|Studer A810 FULL MONTY comprehensive overhaul kit


$995.00 AUD

A810 FULL MONTY complete service overhaul kits for ALL Studer A810 reel to reel tape recorders.  Now includes tension dampers and guide rollers kits within the mechanical sub kit. Indeed everything you are likely to need for a full restoration and renewal.

Over the years customers have asked for a full kit instead of ordering individual sub kits. They also have tended to ask advice on what they should do to fully overhaul and restore their tape machines. So this is what I recommend and if a machine comes into our workshop THIS FULL SET OF KITS is what we fit. It takes into account the most likely components mechanically and electrically that may have degraded over the many years due to sitting idle or being over-worked. So, if you want to  service, restore or overhaul your machine as completely as you can, this is what I recommend.  

THE FULL MONTY.  A set of applicable sub kits typically containing:

  • Capacitor and Trimmer replacement kit.  All polar electrolytic, tantalum, non polar motor and suppression capacitors  and any open type trimmer potentiometers. A recap for all boards including audio, metering, sync, mono-stereo switch. Does not include time code option. 

  • Motor overhaul kit for 3 motors including appropriate lubricant.  New SKF bearings, circlips and lubricant/s for all three motors. 

  • Pinch Roller kit. - pinch roller with appropriate low friction PTFE washers and metal shims

  • Brake drum linings - 1 pair for both reel turntables

  • Globes kit  - 2x VU,  

  • Tape tension damper overhaul kit includes special drag agent and seals to repack your probably non functioning dampers.

  • Separate Nagravox service sheet manuals detailing how to do it all.  Lots of pictures before / after, suggestions, updates, troubleshooting.

  • Support service to help you in case you have questions, problems, comments.

  1. Standard kit is for 4 speed or 2 & 3 speed HS (30"/sec) versions using 2 pole motor. If you have 2 or 3 speed up to a max of 15"/sec you probably have a 4 pole motor - request option 4.3uf cap which goes with the 4-pole capstan motor part no. 1.021.366.81. 
  2. Standard  is for the later rectangular battery - please specify if yours takes the older  long cylindrical battery - we have both available - see separate listings for pics etc There is no extra charge for the older battery type - you just need to say so - preferably using direct email communication.
  3.  Time code associated boards are not included in this upgrade / service as they are seldom applicable or used these days. We can on request include the few extra capacitors at a nominal fee. Please contact us directly to discuss and advise.
