How much are these tubes worth?

I recently acquired an HP Standing Wave Indicator and they had 2 tubes, but the prices vary from $16 to $130 from the sites I looked at. They are 2 ECC83/12AX7 with labels saying "Made in Western Germany" and "TELEFUNKEN". Any idea of how much these are worth would be much appreciated.

The price I quoted above was for the pair of Teles.  Look them up on ebay there are plenty for sale there.

Telefunken 12AX7 that test new are probably worth $125 and up, depending on the cosmetic condition, how closely matched the triodes are (2 triodes per tube), how much over new they test, etc.  If they test below new, the price drops rapidly.
