Does anyone know where to find a replacement for the Welch e/m vacuum =
tube? The standard vendors sell replacement tubes but they are for =
their particular setup. In the meanwhile, we are looking for a glass =
blower so we can repair the 3 broken tubes we have. But it would be =
wonderful if we could order it from a vendor instead of a custom job. =
Has anyone had any experience with replacing or repairing these tubes? =
Any help would be greatly appreciated as we are down to our last tube =
and it's getting quite dim. Thank you. Respectfully,

David Haley
