Recklessly interfering with Darwin’s natural selection process, thereby extending the life cycle of dim-witted ignorami; thus perpetuating and magnifying the danger to us all, by enabling them to breed and walk amongst us, our children and loved ones.

Very good .. manufacturer, model and version ?
I'll give you a clue ... its not a Collins 51J4U
They did start out using a he-ne inside the prop, but the 10mW output from the Spectra-Physics or Perkin Elmer laser available at the time was obviously too dim. They used a cutting torch from underneath and added the beam effect in post production.

Well done sir! spot on!
A british version of the Collins, and an absolutel classic high quality valve based comms receiver.
Built by Racal, who succesfully won a contract to produce them for the military, to a spec written around the COllins rx, which Racal won on price .. except, Collins refused to sell them a licence to make it... they had to re-design from the ground up, but the result was a world-beater.

I always remember travelling up the A3 into London and seeing the Racal building. Had no idea what they did, but sure knew they existed! Now I have half a clue

You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.

Heh - looks like the steroids-pumped cousin of the SP 265/7 PSU...
..ya gotta luv old-skool electronics, tho...I betcha Bob (Eidetic) could post-up a torrent of crazyarse-lookin pix of old-skool PSUs / controllers, that would look right at home in Goldfingers' lair...
cheers..

I'll post this one. It's a 1968 Hughes model 3052 argon laser I got from Mariomaster here with transportation help from DSLI Jon. Vacuum tubes inside the supply. The outer casing of the head is the resonator! Love the spiral inside the reservoir tube.
And one more, the 1962 Perkin Elmer / Spectra-Physics model 110. This was the first commercial laser with a visible CW beam. The power supply is at the lower left, and the inline control with a start button and RF level knob is also visible. The laser head is the square box with cylindrical end covers on the Gaertner rail. This picture is in a few early books and articles about lasers, and shows a TV transmission demo. I'd LOVE to find one of these supplies to go with the head and inline control I have.

It's all very scientific.
