Sweet control layout and meters. Shiny too.
At 75 & 100 wpc into 8 and 4 ohms respectively, I'm not certain whether the McIntosh MAC4200 meets the OP's criterion for "high power" however production was only 1,189 units.
One interesting characteristic of the MAC4200 is that it's designed for the simultaneous operation of three speaker pairs for a total load down to 2 ohm. As far as I'm aware, no receiver from any other manufacturer has this ability.

Very nice looking piece might I add. 2 ohm stable brings watts up to 125-150 wpc. Nearly $3000 in 1985 too!

Any idea how many Stereotech 1200's were made?At 75 & 100 wpc into 8 and 4 ohms respectively, I'm not certain whether the McIntosh MAC4200 meets the OP's criterion for "high power" however production was only 1,189 units.

I suspect they should be included.
Receiver-Class A II Fisher RS-Z1 receiver 100 watts ch, .007 THD. @ 8 ohms , 150 watts ch , .015 THD. @ 4 ohms.Damping Factor 60, Toslink optical digital audio inputs and 75 ohm coax digital input, Burr Brown 48 kHz internal DAC. IMO this receiver offers the best of both worlds, vintage amplification and modern digital connectivity. This 1989 receiver was TOTL and the last of the Fisher high end products. I have yet to find another one on any other audio forums or for sale.

Well I suspect the ST1200 wouldn't qualify as a "high powered" receiver acc to the OP's criteria.
However, I did check Berner's McIntosh site but apparently the production figure for that model is undetermined.
You pose a very good question. Unfortunately McIntosh didn't provide a 2 ohm rating for the MAC4200 but given Mc's typically conservative output ratings, your estimation may not be all that far off, at least not for short term peaks.

I've seen a few of those on ebay,looks pretty nice.

Gimpus Stereophilus!
McIntosh power ratings are the same regardless of load, unless they are direct coupled. Autoformers, is why. Also, Autoformers are your best friend, they keep DC out of your speakers if the amplifier develops a problem. They save you money.

Try to keep up please.
Only exception to this that I'm aware of are the MC754 & MAC4300 that are rated at 100 wpc into 8 and 4 ohms which are also DC (non Autoformer) amplifiers. I do believe these also have built in circuitry to prevent DC from appearing at the outputs.
