not yet , ya kwayzee danske ;
I have enough duties regarding our local GB ........... and just when first pcb be tested I can tell that's OK

PSM LS pcbs are on fab , buffer pcbs are still in work

reg for buffer is nothing special , except one little trick ,and even that is boiled water
I'm sorta shy-proud with LS circ ..... buffer reg is trivial

difference between Mk's of Lightspeed is ( at least as I see it ) is that Mk1 is series fixed resistor/LDR to gnd , and Mk2 is LDRs in both positions .....

so - solution here is same as in MK2 and in Papa's version - LDRs in both positions , so just reg is different , with few other tricks in it .

here is different , comparing to Papa's only that we used rather primary current regulator than voltage regulator ..... in fact - there is not much different , but I have impression that this variant is pretty good ;

NB - I didn't analyzed Papa's circ in deep , so I can't tell right now is it current or voltage oriented (even if that's just matter of wiev) ;
I just goes for different solution ...

parallel resistor to lin pot is trick borrowed from Eliot Sound ( his site is treasure indeed)

regarding J309/310 jfets - I'm using them in my

I see them as 2SK170V ...... on steroids
