I've studied the Robot (aka; "Bad Robot", "Roboto", etc) circuit and found at its heart is the HT8950 (18-pin) chip. I've scoured the datasheet for this chip and find that there are two variants: the "HT8950" (with 18-pins) and the "HT8950A" (with 16-pins). Both chips do the same thing except...

The ES56028S is a clone of the PT2398. You can reliable sellers on eBay for either - just check their stats & reviews.

Mouser offers Grayhill stop-adjustable rotary switches in several configurations. The price is a good bit steeper and the connections, footprint & drills are different. They are also a far sturdier rotary.

The EHX Small Clone is probably my favorite chorus circuit to build. Good mod potential too. Nice work!

Fair enough DL. Thanks! Now that I've futz'd with it more bit, I can hear what you described. I just had to adjust the Pots more to get the switching to actuate.

Sure thing DL. For one, can't get the Ambience block to produce an ambient-like effect. Sounds more like tiny tank. Do you have an example?

Wow! All these changes and additions are definitely pumping new life into SpinCAD Designer. Loving the new features. So much more to explore, learn and play with.

This is excellent info! Thanks DL!

If any components do not fit snuggly in any sockets, you can gently wrinkle the legs a bit so they do fit snug.

No. That LED is the bypass LED. On this Moonshot build, there are two locations to place the bypass LED. The other one is at the bottom of the board. The one at the top of the board has nothing to do with the 1N5817 Schottky protection diode. Wire the diode so it can be mounted to the...

The chips not damaged - unless any of the legs are broken off. If no legs are broken off, just straighten them and it'll be fine.

The Rockman X100 chorus circuit generally operates with a delay range of approximately 20–24ms or modulated around 17–23ms, designed to produce a wide stereo image.

Not being a true engineer, I was surmising pretty much the same thing, but wanted to ask. Thanks!

How critical are the existing values of P2 & R2? Can P2 be up'd to 50K? That (by the equation) would make the 100pF cap's value change up to 4n6. Or is C2's value the only component that can be futz'd with? How about R2 - can it be lowered? I'm trying to sort out this circuit is best balanced.

Thanks DL!

DL - what are the "S/O Clamp Tri", "S/O Clamp Sine", "S/O Range Tri" & "S/O Range Sine" blocks in the 'phaser-modulation-test.spcdj' patch? I seem unable to find them on the menu in the 1069 release. Are those just part of a special test?

I believe it should go to the top side of the SLAM resistor - or the other side of the resistor in your image.

You an use an electrolytic cap. Just keep the + side pointed towards the more positive voltage direction. Glad you're trying additional options. (y)

TBH, I'm not entirely sure if it should go to ground or directly across the resistor without testing it. And testing it will not hurt anything - whether it works or not. It's a shot in the dark, but should work in theory, one way or the other.

Try adding a 10µF across that 390Ω resistor. That should slow down the rise and fall of the slam effect.
