I cut my teeth on this one. My Dad has had one since 1968 and I grew up listening to a Dual 1019 playing through it to EV triaxes. When I was old enough, I "interited" another one that was in the family and I used it daily until the AV craze hit in the late 90's and I just had to have a surround receiver.
I really loved the sound of the 400's amp. It was super smooth with plenty of bass and a decent amount of power. These are keepers...enjoy your new toy
.
I still have some spare output tubes if anyone needs them. Make me a reasonable offer through a PM and they are yours...
