guys! I just got back from wellaudiolab. I bought a mullard ECC81 (12AT7) and a westinghouse 12AX7/5751 from him ($20 each). The 12AX7 was to replace the one that was spoilt. The amp is working perfectly now. No more hiss on the reverb channel. Yay.
Yah think it uses a spring reverb. There's a big box at the bottom of the amp housing the reverb. Its connected to the chassis by a couple of wires in and out. The reverb is sweet.
Can get quite overpowering though if you turn it up past 5.
Anyone can advise me on the placement of the various tubes? There are six pre-amp tubes V1 to V6.. anyone know which pre-amp tube is for what?
edit: nvm, found an excellent explanation here:

hmm yah. i just realised it after reading that link i posted.. can leave out tube v1 if not using the clean channel.
just had a chance today to clean up the amp. you won't believe the amount of dirt that's stuck on... my rag turned black. urg. Its so much cleaner now. Just realised that the reverb tank is enclosed in a nice leather bag. wow. didn't realise it before because it was hidden under all the muck.
Anyone want to try it out just give me a pm. I'll try to accomodate you. i stay in the west.

eh hiya Daniel. Anytime man. Aiyah but this weekend busy with work. Maybe next weekend. i'm keen to try out some juicy overdrive units on the amp. 
i'm keen to try out some juicy overdrive units on the amp. Yeap, the blackstone sounds very modern. It not your normal TS clone. if you are after that kind of tone, steer clear. I find the TS tones muddy though, but YMMV.
You should drop by the Blackstone Applications website though, their sound samples put things in proper perspective. They a/b the Blackstone with a TS Clone and Klon, you can hear how muddy a TS clone is.
