Thanks Al I just bought a new pair to try. Much easier to find then 4e27
Things worth mentioning for anyone like me that might find this thread. I hope I am correct in saying.
Buying used tt filament on eBay is risky because the filaments go brittle when used.
The tubes with yellow like paint/epoxy) on the bottom are possibly risky if not all likely to loose there vacuum. And should be avoided.
The plates need to get red to operate correctly long term so plate cooling needs to be well considered.
As for switch mode power supples... have seen it done with 808 on valves world Japanese website which has inspired me for years to try build with weird funky but cheap to buy tubes. But those guys are supa cool for building to order from customers for all sorts of funky tubes but I suspect novelty and price constraints may effect sound quality standards.
hmm sofar that's it. I will keep trying.
