I spent a lot of money putting together a Nava and ultimately failed. I asked here but never got any support from E-Licktronic. I thought I was just impatient and stupid until I managed to put a Gilbert together in ~15 hours on the first try. E-Licktronic’s PCB quality was to blame. I was not willin...

I had the same problem and noted it on my website: https://derekwarren.net/nava/pages/nava-build-guide-addendum.html#power-supply-and-i-o-board When shopping for a power adapter, ensure the data sheet explicitly states the output is measured in volts AC . A few others have fallen into the same trap ...

Did you accidentally purchase a 15VDC (not AC) power supply like I did? My readings were the same until I bought a 15VAC unit.

They're not immediately visible but they're on the Nava product page => Download tab => top/bottom layout.

And congratulations.

I'll try buying a couple of spare 2SA798s anyway. The schematic for the hi-hat shows the 2SA798 quite a ways after the resistor array, but what do I know about anything. The 2SA798s arrived this week. I swapped them in but neither of them made a difference. :\ The poor Nava build documentation, the...

Ok, printing good. Connections shit. The traces were posted a while back. They're not immediately visible but they're on the Nava product page => Download tab => top/bottom layout. Easier links in my build guide addendum , and why not here as well: Nava 1.01 top layout/traces Nava 1.01 bottom layou...

Yeah, as I found out, there's no use swapping op amps if there's nothing being fed into them. :-) I don't know anything about electronics but I borrowed an oscilloscope and poked around to see how far the signals got before they disappeared. You'll need the schematics . I managed to find a missing s...

Hello, Glad you found my documentation useful. Other, much smarter people have said 16VAC is fine for Yocto. (Sources: [ 1 ] [ 2 ] [ 3 ]) The Yocto power board build instructions say " The transformer must be a 15VAC or 16VAC 1000mA. ", and the Yocto power board seems quite similar to the ...

So I measured both 2SA798 on the two boards in continuity mode with my DMM (I don't have an oscilloscope). The result were completely different values. The measurements I took from a known working 2SA798 (ride/crash) and the hi-hat 2SA798 were similar (680-700). I desoldered the hi-hat 2SA978 and r...

Thanks for replying! For the record, the 2SA798s I have at Q78 and Q68 (crash/ride) seem to be passing voltage on pins 1, 2, 3 and 5. The 2SA798 at Q84 (hi-hat) is passing voltage only on pins 1, 4, and 5. Pin 4 passes more voltage or less voltage depending on whether an open or closed or hihat is p...
