This should answer most of your questions:

I've read quite a bit on tangent's site, but there are so many options on mouser I'd like for someone to just point me to the proper ones for this project.

In order to DIY you must, at some point, do some of it yourself.

Don't see anymore of the cisco ps on ebay. Best price I can find is like 15 used shipped in the US. Anyone know a cheaper place to buy?

I think I'll go with vacuumtube.net for the tubes they have them in stock for $4+shipping, so if you know a cheaper place for tubes let me know that as well.

Try Ebay UK, you'll pay a few pounds in shipping but there are some good deals. I bought 3 for 1.50 each.

It looks like all you guys bought every 19J6 tube. radiodaze and vacuumtube.net are out of stock.
I've got every other part on order, just short tubes. May have to pick them up off ebay, kinda pricey and I don't see sockets either.

Anyone have a 4 tubes+sockets sitting around they would like to get rid of, I can paypal you a a reasonable offer.

Not sure about used, but for a new PS I paid the same ~$14 shipped which was on par with what others have paid. For tubes it's a little more difficult, but just search tubes on google and probably 10+ tube vendors will appear. I ended up emailing a bunch of them and many said they had stock of them (~4-7/ea.). I haven't found any on eBay minus the occastional one.

Can someone give me some suggestions for troubleshooting?

My SSMH has developed a bit of hiss. Sort of like when you put on an LP before the music plays as the needle picks the scratches, debris etc.

Could it just be the tubes? Or should I open it up and take a close look at the mess of wires inside?

Logistic, not sure if it does change with moving the tubes. It seems to come and go. It stays for most of the time though but it isn't just a constant hiss, it fluctuates a little bit. (Sort of like I described previously with the similarity to a record needle)

I just finished my amp, and I am blown away by it. Needless to say I'll be sticking to tubes for the foreseeable future.

Thanks to pmillett and everyone who's posts helped me out.

I was worried about his/hum but there is none as far as I can tell. It has a pitch black background. I used 470uf caps all around and am using a 1.25A power supply from a Cisco device.

Quick question: Tubes for these are getting rare, and I have two sets. One set is well matched but the other set is not. They are both GE brand but have different internal designs. One is also much brighter than the other. How audible are differences in tube design?
