Not a silly question, the original used LF353's, you can use 072's too...

Hey all, my Resonant EQ is working beautifully (even with cheap 082's in it) apart from the 11k band, which doesn't seem to do anything. Any suggestions of which caps/etc. to check for this band?

11k band has two 220p caps, 15k4, 68k and 10k resistors. So that’s the bottom right part when looking from the back. If you’ve used styroflex caps, try touching or slightly moving the caps to see if the band starts working again (put it in feedback mode and turn all bands down and only 11k all the way up, turn your monitoring volume down to avoid hearing damage). The styroflex caps sometimes have bad connections which is why I avoid them. Not really worth the hassle, plus they’re way too big often.

Thanks, I was wondering where to find that circuit diagram! I'm suspecting that the issue is that I used film for all the other caps and, ahem, ceramics for the 220p's... I didn't have any 220p film caps around and I was impatient :hihi:

Also, are polystyrene caps from Mouser "up to par"?


Cheers!
Does anyone know if this is still accurate/adequate?

Edit: Looks like the link I quoted is dead, but here's the one I meant: https://www.mouser.com/ProjectManager/P ... dca4c4a741

I just put in my order, and had to modify the previous cart to replace out of stock components. If anyone can use it, feel free to visit it here:

https://www.mouser.com/ProjectManager/P ... 71896ba491

The following details are worth noting if you're going to use this:
The 4.7nF Styrene caps weren't in stock until January, so I replaced them with C0G caps.
I didn't order any male/female headers, or ferrite beads.
I added pots and knobs to my order.
I went with LM49720 opamps.

Where are the outputs located for the individual band outputs? Do you just hang a jack off of one end of the 1k resistor?

Hi,

Might be a big ask but was just wondering if someone could look over my RES EQ BOM. All of this being stuck inside is proving to be difficult so thought i'd use the time to do this and learn something. Bare in mind i've never ordered anything for myself before. Just looking for a heads up on anything i've maybe missed or anything that's the wrong value. If by any chance it's seeming correct then anyone looking to use it can feel free too :). Ignore the 4x2 female headers, they are for another project.

Here it is - https://www.mouser.co.uk/ProjectManager ... 4127674590

Things i'll be getting else where --

Switch SPDT
6 Thonkiconn Jacks
10 Potentionmeter 50k or 100k linear (B50K or B100K)
3 Potentionmeter 50k or 100k logarithmic (A50K or A100K)
2 10uF Electrolytic
11x IC SOCKETS
1 SIL header 6pol
4 SIL header 4pol
PCB AND PANEL
Euro Ribbon Cable.

Does anybody have a good place to get one of these in the US? Looking around and everyone seems to be out of stock...
It's done!
...probably! Ahhh, who am I kidding...

Well, I bit the bullet and ordered the Tropical Military one from him. No idea when it'll get here as I'm in the US, but if you have any requests for things you want to hear it do I'd be happy to record some clips when it arrives.
I'm pumped. Just looking at pictures of the board makes me happy. Cost a bit since I have to import it... but worth it for sure. :party:

Congrats with your purchase!
A demo of some percussion through it would be helpful, along with pure feedback stuff.

Happy to oblige! Still waiting on it to ship, seems that anything international will be taking some time anyway... here's hoping it gets here fast. It's hard to be patient for something this cool! I'll post up some demos as soon as I get it patched.

Edit: Just received the Dr. Wiener Tropical Military version, very fast shipping! And woooow, this thing is awesome. Thought there was an issue at first but think I just needed to let it warm up and settle in. It's AWESOME. As promised, here's some demos. Basic pings, Amen break processing (without resonance in the first part, and with resonance in the second part) and some straight self-oscillation. Sooo much fun. I'm gonna spend a lot of time with this thing. https://soundcloud.com/uniquepersonno2/ ... OuFNkssxSH
