Absolutely right Tony, Pantechnic was, I believe, the trading name used by Phil Rimmer to market the modules.
I don't think the designs were too far removed from the original Hitachi application notes.
it's all just cardboard and magnets really

I still have a pair of the 800w modules in an amp that I built in the early 80,s.

The OP transistors were never brought into the country by anyone but Phil, which caused me a few problems when later on all 8 devices decided to self destruct.

Ben Duncan no less had a high regard for the circuit topology.

Yes...

@Lewis, do you still have the XD4000?

Any chance you could do a 2.66 ohm stereo test for 40hz?

Also, could you please publish the results for the GPS 3400? LOL

that would equate to as 1.33 ohm load per side of each bridged pair, hardly fair...
