Univibe (real one) voltages. Clearly shown internal transformer secondaries, which is really close to 20VDC (+/- 19.20 after the diode in line with V+)

With lil human around you there is no risk exaggerationkymar wrote:Actually you are exaggerating the risk.
What about the noise, how noisy is the UV in fact?
With competent arrangement of components shouldn`t be any voltage induction.
This is not only my errors hazard. Fluids around your pedalboard - bear, coffee (tea in UK) washing machine failure, unhappy audience urine, no matter - can kill you if split over your fancy, mains powered opto phaser...
There is no regulator circuits in the walls, voltage always vary depend of the part of the day, or home equipment power consumption. I wouldn't argue about this topic to muchIn Wattson scheme we have 22v after rectifier diode

Found it, quote by RG.Keen
The ones I measured were about 18-19Vdc unregulated, and the R-C sections dropped that down to about 16Vdc on the audio phase line. But there were at least two releases of the PCB, perhaps they had different versions of the power transformer too. The 16Vdc is why I picked a 7815 regulator for the first Neovibes, back in the 90s. I've had lots of testimony from builders over the last decade or so that those duplicate the original Univibe sound if built correctly, even with (only) 15V in the signal line.

That brown Paxolin is dead sexy.....as well as all those carbon comps....
Who did your board....
and where'd you source the resistors ?

ask Brook from http://pigeonfx.com, maybe he will be able to eatch pcb's on paxolin for yadanielzink wrote: That brown Paxolin is dead sexy.....as well as all those carbon comps....

pcb layout is availiable on http://turretboard.org
AB resistors are from ebay - from this seller:
https://www.ebay.com/usr/bigsmythe74
not cheap project, though..

Yep, Brook have my blessing, tons of experience, and load of paxolin to supply half of the world with UV replica boards
Anyway, my entry - 915 spec first
