[Boatanchors] Vector board or glass board source needed

[John King]

I need to find a source for glass board or vector board to mount electrolytic caps on. I need a number of the boards.
I have searched Antique Electronic supply, Radio Daze, Amazon, Parts Express  and others to no avail. Ebay has copper plated board but I prefer NON clad board..
If anyone knows of a supply where I can purchase the needed board, please advise. Thanks and 73, John, K5PGW
