AUDIO RESEARCH SP 10 - TWO CHASSIS TUBE PREAMPLIFIER

Here is a superb full featured all-tube preamp from Audio
Research - featuring no less than 12 tubes in the preamp stage and 3 in the
power supply.The physical condition of this unit is exemplary. This is a one
owner set lovingly taken care of since 1989. New set of tubes inserted back in
2012 and checked out by Audio Research. Everything working as it should.
Minimally used since then in a climate controlled environment. No smoking. No
pets. All is original and unmodified.

Please note there never was a Mk II by the factory as most
audiophiles think. Check the ARCDB website below which explains it all. This
has practically almost all revisions from the factory up to the year of
purchase. This I believe takes it all the way to Revision 6 I believe.

The cosmetic condition of both pieces is super-clean, flawless,
 as reflected in all the photos.

The Audio Research SP-10 is one of the best sounding
preamplifiers of all time and is a true classic.  Very hard to find in
this one-owner only condition. New buyer will be absolutely delighted and
ecstatic.

Actual insured shipping (FedEx) to be paid by purchaser to PayPal-verified
CONUS addresses only. Note that the dimensions and weight listed above are for
each of the two boxes, so the calculation of shipping costs should be
doubled.  A third box containing all tubes will be included and all
labeled for safety of shipping. I can also ship to a customer with a FEDEX or
UPS account.

Do not have original boxes but will be expertly packed – 2 boxes
for the main units – 1 box for the tubes properly labeled.
