D-Tap Requests:
I will make a D-Tap cable if your plate has a 12V regulated output. Typical V-mount battery systems are in the 11-17V range. A fully-charged 14.8V battery can approach 17V. Bolex electronics are designed for 11-13.5V (Ni-CD batteries), and most work in the 11-15V range. Attaching unregulated D-Tap output to Bolex electronics usually blows fuses and may damage them.
Some Bolex EL functions are not ensured beyond 13.5V according to the user manual. The EL MKI manual shows 16.5V max; however, Bolex reduced the limit to 15V for MKII-MKIII because owners blew fuses at higher voltages.
