NICKS:
Well, I'll ask him, but I don't think he'll be very keen. Uh, he's already got one, you see.
ARTHUR:
What?
GALAHAD:
He says they've already got one!
ARTHUR:
Are you sure he's got one?
NICKS:
Oh, yes. It's very nice-a.
It worked for >25 years but with a glitch in the sawtooth oscillator so I started changing stuff, particularly in the PSU regulation area which was a bit of a bodge in the first place. I eventually discovered the glitch was due to a 1M resistor that had decided to be a VDR, but now the changes I've made to "correct" the PSU circuitry result in motorboating at certain settings.
