Title: Wish me luck...
Post by: Pmebill on August 04, 2022, 01:28:38 AM
Long week is turning into a much longer one!

I've taken it upon myself to build NINE projects from Dead End Fx. Now, building boards is not exactly a foreign concept to me - my day job is PCB/hardware design + assemby... and yes, 20 years ago, I used to design & build amps & effects.

Now, I'm just building all of these for personal use. Sadly, the first 2 I've assembled have been duds! "Exciterator" (compressor) and "Meta Morph" (Reverb). The Comp is getting no thru-signal when powered on, whereas the Reverb gets thru-signal on & off, but no layered effect.

Not fishing for "no info given" assistance just yet - I've got a day or two of issue-hunting yet to go before I cry for help (but beware - it MAY happen :icon_frown: ).

Happy to finally be on these boards & hopefully I can give back to the community as much as I ask to take away.

Regards,
Bill

Welcome, Bill.  If you need to, check out the sticky "Debugging" thread.  Good luck.

...and don't overheat the solder lugs on those stompswitches and toggles.

Kinda (sorta, not really) update:

Compressor still giving "power", but cuts signal when "on".

Reverb still giving "power", but no applied effect (just thru-put). Now, this Reverb has me wondering...  yes, I did mess up & install the resistor arrays backwards, but that appears to have caused no chain-reaction issue. That fixed, I still have an odd voltage. Aside from the 9v mains, I have: V3=9v, V2=9v, V1=1.2v ... it's that last one that worries me. I (think) I've attached the image to this reply (fingers crossed). Just the part of the circuit that has me most immediately concerned. Still more digging to do 😁.

PS: I did build a 3rd DEFX unit (Delay - based on the EM5) & it turned out great - so I'm not completely crazy nor incapable.
