Didn't see your question on the power supply.

I found the answer to the power: it needs a bigger power pack, probably something like 1000mA.

I'm not sure yet just how much power the quad chorus will take. It is very likely to be a lot more than the HVM - four BBDs and their drivers banging away at 150kHz will take some current to drive.

... what is the suggested +/- wiring: minus in the middle of the power contact, or is + in the middle more common?

Neither. The RPSU needs an AC output power pack. On a single phase (two wire) wallwart neither of the terminals is a positive or negative as such. They can be wired in any way you chose - but neither should make contact with the metal case directly.

Depending on the power needed by the SE module it is possible that the SE and HVM in the same case will need a more beefier solution than a wallwart power pack. A 1000mA single phase AC power pack will supply around 250mA per rail. That may be pushing it with both the HVM and SE1 in the same case. I think we'll be back to using the Yamaha PA-20 or an internal transformer.

OK, thanks for the power supply feedback.
Once the SE1 is ready, it would be appreciated if you could calculate how much juice is needed from a power pack or an internal transformer.

Tiny word missing in the HVM part list under pots:
The frequency 10k log pot is DUAL.

d'oh! oops
I'll get it fixed in the morning. Sorry about that!

Finished building the HVM. It sounds great! I instantly recognized the sounds from the VP and the Lambda. Subtle changes when flipping the "pitch" and "footage" switches, but still noticeable, especially in the higher register with single sounds, and in the lower part when playing chords. The VP simulation really needs the chorus unit, while I certainly see many uses for the Lambda emulation as it is with its full, warm sound. Just delightful! Very useful eq as well.

I am very pleased to build an Oakley board again. As always it is a pleasure to build, and to follow the builder´s instruction. Curious to build such a large board and have absolutely no trimmers!

So now I am eagerly waiting for the chorus board. And case and front panel. I am still missing two parts for the small power supply, so I just powered the HVM from my modular, and used the bare board lying directly on my bench.

Interested to hear/see a sample!

Hi Tony. Would you happen to have an FPD file or specs on the spacing and sizes of the drill holes for PCB mounted pots, switches & LEDs?

Thanks!

The only thing I've got is the one attached. It should be right but I've not tested it. I will be doing a full 19" wide one as soon as the SE330 is finished.

Excellent thanks! Any idea when the other component and the 19" version will be done?

A good question. Well, the project has sort of grown a bit. Right now, I'm not sure whether the SE330 will fit in a half width rack but I'm going to try. The plan now is not just to replicate the quad ensemble effect of the VP330 but also add to it the Juno chorus, Dimension-D and plenty of variations in between. I'm not saying it'll sound exactly like any of them but the prototype sounds pretty groovy.

The schematic is almost done. Just the output stage to complete and then I'll start laying the board out.

Possibly ready to ship by the end of July?

Wow, so not too far from now. And that is meant to interface with the HVM, right? Might just wait to order my components and build them both at the same time with a single 19" panel.

Actually I would like to order the Multicomp switches if possible for both modules while I'm waiting. Do you know which ones (if any) I'll need for the SE330 circuit?
numbertalk
Same with the pots too, actually, if you know what I'd need for the SE330, since I get those from Futurlec & they take a while.

Thanks!

What I have on the design right now is:

4 of 50Klinear
2 of Dual 50Klinear

1 of 'on-off-on' single pole toggle switch

But... this is all possible to change. So I wouldn't recommend ordering anything just yet.

Tony

Gotcha, thanks.
