I’m looking for the illustrated assembly manual for this revision of the kit. The one currently available is for a newer layout. Older revisions of PDFs used to stay on the server but I haven’t been able to find it. Can anyone attach it here or give me a download link? Many thanks.
Kind regards,
JF
PS : I could not open a ticket because I don’t have a Direct Customer ID. As for the shop where I bought the kit, it went bankrupt a long time ago.
Thank you very much for your reply. In fact just before I read your post, I also found the same document was also available here : https://manualzz.com/download/11309917
For anyone wondering, the differences between the two versions of the circuit are :
layout : the triac and the inductor were moved closer to the output terminals in the latest revision
the inductor L1 is now 1 mH instead of 50 µH previously (x20 increase!)
the symbols for the two pots (which are used as variable resistors) are mirrored in the new schematic. This could be either to reverse the rotational direction of the pots (turn clockwise means motor goes faster instead of slower, or vice versa), or to correct a mistake in the schematic, if the layout hasn’t changed (can’t be sure as I don’t have the new PCB at hand)
LED LD1 and resistor R15 were added
otherwise the circuit and component values are the same.
