Yes, heater current a bit higher, but we tried when the DAC was at Andrews.

I just read the spec sheet that gave the figure to ambiant as 80C/W, that puts them at 80*75 + 25 = 85C. should be fine, but hotter than I would prefer, YMMV. At 1W them will be at 105W, again, should be still ok as max temp is 150C, But things in semiconductor land migrate at a rate depending on temperature.

On the 10m45s I screw the chip to (usually) the amp case and attach the set resistor and gridstopper resistor to the legs.

Insulated from the chassis, hopefully!
Oh yes indeedy.
I did a bulk buy for the forum some age ago, when Mouser (or the other USA supplier, forget the name) were still supplying them to the UK.
