I seem to be using a lot of these recently, they're just really handy for valve stuff.
I was just wondering if an uber road rage would be something that anyone else was interested in. ie a charge pump that depending on the number of cap/diodes you fit can supply various different voltages up to, say 80v?
I suppose it's only something you'd use in valve projects though, so probably limited appeal :-\
I think it would be cool to have that option. I was thinking about doing something like that on perf in the range of 36-48 volts for pedals that use amp topology with fets instead of tube triodes. I thought it might give some good headroom and dynamics.
