[Amps] Appraising Old Tubes

[Michael Tope]

Hi All,

I have some old tubes (Eimac 250TH's, 250T, CWL-803, CWL-861, etc) that 
I have accumulated over the years from various estates that I have helped to 
liquidate. I will probably never use them and I need the space in my shop. 
Can anyone point me in the right direction towards where I might get them
appraised, or a good venue for selling them. 

Thanks,

Mike, W4EF..........................
