Thanks. I was able to source the 4448 on ebay here https://www.ebay.com/itm/112289051061 and another part I could not find I also had to source on ebay https://www.ebay.com/itm/254609384506

Just find it super super odd that neither places carry a 19k? why is a 19k considered an odd or non normal value? so just leg any combo of 2 resistors together that add up to 19K and have one funky looking spot on board? If I choose to put an 18K or a 20K in place of the 19K, what is the...

wtf with no 19k resistor at stompbox or tayda.. ODD!!

https://docs.pedalpcb.com/project/GaussDrive.pdf On the GAUSS DRIVE, is this a TYPO on the DIODE of 1N4448 or is that correct? I am not finding those on tayda or stompboxparts. Found on eBay the 1N4448 So here is an odd one.. I am almost done, but I cannot find a 19kohm resistor...

Holy wow. Thank u!!!

Thanks for all the feedback

Interesting... Bc413c looks to have similar if not more "gain" than bc550c. I'm still a noob to pedal builds so my amateur guess is that this specific transistor would have a pretty huge impact on how the ISOCELES sounds, yes? I read in the ISOCELES review some dude said his output was...

Sweet.,, I will send you my addy! And that link you sent is for a BC550B which I can find - it is the BC550C that I cannot find except for eBay in larger quantities and high ship.

Some mega impressive setups here, fellas! Here is my little area of zen. I have a gigantic workshop / wrap around work benches and loads of pegboard and tools and such out in my garage for bigger work but with arizona getting to 120 degrees I needed to make a mini area for pedals and light...

Hehe. Yes, sir. I edited my post after posting to add that I would be socketing. I am nerding out on some specs and see on DIGI KEY some very easy to read "GAIN" info. BC550C says DC Current Gain (hFE) (Min) @ Ic, Vce 420 @ 2mA, 5V BC547B says DC Current Gain (hFE) (Min) @ Ic, Vce 200...

Alright.. I will go with a 2N5089 vs. the BC550C. Seems the BC550C is an older one and is no longer made and harder to find. I will socket the thing so I can mess around with others. This ISOCELES is proving hard to find a few parts for. I ordered 5 new PCB's and am making a motherlode...

"BC550C are low-noise, high gain NPN silicon transistors in a TO-92 package. 2N5088, 2N5089 & 2N5210 are all good replacements. The BC550C is rated for 45V, 2N5210 is rated for 50V, the others are rated for 35V. Should make no difference in 99% of the pedals we would build. One other thing to...

Anyone have an extra BC550C or know where to source one without crazy shipping or quantity? Or can I sub it with something? Doing the ISOCELES bom now

OK, thanks. I will keep using the regular PCB IO non buff. I just ordered 5 more PCB's do to 5 more builds! =)

I have been using the non buffered ones. how do i know if a pedal is buffered or not? i mostly build boost/od/dist pedals and am going to buy about 7 more PCB's. are any buffered boosts going to state they are buffered somewhere?

It is still connected to the board. not able to fix the tap tempo button it seems. i will keep trying. i think the switch is OK so the issue lies elswhere. sure is hard to t shoot with no schematic!

While waiting on my SMD SOT23 NPN transistors to arrive from ebay, I want to try and fix the non working tap tempo button. What am I doing with my DMM on this push button to test it? As a guess, I put my DMM probes onto each tab. Reads 3.2Kohm when not pushed, and 000.2kOhm when pushed and...

Check out the MOOER RADAR.

Don't skimp on the goods, buy the good stuff. Spend the money where it is needed and don't try to save a few bucks. I have an XTRONIC but HAKKO is also great. I have been doing electronics and soldering for 30 years but only started doing pedals 2 months ago and have already built 5 with...

You mean you know the name of Bernardduur from 2012? PJS - Thanks for the tips. I will be doing precisely all that! I spoiled myself with a new X-Tronic iron when I started doing pedals and have a super fine tip that I use for PCB. I also have a Radio Shack mag glass/light that I have had...
