Do you mean that the relay won't click? If so, there is a notorious problem with the relay transistor going bad. http://www.audiokarma.org/forums/showthread.php?t=277328&highlight=ka-7300 I just rebuilt the power supply board on mine including new relay for around $12 in parts shipped.
I'd say get it.

Well I got it for $60.00 hope I did not pay to much.
Nice shape and yes the relay does not click.
Started to look into it and it is a PITA to get at the Protection board.
Found this from a post in D&S the second owner used for a very short time and it quit working.
He took in to a repair shop was charged 30.00 to be told there is a bad
transistor and maybe caps in the protection circuit. Sound familiar.
Just last week I got a KT-7300 for 33.00 and put it in to the rack replacing a Sansui anyway now I have a matched set.
Really do not need this Integrated but I thought I would try the pre amp
I will more than likely give it a recap and maybe add EW's mod for the offset.
Well need to get a SM for it unless anyone wants to volunteer a copy.

I disengaged the back panel from the frame so I could get at that board. Replacing the relay was the biggest pain.
There's some info here http://www.audiokarma.org/forums/showthread.php?t=283713 regarding two transistors responsible for offset; hopefully mine will be in check(45mv, 55mv) after I finish the power amp boards. The parts should be here tomorrow.
I used it as a preamp hooked connected to a Realistic STA-2000 and thought it sounded very good.
No SM, but I have the schematics from a link floating around here somewhere. If ya can't find it, PM me.
