Thanks for the warning. I won't buy any 40 year old mid-fi amps from Phase Linear. Not that I was any danger of doing that.......
phasel linear 400
back in the 70's the 400 and 700 were the cheapest for the most watts. they are known to fry speakers because they didn't work well under stress. I will never buy a refurbished one. I have McIntosh now!
