I'm troubleshooting a couple of PT2399 circuits one is the sagan delay the other aleph null special sauce. The Sagan passes only clean signal. and all pt2399 are getting 5.78v. I know the 2399's are supposed to get 5v (the " I know" part is an idiot telling you HE knows something and he just...

Recently re-built an Emma ReeZaFratzitz again . Its been a few years . As with transistors and their varied variables does this apply to IC chips also. Cause I remember my first build being a screaming distortion but this sounds a bit .....less. Are there variations within an IC chips...

Problem pretty much solved. found I had pu 100k instead of 180k for R7 and 220 ohm instead of 220k for R48. now I have some flanging and need to adjust the trimmers. Oh so so very happy.

I've completed my build. I can get a mild flange turning the bias trimpot . Trying to set the clock trimmer I do have a DVM with frequency duty cycle setting. Going to the test point I get a reading but after maybe 5 seconds it goes to zero , thinking I moved the probe off tp.1 i check and get a...

Oh man guess I gotta spend more time here than I already do . Thanks for the heads up

If not then yes something along those lines

Uh oh is that already a thing?

After doing some random reading on this forum I came across a great idea( I think) "I appreciate that! I did pickup those 47u caps a while back from Mouser and just got a bunch of bucket and clock chips from Cabintech. I think I'm ready to go but I'll keep that in mind. It'd be cool to set up a...

Thank you I did try that . I used a 100nf and 220nf but the added small value did not register when tested just gave the same reading without the smaller value

AWESOME!!! Thank you very very much. I knew I had a 50/50 shot at being right about the caps and after I posted it thought "Hmmm I should double check myself..................." that's as far as that thought went. Thanks again. I think I'll socket that spot (just to be sure)

The trimmers , 1 100nf cap and 1 unbelievably problematic .... 5pf cap. I have everthing but the 5 pf cap. What I do have is a couple of options 1 - I have ceramic caps marked 10 that read between 0.072nf to 0.0.052nf on the capacitor setting on my DMM 2 - I have 15pf...

glad to hear that since I had no luck with both the pearl flanger AND the Boss bf-2 which I etched from other's layouts with no luck also the hollis flanger which does'nt sound like a flanger at all to my ears . Thanks for the answer I was hoping to hear and your time given to my question.

I can't seem to find any 25k trimmers for this build ( so far). Can I get away with using a 30 k trim pot? It's the last part I need to complete this one> I wouldn't think there'd be a problem using a 30k since it's a higher rather than lower value. but, .....well that's why I'm here asking...

Is it ok to use tantalums where electrolytics would go, on this build specifically the 1 uf ones?

Got it . Thank you.. That's what I did. For me, DEFINITELY, a circuit needing much more focus on dialing in the trimmers to getting it to sound right. Tweaking the trimmers ever (EVER!) so slightly will change the sound a bit so I'd go back several times adjusting the trimmers. Mine works ...
