Just adding I made one from Mark's schematic, but rearranged to fit in 1590b size (with top jacks) - it sounds amazing Also just tried it at 12v which was nice

This is a great thread! I was using it last night as I redesigned splitting capacitors into smaller ones!

Oh wow - that @Chuck D. Bones thread has all the info I need to right now something up! Thanks @Robert

Look bigger in real life!

25 in a tube so cost me 2p each - if I can’t use them for anything it’s no loss!

So in our village there’s this social enterprise place where leftovers from local industrial stuff gets sold - lots of half rolls of fabric, Perspex with some bits cut out, offcuts of leather and so on - it’s great. Today I went down and got £1 bought me a whole strip (50) of Borns 10k...

Shouldn't they wait till you release the degooped PedalPCB board so they can go "ahha it's not quite the right trace AND we improved it anyway so I fart in your general direction" or whatever they say?

That is very cool 😎

looks good! I've not used the PCBA for electrolytic yet. something to try next time. How do you use the connectors?

You may have meant different files

Look, he’s got a load of things on his shelf to deal with, traces to do and he will get to the build doc files eventually, just give Robert a break!

Google suggests it means “low drop out” and is a step down voltage IC of some kind. Not going to give me +- 15v from a +9v supply

Cheap option get the mini Tonex thing or equivalent and go straight to PA - but I'm a bass player so what do I know?

It feels like the kinda thing I *should* have been able to search for and find out! The Aion L4 preamp I built used one of these rather than a charge pump. One of the times the much maligned Aion daughter board made sense as it was mounted between the foot switches facing up.

will be. I've mostly ended up using musikdings kits of pedalPCB things - upside is less stuff you don't need, the downside is less stuff to breadboard with so weighing up if its worth it vs building another frequency interchange and feeding it more power (option 1 above)

Thanks Chuck! That helps :) Basically the last few months I’ve built both the frequency interchange filter and the skeptical preamp, and liked the sound of one and the headroom of the other (for bass) - my crazy plan I am half thinking of bodging taking the middle filters of the frequency...

Stupid Q follow-up - is there common examples of circuits that need +- voltage vs VREF? And/or where should I be reading up on this to answer them in my own? Google searches show solutions and different power supplies - but less of the whys

Ah ok. So the designer would start off with the power supply and then design the circuit - or start off with the circuit and then build a power supply for it? I realise this is the questions that would be covered in term one lesson one of an electrical engineering course but my google searches...

So I’ve built a load of pedals, Mutron clone, Aion’s L4 preamp PPCBs skeptical buffer who have used bipolar power supply’s. Most others use a monopolar power supply (if that’s what it’s called) +9v and gnd with the vref being fed into the input … I get that bipolar power supply is how older op...

I’ve done pcba before but just done resistors, diodes and some ICs and ceramic caps- always been unsure if film caps can just be switched for mlcc. Have you used JLC PCBA for electrolytic?
