Re: Guyatone - PS-014 Delay [schematic]

HI there folks! I Have one of these for repair.. Could anyone post some pics of the wiring? Or somekind of schemtic for it? Some guy destroyed this one, has all the wires broken or soldered to the wrong place... I've followed the schematic, but just wanted to be shure its ok. At the moment, it turns...

Re: TC Electronic - Spark Booster [traced]

I'll look for it... but i'm using a PCB, designed directly from the schematic.
I'll analyse it further! :)

thanks for the input.

Re: TC Electronic - Spark Booster [traced]

Great Work!!
I'm glad to finally contribute to this community, that helped me so many times!

When I built mine.. and despite the fact it already has 1M resistor on the Input, and 100K on the output.. It still makes a very loud Pop noise using a regular truebypass wiring..
Any ideas?

Cheers!

Could you explain, or show the math?

Re: TC Electronic - Spark Booster [traced]

By the way..

What do you think about the active filter section?

Any Idea on how to calculate the corner frequency for each of the switch positions?

Re: TC Electronic - Spark Booster [traced]

So, I've rearranged my schematic, according to your version, and here it goes!! Full schematic (minus truebypass switching, that uses an optocoupler similar to the voodoo lab circuitry). I'll test it tomorrow, to see if it's finally 100% working! I've changed the two cap's for the correct value and ...

Re: TC Electronic - Spark Booster [traced]

Hey Coldcraft! Thanks for your schem!! ;) Great work! A few questions.. For the VR, we can simply use a regular voltage divider? On my schematic, I've got 220 nF for C41... you used 1uF (C12).. any particular reason for that exchange? Also, you use 1K on R17, when the original one was 47K, any reaso...

Re: TC Electronic - Spark Booster [traced]

Hello miklax! Is there a way that you could post some Guts to help in the trace? Thanks! I've uploaded some pic's I've taken prior and after the initial IC-Swap. (I wanted to fit some OPA2134's in there). Don't know if they will be any good for this.. Dropbox Folder Also, I've realized that two of ...

Re: TC Electronic - Spark Booster [traced]

Wellll... I've re-verified the schematic, and my first version is correct, at least regarding the connection I thought it was wrong..
I'm missing something for shure!!!

Re: TC Electronic - Spark Booster [traced]

Hi there!

I've found a little bug on my schematic!! :)

I'll update the corrected one! It was on the R67 connection.
I think its 100% now... will see tomorow.
By the way, there are many components i've ignored, as they are not present in this pedal, or are used for TC's bypass scheme..

Cheers!

TC Electronic - Spark Booster [traced]

Hi there friends, I've received a faulty Spark booster for repairs, and after trying everything I could imagine, and with no success, along with my client, we've decided I should take apart, trace it and build a new one. I've traced it, and already build it, but the resulting boost is not very notic...

Re: EH - Zipper

Hi there people.... I've allready fix it... It was a bad solder on one of the wires, almost undetectable. The pedal is very complex and I couldnt take any decent pictures of it, because of the number of components in there.. One thing that I think is funny.... it has a 3pdt switch, but it only works...
