KIts supplied are nothing like those shown in the advert. No pots, just a trimpot; no switch and no LED. Component markings on the pcb are good except orientation of the output transistor is unclear - had to look up the data sheet. It would have been useful to have an instruction sheet. I have made up two of the five kits. Neither work. Output transistor gets hot very quickly.
