Revox capstan and reel motor lubricant for all early Revox  36 series and Studer A62 reel to reel tape recorders.  

LUBE KIT - "Teresso 43"  

This kit is for  earlier capstan motors that use a separate flywheel assembly coupled to the motor both of which use sintered bronze bearings. also suitable for early reel motor lubrication and motors with sintered bronze bearings with or without a roller bearing.

This kit contains:

  •  10-12ml special Mobil modern equivalent to Teresso 43 which we call "teresso 43" in 12ml pottle.
  •  special draw needle and syringe for precise application

F    Confusion with Mobil DTE-EH  there was some confusion at some stage in the history  between G36 - A77 - B77 that Mobil DTH-EH should be used retrospectively for the 36 series motors.  Although this works fine on most machines in our experience, I have found on overhauling and fitting a new capstan shaft. the thicker lubricant may possibly cause some drag affecting speed by about 5%.  Studer / Revox did suggest that if this occurred to leave the machine running for a few hours before using.  We have not been too happy with that  vague instruction and have sourced an almost direct modern day equivalent oil with a similar viscosity 45 versus original 43.  The oil is made by Mobil and recommended as a replacement.  We now stock this oil and have called it "Teresso 43" thus acknowledging that it is an equivalent.

Capstan motors need lubricating every ~500 hours or 6 - 12 months and full clean and new bearing at ~2000 hours or 3 - 5 years. 
Do this and the motors will last a long long time. Most motors I have come across have never been serviced and the lubricating felts are dry. Luckily these old capstan motors are really robust and can be brought back to good serviceable condition. They are relatively easy to dismantle and once upgraded / serviced will run smoother with less noise. With a good clean, new bearings and a lubrication its surprising how well an old motor can run. Don't take a chance on dubious bearing sources or lubricants.  Get the full Nagravox kit for all your motors. 

General Machine Lubrication Note: The Mobil DTE EH in our kits is very suitable as a general lubricant for all moving parts on all tape machines. It is a high viscosity oil ideal for "clinging" to parts. We highly recommend that you purchase Teresso 43 and DTH-EH together.

For earlier capstan motors the correct lubricant is Mobil DTE – EH or Teresso 43 and no other lubricant should be used or mixed with them. DO NOT USE synthetic oil or Isoflex PDP65. The DTH-EH and "Teresso 43" are fully compatible and can be mixed / changed over.

CAUTION.  Dont be fooled by the hype over lubricants.  Studer, Revox and Nagra specified four types of lubricants for capstan motors. We have all of them being specialist in these marques and as originally specified. Not copies or cheap alternatives.  

FYI  these are  Mobil Teresso 43 and DTE EH for early machines from the 50's and  60's, Klueber PDB38,  PDP65 and CONSTANT GLY2100 for the later machines 60's, 70's and 80's.

or later Revox and Studer capstan motors after 1987 the correct lubricant is Isoflex PDP65 or CONSTANT GLY2100 and no other lubricant should be used or mixed with it. DO NOT USE ANY OTHER OIL!

NAGRAVOX PARTS – Important Information. 

In respect of this listing only. We don’t really want to sell parts only on ebay! Our parts are listed on ebay for the benefit of customers who, at the same time purchase a kit from us. So, unfortunately due to the onerous time consuming administration foisted onto us by ebay and the freight / postal system, we have had to instigate a ‘hidden’ in built handling charge of $30 on the low value part listed here. This is incorporated into the shipping charge (ebay system) and why it may seem exorbitantly expensive. This ‘handling charge’ can be REFUNDED in full ($30) as a discount by requesting a combined invoice for any multiple purchase of a kit plus parts. A ‘hidden’ handling charge does not apply to kits or tape media / accessories and some more expensive parts which are nett. To be clear – there is a refund of any ‘hidden’ handling charge of $30 which is passed as a discount when you request an invoice for multiple items as long as one of these is a kit.  You MUST request a ‘combined shipping’ or ‘send an invoice for combined shipping’ to enable this. Please check on your requested final invoice that I have applied the $30 discount. This message nor ‘hidden’ fee does is absent and is not applicable on those items in our store where the above message does not appear. It is also not applicable to direct dealing past customers. Our raison d’etre is to help enthusiasts fully restore their classic audio equipment to as near original performance using our carefully considered and designed kits. We don’t really wish to cater for occasional spare part sales which, to be blunt is a hassle and time consuming and which, in most cases, is unlikely to solve likely hidden or soon to surface problems on your Revox, Studer or Nagra equipment. Please give consideration and look at our kits in other listings in our store.  Thanks for your consideration and hopefully understanding and I hope we can help in restoring your machine.
