You can panelize with KiKit

Shouldn't be a problem - you should be able to set up an exclusion zone to remove it if you're really concerned though

Op-amps typically want to see a bipolar power supply - something like +/-9v (with reference to ground). Just using a 9v battery you only have a unipolar supply (+9v/0, or -9v/0 if you flip the battery), so by using a equal resistive divider you get +9/+4.5/0. If instead of the ground/zero...

Tell me about it :p It's cool for vibes, but absolutely isn't worth it either from a cost or time perspective.

Just cutting tracks? Easy. However the whole process is: cut tracks cut half through-holes cut positioning jig removing board, cutting rear tracks applying UV-cure solder mask to both sides removing solder mask from both faces cutting through-holes all the way through cutting board outline As...

There's barely an offboard connection there that doesn't look like it's got a short, and with that much damage to the PCB I would be shocked if you hadn't got multiple trace issues

NE5532 will easily drive most reverb tanks, and plenty of schematics out there for full send/return circuits with all controls included.

Create your two separate ground planes as nets (ie. I use GND and GNDD just to make life easy). Place a symbol called "Net Tie" on your schematic, and connect the ground to it on opposite sides. Attach a footprint to it - use any of the generic ones (just redesign it to suit once in PCB...

Going off datasheets, you can get away with 2mm if you skip the washer (which matches up to what I've done before with ply faceplates). 1mm doesn't leave a lot of room for a CNC engrave + paint fill, unless I'm using some sort of carrier to keep everything flat (and facing on the CNC again).

I've had an idea for finishing a Duocast enclosure off and I think the easiest way is going to be CNCing an aluminium plate (and filling the etching in with black paint). Has anybody done this, and if so what thickness/etc of aluminium did you use?

2mm aluminium is already very easy to drill - why would you need thinner than that?

Well...no. There's quite a bit of difference between them, and you absolutely can't sub a 5532 for a 5534 without extensively redesigning the circuit - one is a single and one is a dual

Potentially. Post a schematic

My previous job was working on power supplies capable of putting out 52v....with a short current of over 100kA. You had to use fully insulated tools everywhere; not for the risk of electrocution, but because a short would likely turn whatever you were holding directly into plasma and the...

If it is also positive ground, you can't unless you have a fully isolated power supply.
