Revox A700 BASIC Electronic capacitor kit


$214.00 AUD

This kit should be considered the absolute minimum BASIC kit and contains the following high voltage AC capacitors and components which are easy to replace and are often faulty .

  • 2x (6.5uf 250 VAC + 1.5uf 250 VAC) Reel Motor Capacitors -  special 3 terminal dual cap (separate 1.5uf that fits on outside easily).  Fits perfectly no mods needed.

  • 1x 3.5uf 250 VAC capstan motor capacitor

  • 9x 300VAC suppression capacitors.  Absolutely essential to replace

  • 1x 0.1uf 300VAC - mains filter capacitor

  • 1x drive control system relay - this relay does a lot of work and often is the culprit of spurious problems due to suppression caps failing.


How are Nagravox kits organized and what’s the difference?

·         BASIC Kit. This is the absolute minimalist kit and supplies the most likely capacitors that have degraded - motor capacitors, suppression capacitors and associated suppression resistors.  Aluminium can power supply capacitors are included if fitted. Motor control braking relays are included if applicable.

·         ELECTRONIC capacitor and trimmer Kit. This adds all the other polar capacitors in the tape transport, PSU and audio modules and systems. All tantalum and electrolytic capacitors are replaced. Open type trimmers are replaced with closed modern cermet trimmers. On some models critical relays and some transistors are included.

·         BASIC MECHANICAL Service Kit. All replaceable motor bearings, circlips for 2 reel motors and the special lubricant for the capstan motor. A general lubricant for levers, bushes and linkages is also supplied.

·         FULL MECHANICAL Kit. Added to the basic mechanical kit, we add a special drag agent/ lubricant to service the tape tension dampers and parts to replace brake linings, tape guide roller bearings, tape counter belt/s (if applicable) and the pinch roller.

·         FULL MONTY. This is a fully optioned kit and what we would typically fit to a machine that comes into our workshop for a full overhaul / restoration. It includes the above ELECTRONIC capacitor and trimmer kit, FULL MECHANICAL kit PLUS spare bulbs, securing hardware and new RCA sockets if applicable.
