I have these singles of each of these sitting around, so I thought I would try to find another to pair up with.
Both of these tubes test very strong, but I don't need to make a matched pair - only looking for another strong testing one of each to be reasonably close. Alternatively, I guess I could take another 3 of each to make two pairs (or a quad).
The Tesla has codes "37", "503" and "C7", and is branded Ruby E34l-CZ (but the brand does not need to match).
The Sovtek is just indicated as EL34, and has a code that appears to be "НЗВ3" (my cyrillic is not too good).
Not looking to spend a lot of cash on this, but I can pay via Paypal. I also have plenty of tubes to trade (and have some other interests if needed for a larger trade).
Shipping would be to zip 19317.
