Complete with factory boxes. Cyber 845 Mono Blocks 24W per channel of 845 Grunt. Originally purchased from Osborn Audio the Australian distributer so these have the factory 240 volt transformers (no transformer hum from the wrong voltage). Lovely organic powerful sound. Capable of running a wide variety of speakers with 4 and 8 ohm taps on the amps. Easy to bias with factory bias jack provided. Only selling because I have upgraded my 845 amps to Line Magnetic monos using a 300b as a driver. TBH the Cybers are pretty close for a lot less money. In excellent condition and working perfectly. Get on the net if you want to read some reviews, everyone praises them. Thanks for looking
