As I stated on another thread, I have modified an Eiki ST machine with the HID150 lamp and a Venture ballast. Likewise I have modded the pull-down `still frame`lever with an added aluminium plate to protect the gate.(not the shutter blade) In practice, the `douser is ok for short film stalls, but for much above the 3 minute lamp warm-up time, repeated stalling can cause cam tank bearing or clutch damage. I now intend to mod an NT1 with similar gear. The ballast,fusing together with an hour-meter is located in the hinged back of the machine.The hour meter from Ebay(£3.50) Ballasts are available on Amazon and most electrical suppliers.The ballast price - from £25 and type is Venture VYC150255 (current) or original V150SSC255 (discontinued) but can still be found. Lamp manuacturer states that a `Hot re-strike`possible, but my tests showed that a minimum delay of three mins improved re-strike speed. Some reviews show 1000 hour life, others show 750 hour. Either way, the colour temperature and brilliance on screen together with superb lamp life, make this mod well worthwhile. Following the Eiki NT, will be my trusty B&H TQ1 which was already modded to use the ELC lamp, so updating to HID is straightforward for me. The modification time on the Eiki ST machine was 5 hours, the NT will I think prove similar. With a faster pull-down the NT will give even better light.
