LT1021-7 is worth trying – in LTspice it acts like LT1021-10 and LT1236-10.
The LED TLMS1100 is a tiny thing and personally I think that’s the most tricky part to handle and solder. I started to use it in battery daughter board for T2 and I did buy a hundred pieces right away. It might be a good idea to buy some extra in case if you lose one (on floor, overheat when solder or what so ever). Now days I solder in the LED first and then check it with DMM in diode test mode, positive test pin on anode and negative on cathode and the LED will glow if everything is right (no guarantee for bad soldering though - by own experience). It will not glow with transistor and resistors in place.

Colin's example was the most picturesque, b/c, I mean...
This a better view?

The main board does not need to be assembled but the regulator modules do (2 per power supply).
For the Power supply modules, using the LT1236 should reduce the heat on the CCS pad feeding the reference by about 5 deg C.
I haven't tested this yet, but it seems like a good substitute and possibly preferable.
PS - Just thinking out loud, the LT1021-7 might be the best option here.
looks like I'm the one that caused trouble, not you....
those sinks above are much bigger than mine.
you should be fine but do watch temps and measure across the 100r if you want to know what its running at ...
my board is a direct copy of Dr Gilmore's layout and values.
so all credit goes to him.
I saw no need to make resistor value changes.
Some things can be adjusted as Michael did but with enough heat sink it works just fine as is.
A stable temp is good if you want stable current through the output stage
think mine were about 18ma warmed up on 400v rails
I have two working amps and no plans to mess with them.
Thanks
Cool that you have the mount for your iPad and can drop it in any time you want to. Great outdoor solution. See what you mean about the shadows. In the first pic the board without darts looks positively bright. But I think you probably need to hit it from at least 3 directions, which then creates a logistical nightmare in terms of where to mount them. Like you say this is why the ring lights are a thing, although they really look odd to me - every single one I've seen. Trade offs.

Choices. I think I'll have the chocolate star.
First, put a star in every dimple.
Then add the chocolate batter.
Cook to perfection
Set in shape.
And Enjoy!
