Default MARANTZ PM700AV schematic/help

Hoping someone might be able to help out.
Inherited one of these units with a blown output... the unit has been previously repaired and looks like someone has swapped the original (?) STK4154 to the higher rated STK4164 ..
Wondering if anyone is aware how swap-able these units are with any other STK chips and if anyone can point me in the direction of a source of STK units?

Would like to get the amp back up and running rather than abandoning it to it's own devices in 'the shed'
All help appreciated

Brett

Thanks burnedfingers .. dropped them a line

really after a schematic now so that I can check voltages etc.. hate to get a replacement STK only to find that the fault was not a voltage fluctuation (they seem to kill STK modules very easily)

for the same reason i am hesitant to swap in the other STK module across to the 'bung' channel

Anyone know of a source or if any other marantz amp was similar enough to provide an idea??

Send Marantz a email. They may be able to help also.

Also... is there a roman numeral II after the STK number?

I used to have a link to some STK information but cannot find it.
