Vic, you and your AC30's! Hah Hah, I'm loving the one I brought from you... still plan to work through the Trem circuit at some point, it should sound better than it does and for now, like you, I've pulled the valves.
I'm actually sitting across from my copy of Stephen Grosvernors book "A Service Engineer's Guide to the Vox AC30 Valve Amplifier", Hah Hah.
I may be doing an order this week or next with Tubes & More, who sell both the Vox Logo's and Grill Cloth if you want to get in on it, this time I'll prob ship Airmail, so will take 4-6 weeks.... it is expensive though if you want the brown cloth, $74.95 a yard and the shipping is going to be something as well.
Alternatively you might be able to sell on the chassis and go all in and buy a new one from North Coast Music :

Happy restoration!
Cheers
