative rail, again! Sometimes you just need time away from it to see what you are missing so I am praying for that.  I'll post again tomorrow when I've found something(fingers crossed)

So now that I have probed the circut I have found that the circut is working okay. I get a delayed signal coming in from L2 and going threw the 1uf cap but then the signal is no longer delayed after the 10k resistor.  So here I go to check around the output and the TL072

So I found a tiny catch between pins one and two of my opamp, I couldn't even see it with my magnifying glass I just ran a knife between then and felt a catch.  The pedal works now, but if I turn the repeats up all the way up it just squeals with feedback. Has anyone else had this problem? I going to check old posts but if anyone remembers an old post about this I'd love to hear about it. thanks for all the help so far.

Never mind just found Mark Hammers mods.

Once again thanks for all the help everyone!

Hi
Congratulations my friend. The Easter bunny came to you too, and with a delayed egg  (or was it De Layed) 

I know exactly how you feel. The agony when you know that you are 100% sure that all components are in the right place with the right value and still,...the shitty thing won't work
You have been over your board with the magnefiing glasses on for hours but still nothing . And you have done your testing and fond that some ware around component X the blasted ting stopps to work. And you are about to start exchanging components that might be faulty. But where to start. And all of a sudden. By a hunch you try one more thing and YES YES YES. (Se my first post about the trace)

A statement to the world.  Wales  V.s  Murphy's Law 1-0

About the runaway delays. If i dial in the repeate over 75% the thing goes heywhilde. I get runaway repeates that escalates in level and get more distorted fore each repeate until its unbearable. First i saw this as an error but after that I've learned to use it. I hook the up the effect as a send-return in my mixer and use it as a post mix. You can really cool mixes if yo do say one slight distorted cord that let it run trough the delay a couple of times and get louder and more distorted for each time and then after the crescendo you kill it.

Well done Wales!

It's funny, sometimes you get people with delays that don't go into infinite repeats asking how they can mod their pedal so that it does go insane!

Glad, to hear all is well.

Enjoy your pedal, I'm sure it will give you lots of enjoyment!

Now my pedal isnt working   It was working fine, volts were correct as I posted to this thread earlier.  I mounted it in a enclosure, led powered up so i assumed everything was good to go.  I lost the effect all together.  So I stopped & checked voltages, and lost my 15 volts coming off the charge pump going to the regulators.  Only had 7.4v.  Checked grounds, & they were showing .03 on pin 3 of charge pump, and .01 pretty much around the rest of the board, & they were all at zero before.  I traced everything, and the only thing I found was it looked like on my dc jack, the pole that connects to the 9volt battery might have been touching the ground pole.  These jacks those 2 poles are really close.  I moved them to make sure there was clearence, and have zero grounds again, however still do not have correct voltages at regulators.  I'm guessing I fried the max1044, it was warm to the touch after I got done reading the voltages.  I have 9 volts going into pin 1 of 1044, from there 7.4 dropping still to 4.98 at 7805 regulator, and dropping to 5.99 at the 7812.  Anyone?  Think I fried the max1044 or have any thoughts on this?  I unfortunately dont have another one to test this theory.

Pick it out to see that you donut have any shorts under/over/ or where ever but from your description a am afraid that you unfortunately are correct in your theory.
