House wiring? (and on-topic again)

Are you the "yes Harry, Tubes!" guy?

Yes, of coarse, the "smoorspoel" in Dutch.
I was more thinking in terms of lightbulbs at the time.

These things have always been explainded to me in terms of odd behaving
diodes, and I didnot fully grasp it, until I started figuring out what
actually happend on a electronlevel. Knowing this, it's easy to see why
this parts die when you do not heng them nicely in resistors.

:-)
I'll messure that.
as for the 9 and 18 volts: 9volts batteries tend to stay alive some 48 hours.
For the relais: max ten are on simultaniously. so, again, that won't be much.
They tend to click though. I already added diodes over the coils, but that
didn't kill all spikes. They are on a separate power supply now, which is
fine.
The 24 volts is now comming from a tiny powersupply. It feeds a lowpass wah
filter.
It will probably suck :-) about twice as much as a normal dunlop wah.
blabla.I'll come up with some numbers.

Thanks!
