I have a pair of these that are used and I’m unlikely to ever build a 300B PSE (seems a common theme with 300b amps??). I’ve had them sat in a cupboard for 8 years since being bought used!
I don’t post much on hi-fi forums recently but hopefully some of you will remember me from shows and a few bake-offs etc.

Current RRP is £737 delivered.
I’d like £350 + delivery or collection from surrey/hampshire border.
