Waveulator ME Saturator Construction Information
Re: Waveulator ME Saturator Construction Information
GR20, all good! It was indeed the 7805 regulator acting up.

Re: Waveulator ME Saturator Construction Information
Great! Glad you found it with the GR-20.
I'm wondering if R48 could be made 30K (was 49R9) to make the 10K pot span 0 to -2.5V for 0 to +3 dB make-up gain.
I owe us all assembly instructions for the GR20. That's been on my list for over a month now.

Re: Waveulator ME Saturator Construction Information
I got it up and running! Sounds great so far.
I might need to do some small tweaks here and there, but so far I'm really happy with it
I had some brandnew cinemag transformers laying around for years, finally I have use for it. They are on the input and can be bypassed.
They sound really really clean, maybe a bit to clean.
The LED meter has some scratches on it, so I will replace those I hate these things.
For some reason I wanted it to be gold. I think that worked out nicely and kitschy.
And for those wanting the logo, here you go!

Re: Waveulator ME Saturator Construction Information
Nice job!
I love the gold panel and the way the knob's reflection provides a glow around the dial.
I realize that a 12 step switch starting from 0 naturally "goes to 11" but I can't help - particularly with the Waveulator - to crack up laughing as I think of Spinal Tap.
Is the meter running on bar or dot mode from the +15V rail?
If in bar does the 7805 need heatsinking?
Thanks for that logo!

Yes, the gold looks cool for some reason. Normally I'm not a fan of such shiny things, but it just begged for it.
The 7805 is running on the 24v line (with a diode in series wuith some bypass caps) from the meanwell modules pre-regulators (lm317/337).
I was afraid that it would run warm since it had to go from (just under) 24 to 5v, but all good. I also think it's stays cool enough because in practice only like 2 or max 3 leds (so like 1dB) would light up anyway. More then 2dB of GR is not something I would use in pratice. Maybe on some material, but I just racked it up so I don't know for sure yet.
I had to make some mods for the onboard bypass relay since i also had to power the relays for the hard bypass and cinemag bypass which are 12v relays in series, so 24v. I removed the 24v regulator and other parts around it and have it running on 24v directly. The 24v comes from the meanwell (IRM20-24) module which also powers the 7805.
Stepped switches was some work. I ended up using all 10k linear switches with some added resistors here and there (need to check out what I did use in the end). The log for the threshold just didn't work, it was way to course for mastering. Now it's just working in a small range.
Same for ratio, 10k lin with added resitors so that it's only working in a really small range. We are talking mastering, it's subtle (most of the times).
And yes, they go to 11! hahahaha! Actually, I did build a varimu compressor years ago, that even goes louder, it goes to 11 and a half, which is 0.5 louder. loud is good!

Re: Waveulator ME Saturator Construction Information
Finally got around to building mine, still working on wiring it up but finished the panel over the weekend. The second ‘input trafo’ label should be labeled output but I can live with it, lol.
I recently grabbed an Omtech Polar 350 laser engraver (50w C02) and used it for the panel markings. The laser vaporizes andonized aluminum, leaving a really clean mark that requires no additional cleaning or steps after the panel has been engraved (aside from drilling).
Im using a pair of Altec/Peerless 15095’s for the input transformers and a pair of UTC A-20’s on the output but left enough room in the case of either needs to be swapped.
Regarding the pot tapers and DaGooses comments, I may add 2 additional toggle switches to flip between linear and log tapers on the threshold and ratio controls, still contemplating that though.
Anyways, here it is

Re: Waveulator ME Saturator Construction Information
Very nice!
The laser engraving is very clean-looking. The graphic turned out well.
I can't tell from the pic: Does the aluminum underneath look like bare shiny aluminum or does it have an "etched" oxidized crystalline-like texture?

Re: Waveulator ME Saturator Construction Information
It’s bare and shiny, completely even with the panel. It tripped me out the first time I used this material. Ive always had to do a lot more work to bring elements out after it’s engraved (infill, multiple washes, etc), it’s done the moment it comes out of the laser.
