Sonic Defender
Headphoneus Supremus
It's a KR-5150--40 watts per channel on the speakers, drives my Energy RC-10 as loud as I can stand them at about 30% volume (400i are at about 45% before they get unlistenable). The lamps are all blown, so it needs to be opened up soon anyway, would be a good excuse to swap out the capacitors.
That is a sweet looking classic for sure. There are many threads about it on audiokarma so if you are interested in getting it into tip-top shape, there is no better place on the Internet that I have heard about. Tons of DIY experts, service technicians, audio nuts, you name it, they're all there.
