   NOTE:  Sorry, no longer accepting Paypal for domestic transaction. Check or MO by mail.
May have exceptions for overseas transactions. My state, Virginia, has decided to require reporting of Paypal receipts to the IRS, resulting in the receipts being subject to federal and state tax. There used to be a $20,000  allowance to allow for hobby sellers to operate without taxing up to that amount. Now all Paypal receipts are taxed as income so I lose about 35% to taxes and can't afford that. I don't operate this site to make money, and most of what I sell is about a break even for what I have invested, but can't afford to lose money on it. Sorry for the inconvenience, but we have our greedy governor and state legislature to thank. The states of MA and VT doing the same.

Valvart 2A3 Tube (noisy)

This is a new old stock Chinese Valvart 2A3 tube that tests as new at 74, but when auditioned has some static you can hear when there is no sound input.

Should still be safe to use and will sell cheap at $9.
