Picked this up from AKer Kenwood Man in Philadelphia earlier in the week - it was a Barter Town deal.
This thing is one MF'ing monster!
Witness-
105 pounds (I used a block and tackle to hoist it onto the work cart)
Over 250,000 mfd of power supply caps
32 output transistors
350 watts per channel into 8 ohms
3 fans
3 big honking meters
Should suffice for some serious listening and perhaps a little welding on the side.
The bad-
The power switch was snapped off (easy fix with a stubby bat handle minitoggle switch).
Two of the meters are missing the glass (minor)
One meter is missing the needle (a bit of a challenge)
Three meter bulbs out (yawn, 24v bayonet incandescants)
And most critically - one channel doesn't work - now that's going be a PITA to track down. I'm guessing toasted output transistors. I've read that I can use some on semis to replace them, to be determined.
Getting at the transistors is going to be fun - looks like it requires the removal of both side panels and then it should splay out - we'll see soon enough.
Once I get this operational I have a few mods in mind. There are a few tantalums that will probably get replaced with audio grade electrolytics, it loos like the driver PCB has some opamps so I may update those, the RCA jacks and speaker terminals look a little wimpy so they'll get upgraded.
Stay tuned, this one's going to be a project - at least the manufacturer is still in business so I may be able to get a service manual.
