I have an OR15 and modified it to #4 spec for awhile, it's only a difference of three caps and a resistor.  I'm trying to make the changes switchable actually, I may need to post something under the amps thread. The OR15 is actually very similar to the Dark Terror when the mids are scooped.

Here's a link to the OR15 schematic: http://music-electronics-forum.com/attachments/27432d1392050035-orange-or15-sch-115v-230v.pdf

The changes from the OR15 to Jim Root Terror are as follows:

C11 and C12 are 1nF
C7 is 4.7n
R17 is 39k

Can't help you with the transistor substitutions though, sorry. I hope the schematic helps though.
