j/k'ing, dont no one get upset
seriously, it is possible to do this. it was actually amazingly easy. the gp11 preamp (front) is its own section, and is tied to the mark IV power amp (back) with a simple cable. i pulled it out, and then installed iot in my dr.bass 1260 airhead cab. it did require the addition of rear rack rails (which mark at drbass provided for me along with instructions) to support the power amp section. but it ended up working out real nice.
the problem i encountered was that the enclosure that it came out of must have had some shielding of some sort, b/c it will feed back if i set the bass agianst the cab. also, i have to be carefull plugging the power cord into the amp, b/c now the back panel is more flexible. there was a wood block in the trace that kept it from moving. it was also amazingly light (about 5-7 lbs total).
i will get some pictures of before during and after posted for any who are interested.
later.
