Classe' DR9 mono blocks

Very rare vintage Classe' DR9 amplifiers designed by David Reich. I am the original owner, purchased them new over 20 years ago. I have never had a single issue with either amp. They are running in the balanced mono block mode with 400W per channel. These amps are pristine, looking like they just came out of the box. No dust is inside. Sistrum platforms shown are not included. I would prefer to sell these together. They can be converted back to stereo mode at 100W per channel. These are most likely the best condition DR9 amps on the planet. Note: the amps only accept spade lug connections for speaker cable. Will include the Silver/Gold HiFi Tuning fuses with the amps.
