why not build an SP1# kit to match?
that said where did you find a Cary SLP94 that's a killer preamp for the era (no remote though). i used to have one and still miss it. they are rare as well.
better than the offerings from Tubes4hifi IMO. I have Tubes4hifi MK4 mono's (ST-70 in 2 chassis) they are little bit noisy on my 105db horns couldn't use them unfortunately.
