This a complete reprint of the Superior Instruments Co. Model 85 Dynamic Tube Tester manual with one of the most recent tube test charts.  It's the documentation you need to use and maintain your SICO 85 tube tester.  The Model 85 is a Dynamic tube tester.  It's a very nice tester that's a step above a simple emission tester.  The Model 85's tube tests include separate plate and grid settings to make readings more representative of the tube's overall quality.  The Model 85 is a good instrument and is worthy of continued maintenance and operation.  This manual set will help you do that.  Included are the following reprint copies:

• SICO Model 85 Operating Instructions dated 1960 (12 pages)
  
• Enlarged schematic dated 1959 (1 page)
  
• Tube chart with instructions dated 2/64 (38 pages)
• Foreign tube substitution chart (1 page)
  

The manual and schematic are excellent reprints.  The tube chart is a good copy which is readily legible.  The original setup chart had marks and imperfections which have been digitally and manually cleaned up.  It is also very readable.  I've owned and refurbished several of these SICO Model 85 testers and made sure to put together the most complete and recent documentation set possible.  I'm pretty sure the 2/64 tube test setup chart is the most recent published.  This setup chart lets you test more recent audio tubes such as the EL34, EL84, 6550, 5881, 6BQ5, 7591, 6CA7, etc.
