Tryfelo SPDT switches - On/On and/or On/Off/On?

Hi Stefan,

I was just about to solder a Tryfelo kit when I noticed - unless I've accidentally mixed up some bags along the way, but I don't think so - that while the online BoM (row 35) states that it should include 6x On/Off/On switches, my Pusherman-sourced full kit included 3x On/On and 3x On/Off/On switches?

So, just to make sure before I get to soldering, has this changed - e.g. On/On's are now used for the Wave switches while On/Off/On switches are still used for the Divider switches? - and the BoM should be updated accordingly to reflect this, or is it still recommended to have them all being On/Off/On? (nb. I'm assuming losing the Off position for the Wave switches would just mean having to unplug the cable, switch off or attenuate elsewhere instead, but maybe I'm missing something?)

Thanks in advance,

BR//Karl

Hey again,

If you like you can contact pusherman directly for a replacement of the switches (because they are actually making the kits).

Cheers,

Stefan

PING? :) (see my question below)

Hey Karl, Tryfelo runs through a cycle of about 6V from -3V to +3V. Unfortunately, there is no easy way to add gain or offset to the voltage levels, but I have already noted this for a future revision.

The LEDs are implemented so that they fit the above voltage levels and should light up brightly at the LFO voltage peaks of +3V and -3V.

In fact, the holes for the plastic potentiometers are slightly smaller to accommodate their smaller size. Cheers, Stefan

OK, thanks for clarifying! /Karl

Hey Karl, I have specified ON/OFF/ON in the parts list so that both the wave output and the divider resets can be switched off. It's an easy way to get further control over these. I think Pusherman only added the ON/OFF/ON switches for the divider reset, as you can switch off the LFO waves with the attenuators anyway. So you're good to go! Cheers, Stefan
