Umpteenth time's the charm?
Single ended amp for the sustainer is just fine. Do Not Omit the Zobel network.
2.5 watt LM380. Auto gain control. Hand wired thingamajig.
12 volt via the guitar cable.
Extra knob for sustainer gain, pushes from pre-oscillation to full self oscillation.

Well, that's a heartbeat. Sure looks better than the Veyz crap. Works better too.
Amp chip isn't even getting warm with the 4 ohm load.

And there's the finished thing minus screws and springs. No need to be fancy, no need to access for service. More Water Weld holds it in *and* reinforces the tabs.
3.9 ohms by my meter.

Cooked one a *little* too long in the wax pot, oops. It will work fine( special toan ?).
That what covers are really good for. Waxed, polyimide tape. Test drop right into the cover.
Soldering and shielding up next.

Take two: always include reverse polarity protection especially if you don't think you need it.
Bonus: tighter = quieter
Also took the (shiddy) paint off of the "driver" because a white accent doesn't look bad. I'll change the truss rod cover back to white too.
