  •  Audio Research  Anniversary Preamplifier is an amazing product with its stock Sovtek 6H30N-EB tubes.  Replacing these with NOS Russian Military Grade Refklecktor Super Tubes makes it awesome.  Replacing the dual triodes in the power supply and the main unit gives this the mid-bass and low end of the best.  I have 10 of these in the two units 2 in the power supply and 8 in the main unit.  The good news is these have less than 100 hours on them.  The preamp has been in the box since March 2016 unused.  I am now forced to down size the system and this is a big piece of equipment with two chassis..
  • The original tubes are also included and have approximately 1,000 hours on them.  
  • The umbilical between the units is 48" and will allow for a side by side placement or and over under placement.  
  • I have rated it an 8 because of it being seven years old.  Not because it has and damage to the unit.  The plexiglass tops have some surface scratches but nothing of significance.  
  • Buyer will pay PayPal fee.  Please contact seller for payment options.  PayPal will cost you $300+ a certified  bank check and priority mail is maybe $35.00.
