You're talking about the secondary machining required for assembly...
the heat sinks were from an outside supplier, they brought them in bulk
and cut them there. many amp mfr's did this in house, some still do. I
remember touring the Zapco facility in Modesto back in the 80's after
they had just acquired a big machine for milling and tapping holes, etc.
- they had been doing it by hand with a drill press before that!

Still has nothing to do with PPI ... if it would help, I could call a
buddy that worked in the metal shop and drove a forklift around the
place before he moved into the front office, and ask him what flavor of
crack you might be on... or, maybe a couple of the speaker designers
that worked there as well.

Linar Power, (also known as Eye Candy amps) amps looked nothing like it Orion,
they had full rap around fins on their heats sinks with stainless steel end
plates. They also had/ have their heatsinks drilled out on the inside to fit
the metal bi-polor trasistors that they use.

Doubt it or not, The fact is that Orion had their own tool shop and their hand
crafted heatsinks made right in their Tempe AZ plant. Just in case you didn't
know the heatsinks came in four colors. Black, SX, Red HCCA and custom chrome
or gold plated with the option of having your name engraved.

And Linear Power had amps that looked like that too. Big deal. I also
doubt Orio was making their own heatsinks. Almost everyone, even today,
buys them from a 3rd party.
