Bryston PP300

I am selling a pair of Bryston PowerPac 300 amplifiers.

The PP300 is a modular, single channel power amplifier delivering 300 watts at 8 Ohms, or 500 watts into 4 Ohms and is the modular monaural version of a Bryston 4B SST stereo amplifier.  

I purchased these units new in 2007 and have used them as subwoofer amps (although they work perfectly well as full-range amps). 

Despite their age, they work perfectly and still have 6 years of warranty left (better than most new equipment). I have the original bill of sale as well the original manual and shipping cartons. 

Features include: 

• Allows direct attachment or adjacent placement to loudspeakers
• On-wall mounting
• Easy application in any multiple driver active or passive stereo system
• Balanced or unbalanced operation at the flick of a switch
• Gold plated 5-way banana jacks, RCA and XLR connectors 
• Ground lift switch to reduce annoying hum
• Level control adjustment 
• Detachable power cord.

I paid $1300 each for them and am asking $500 each or both for $900.
