Re: [TCML] 555 timer

[bunnykiller <bunnikillr@xxxxxxx>]

i figured it and came to the conclusion that the good'ole 3055 was easy 
to use...  all you needed was a limiting resistor, a pot, and a 
voltage/current and you have it!
try doing that with an IGBT..  and MOTS ( not the trannie type) static 
charges are always fun to deal with when handling them, but I must admit 
they have gotten better at designing them to avoid the problem.

just a thought... ya know, Ive never seen a linear pass bank made with 
Mots, any one here seen such a monster?
