I sell new 3-500 Graphite at $230 a pair and 572B's at $125 a pair
shipped in the USA lower 48......plus shipping elsewhere.
They are from the best Chinese factories and carry a full 1yr no
questions warranty. I have been using and selling for years with
excellent results and reliability.
Just about all 572B's except Cetron will require a bias mod in the
2100B....real simple and parts available at RatShack and similar places.
The other tubes have higher gain and the 2100 does not provide enough
cut-off bias to preclude a TPTG oscillator. I'll include the mod info.
For overseas customers I will even pretest the tubes.
