Tung-sol 12AX7 gold pin old issue


Hi,
do you know how much the vintage Tung-sol 12AX7 gold pins matched pairs are? where do I find them?

If you meant the reissue, I found the gold pins' sound to be somewhat 'dead'/flat in both my CAT pre and my tube amp. The regular steel pins sound is more lively/dynamic.
The extra cost of the 'gold' was a waste of dollars imo.
