bipolar 303 filter and other bits.

So is the Moog Micromoog... which in my view deserves an award for
having two switchable AD/R envelopes instead of one ADSR a la SH101,
Juno6 and other Roland analogues.

BTW: Thanks for the help with the tube amp. I will get those cathode
resistors in place next time I see it. They sound like a good idea.

On another point, my scope which had a focussing problem, was down to a
dud focus pot. The wiper was not touching the track except at the ends.
Bah, I could have found that one... but I didn't. Never mind, at least I
got to find out another local repair guy who seems a nice chap. Mind you
I am still waiting for the part from Tektronix, which had to be oredered
from the US.
