Crystal Motor for Bolex H-16:

TCS TXM-26C

Superior Flexibility!

Bolex spring-drive cameras (especially those above s/n 100,401 of 1955) are capable of excellent picture quality. The TXM-26C updates your trusty old Bolex (or, a new Super-16 SBM or Rex-5) for the 21st Century and gives multiple crystal speeds built-in. The TXM-26C will drive older model Bolex cameras that only have the 8-frame drive shaft, and also the newest models. The TXM-26C increases camera width by 2.25" and height by .5". Weight is 36 oz.

For Old or Modern H-16's

While newer flat-bottom Bolexes (Rex-3 and up, above s/n 202,501 of 1963) give the most firm attachment, the motor can also be used with fine results with much older cameras. The TXM-26C should fit nearly all clockwork Bolex cameras, except those from the 1940's with an external frame counter. The 8-frame shaft is driven through a flexible coupling.

Five HMI Speeds

Six speeds in all, from 7.5 to 48 FPS (frames per second.) The speeds include 7.5, 12, 15, 24, 30 and 48 fps. All except 48 are HMI Safe for filming without flicker under 60 Hz powered HMI or fluorescent lights. A red sync alarm light shows if speed is lost. Speed accuracy is ±3 ppm or .0003%.
NOTE: for European speeds, add the accessory TEC-26 control listed below.

Attachment & Power

The TXM-26C attaches with the two 3/8" tripod screws to the bottom of newer flat-base model cameras. For older pillar-base models, a winding handle screw helps to stabilize the camera. Two posts facing the camera body give extra sideways mechanical support. New 3/8" and 1/4" tripod threads with anti-swiveling slots are provided, to suit tripods and handgrips.
The TXM-26C runs on 12.6 volts DC, through an industry-standard XLR 4-pin connector. A power socket accommodates either model of magazine take-up motor, MM or WM. 48 FPS and up may require a freshly charged battery (13.8 to 14.8 volts) for reliable running. Uses about 1 to 2 amps of current.
The TXM-26C is priced at $595.
Takeup Motor Cable for MM motor: TXM-26 to MM cable is priced at $39.
Recommended Accessories: Battery Belt. AC Power Supply.
