The DS7R Controller:- Full circle display with momentary & lift to lock paddle direction switch & can be remotely controlled by computer etc.
This controller was original a SDX version for a 747 rotator, I replaced the original PCB with my upgraded DS7R PCB.
The front panel:- Has full circle direction display, Single Left/Right direction switch (with lift to lock action), Standard power switch.
The back panel:- 6 pin Cinch socket & cover plate, Fused IEC 240v socket, Meter calibration POT & earth bolt.
On the inside: - Install the upgraded DS7R PCB, LED illumination display with it's power supply on the DS7R PCB, The original SRX multi voltage output transformer was used, Calibrated & aligned to the 507 rotator.

The 507 Rotator: - A 502 was upgraded with a 24v DC motor & 4 gears were changed for a lower gear ratio.
Disassembled to the last nut, bolt & screw, then cleaned & check all parts for damage.
Repaired & upgraded the sub chassis, Made up a new motor plate, Replace the original 100v AC motor with a 24v DC version (from an Yaesu G-1000), Replaced & re-wired limit switches also  installed the reverse direction diodes, Refurbished the 600 ohm POT.
All the housings & mast clamps have been Glass Bead Blasted by IMPACT GLASS BEAD follow by etch primer & then sprayed in Pewter Epoxy Enamel paint. The stainless steel hardware was cleaned in a special solution. Replaced the control cable socket with a 5pin LTW socket on a S/S cover plate, Supplied with New 5pin LTW plug.
The gear assembly upgrades:- Gear No 1,2 & 3 were replaced with new gears that are used in a 1103 rotator, I also upgraded the No4 gear with a lower ratio, all these gearing  upgrades gives a lower gear ratio for the DC motor, which has increase the brake torque. Installed a brass support strap under No3 gear to remove the weight of the heaver gears above No.1 gear (this lets it spin freely).
The gears were aligned & shimmed in their sub chassis then installed into the refurbished housing with the new bearing & new grease through out.
Re-aligned & calibrated with the DS7R controller.
240vAC. 24 month warranty.
