I've got some tube thinning to do. I've got 4 Tungsol 6x4 types, 2 x Matsushita 12FQ7 and a Sylvania 12FQ7 all will test excellent to new. The 12FQ7's will work in the center position of a Tutay modded Minimax pre, and supposedly his favorite tube type for that position.
I believe I have these all priced lower than Ebay, or anywhere else.
Please add $3 shipping per tube. If you want more than 1 tube I can combine shipping.
Paypal only please and I'll pay fees.
1. Tungsol 6X4W - big 'D' getter, shorter black and silver plates, per box sections test 900/900, mid '50's vintage - $8.50
2. Tungsol 6X4, tall black plates, angled square getter, 3 hole plates, tests 900/890, mid '50's vintage, printing is gone save for the etched '6X4' - $8.50
3. Tungsol 6X4, identical to tube 2 above, test results printed on tube and appear to be 111/110 (different tester obviously) - $8.50
4. Tungsol 6X4, tall black plates with 2 holes each, small square getter - $6.50
5. Sylvania 12FQ7, tall gray box plates, halo getter, looks like it may have copper support rods. Tube looks really good but is vintage. $13
6. and 7. - 2 identical Matsushita 12FQ7, made in Japan, short gray plates, small halo getter, copper rods, printing is excellent. I believe I purchased these as a matched pair, not that it matters - $14 each
Here's the 12FQ7's
Tungsol 6X4W (tube 1)
Tungsol 6X4 (tubes 2 and 3 above)
