Jeff Rowland Model 1 [Expired]

NOTE:  This amp is also for sale locally and I reserve the right to end this auction at any time

I bought this amp in 2008 and it sat unused for 6 of the past 9 years.  100% functional and in aesthetically great shape.  Silver faceplate has only the most minor, barely visible scuffs and no scratches.  This particular Model 1 (S/N 1050) does NOT have the bridging switch to use it as a monoblock.  I love this amp so much that I bought 2 more used ones (with bridging switches) brought them to Jeff Rowland who went through them and performed a"Series II" upgrade to them ($450 each) for me.  I am now enjoying this pair of Model 1's.  But... this (my original) Model 1 certainly performs very well on its own as a standalone stereo amp.  I live in Colorado a few hours from where Jeff Rowland Design is located.  If a buyer wanted to have THIS amp upgraded I would consider doing that for the $450 that Jeff charges plus $100 for my travel time.  

I will ship insured (of course) anywhere in the U.S. Buyer to pay actual shipping costs to their zip code.  2% added for paypal transactions.
