Re: Why 1000pF as opposed to 1nF?

Over the years I've noticed a preference west of the Atlantic to express capacitance only in uF and pF - nF doesn't often get a mention. I would use nF where it's appropriate, i.e. to avoid lots of zeroes one side or the other of a decimal point. In the end, they're the same and imply nothing.

The regulation will be done inside the pedal. This is what our own Synthb...

Re: Build Log for Weston PRO2021

I don't know enough about PSUs to understand why the negative regs need a shim, but the positives don't. Can anyone enlighten me? It's not really a shim, it's an insulator (I think that's probably what you meant). The tab on the positive regulators is ground. The tab on the negative regulators is t...

You may even be liable for paying import taxes again.
You should be able to mark a shipment "for repairs" and not be liable for duties a second time around.

Re: [Order] Roland 100M ADSR fabbed PCBs and 4HP Panels

1) 0.25W (1W will likely be too big to fit physically - electrically it makes no difference) 2) I built mine with whatever I had to hand. I don't believe it makes any difference for this application. 3) any size, standard current (else use a low current and much bigger CLR) 4) the maximum any cap co...

Re: diy module - afraid to plug it in

I have a Joranalogue Test 3 and an FC Power board in a standalone box. It gives me enough of a warm, fuzzy feeling that nothing will die when I transfer my build to a case.

It's definitely a mono jack. A stereo jack would have three lugs (tip, ring, sleeve).
