I would have thought that a pair of 1N34 diodes would have been more costly then just picking up another 6H6 metal tube? The metal 6H6s, which are the original style, seem to be the most plentiful, followed by the GT style, I only have one radio that uses the ST style or 6H6G which is a Canadian Sparton.
