Re: What wires for Nava.

For the power wires I re-used the wiring of an ATX power supply out of an old PC. The black/red/yellow/orange one

For the other connections I purchased this online: http://www.conrad.be/ce/nl/product/0685 ... ggest=true

Re: PSU requirements: can I use a 16V AC wall-wart?

Confirmed.

Besides the minimum 1A, make sure it is AC! You won't be the first.. :D

Re: Building IO Board - Measuring wrong voltages

You are sure your power supply (adapter) is an AC one?
Min 16V and 1A AC

Re: Kacper Case Standoff Mounts Broken

Hi, Glueing, I could see maybe done with two component epoxy and then maybe the metal version. But I doubt it will last. Welding, whether steel or aluminium will destroy your front panel silkscreen. Leaving indeed, standoffs with screw though the front. If you're lucky the screws protrude at places ...

Re: MidTom section not working

Considering the behaviour of VR15 and it being connected to IC23, a quick check would be to swap out that 5218 with one from another instrument.

Re: ic m5218 and transistor 2 sd1469 orientation

Hi, The m5218 will have a vertical line printed towards one side. That would indicate the side of pin 1. On the pcb pin 1 is indicated by "1" and a square shape on the silkscreen. The 2SD1469 has a little notch on the top, which corresponds to the marking on the pcb silkscreen. you can als...

Re: Nava v1.02 clap problem!

Or the 2sa798 matched pair transistor?

If your HiHat is working, take the one from there and put it in your clap to test.

Re: NAVA 909 v1.02 HARDWARE BUGS / FIXES

Hi, v1.02 had all pcb issues fixed as far as I know. Myself, I have one of the first v1.0 boards, which had indeed some minor issues, but nothing deal breaking. I didn't even cut my pcb up. Only swapped some transistor collector/emitter pairs. For the rest, I had a faulty 2sa798. Also that is surviv...
