I have a few tubes that came with a headphone amp that I sold and I forgot about the extra tubes. And 3 other ones I forgot about...Here they are:
Sovtek 5V4C, made in Russia, at most 50 hours. $10 Mullard 12AX7, Russian reproduction, NEW. Matched Duo for $20 Svetlana 6550C, Gold Label (I think from a McIntosh amp). Test as New. $15 Shipping is calculated exact to your location and probably varies between $5.50 and $15. no fees for paypal.
