While looking for tubes on Alibaba..

[Kapo_Polenton]

I found this... all heil the clone of another clone ..Friedman clone ( I think based on the description maybe?) Some chinese tubes available for bulk buy still which is why I am less worried. Alibaba has contacts that neither of us have no doubt.
