Vintage Denon PMA-830 integrated amplifier, in excellent working condition, there are some marks and blemish in the left back coner please check photos with note, this amp can play class A 15wpc at 8ohm, and class B 90wpc at 4 ohm.

 

 

One of the best amp integrated amp was manufactured about in 1978, really nice sound stage, heavy base, refine midrange and sweet treb to my listening experiment.

 

 

Local buyers welcome to have a listen pre-purchase, also happy send video clip recorded for inspection and listeninng demo. This amp is quite heavy state at 17kg not include package, this amp can be packed properly and safe for travel interstate and oversea.

 

 

Please note: This amp is 100V Japan domestic, will need a step down transformer to be used in Australia.
