I need some 12AX7A's and I hate to buy more tubes when I have more than I'll ever use. So I'd like to trade from my excess for some NOS 12AX7A tubes. I have a quantity of American made 6AQ5, 12BA6, 12BE6, 6BE6, 12AU6, 12AU7, 12AV6 tubes, NOS in the boxes. If you don't see what you need, let me know and I'll check my stock. 73, Bill, K3PGB
