Perhaps the info was wrong? Anyway, you can always rig up a DIY power supply using a cord run tru hole in your flash's battery door. Or install a new connector from "radioshack" or whatever in the batterydoor, and from the connector run wires to a wooden or plastic block fake "batteries" which contact the flash contacts. Use a lockable connector! From that run a coiled wire of about 0.5-0.75mm internal dia (metric standard), not less, to the battery pack you made. Use same number of cells you put into the flash, just use way bigger sized :) like C or even D cells (if you have deep pockets there are BIG "F" sized cells which hold up to 10 000 mAh in NiCd version! But cost a LOT). Or use a heavy but full of power modern Pb battery - but there could be problem with the voltage difference. You could even get the battery comp. door from Pentax as a spare part, so you don't ruin your flash's resale value :) Good light, Frantisek Vlcek - This message is from the Pentax-Discuss Mail List.
