Yes, and that cap is a 1000v Ceramic type, probably Philips branded.

"Next is the power supply. In the scheme I have it calls for (6) 200 uf caps @ 300v, (2) 10 uf caps @ 450v, and a 40uf cap @ 450v, I've got a picture of the insides of a SLO (from Randall Aiken's site I think) and those caps on the schematic don't seem to be there!?!?"
 
 
The power supply board has components on both sides. Since you are building a 50 watt version, just use a couple of Illinios 220µF/330v caps in series for a total of 110µF for the first capacitor section. Follow it with a 60µF/500v capacitor after the choke, then the 40uf then the two 10uf/450v caps which are located on the pc board close to the preamp tubes. A Hammond 273BX is pretty close in voltage for what you need here and has been used already with success by Jeff Stapleton in his homebrew.

"Info on these questions is GREATLY appreciated, and if anyone has any advice on the construction of this amp or corrections to the schematic I've got, I'd really appreciate the info."
 
 
There are 3 corrections to the schematic. First, the clean channel is fed from the junction of the .02 and .002/470K you mentioned above rather than AFTER the .002/470K as shown on the schematic. Second, there is a .001µF capacitor bypassing the OD Volume control which is missing on the schematic. It connects between the high side and the wiper of the pot. Third, the 100µF capacitor in the LDR switching circuit supply is actually 1000µF/16v.  
 
Just to wet your enthusiasism a bit, here is a blurry pic of my Marshall combo I SLO'd! http://www.communique.net/~jlemoine/Marshall_slo1.jpg.  
 
And yes, we have tons more info. Contact me by email or join us in the Ampage chat area any evening around 7pm central.
