Thanks! good to see you as well.

Very cool, I wish I could build my own gear. I guess some tubes might be a bit harder to get now? A few of my guitar gearhead buds are concerned.

Yeah, some are going away, but they are being replaced by others.  Technology now is such that there are tubes now with the same pin outs and voltages which will accomplish the same thing, just a different manufacturer.  I'd be really surprised if tubes for Marshall will ever be unavailable, there's way too much demand.  Now, some other obscure off-brand stuff from long ago might not be able to get tubes, but again, it's a demand issue.
