ebay tubes vs vacuumtubes.net $$$$$$$$

Just a Heads Up.

Looking at ebay prices vs vacuumtubes.net, the more desirable audio tubes are usually less cost at vacuumtubes.net

For example, three Sylvania 5751 two mica are at $140 on ebay right now & may end up at $180+. These are likely used in original boxes as test scores show just slightly under or making new tube measurement vs the usual 20-30% over minimal new tube reading for NOS. Vacuum tubes.net has Sylvania 5751 triple mica black plate in NOS for $35 each. The triple mica are more desirable tubes- the real deal. On ebay right now black triple mica Sylvania black plate are $109 to over $200 per pair USED. At times stock does run out at vacuumtubes.net, but check back a week later. I just bought two NOS NIB Sylvania 5751 triple mica black plate for $70.

Another example- Telefunken ECC801S- Usually NOS pairs on eBay are for over $200 and some are ONE tube for $209. I bought same item for $35 from vacuumtubes.net.

I think a sharp buyer could make a minimalist living or at least a luxury car payment buying from vacuumtubes.net & reselling on expensive ebay.

Bartertown here is a good source for vintage tested tubes. Don't know about flipping them, but join and you will be amazed. But you gotta be quick to buy, cause they often go in a matter of minutes.

Years of testing preamp tubes. Does not always hold true. Telefunken NOS 12AX7 always read high. Tung Sol NOS 12AX7, about 200 gm less.
