Question about GE 6KD6 tubes

[ray911]

Hello guys,
I'm new here and thank you for this forum. I have an new old stock of GE 6KD6 well preserved (over 50 units I think). I would like to ask you what's the best way to sell like forums, websites, ...etc. I visually inspected them and they look perfect and shiny.

1. Websites, forums or customers who buy it?

2. Do I have to test them first and won't that affect its price?

3. Is it better to sell it individually or whole?


Sincerely,
Ray

Testing them will not degrade the tube. It will certainly help with price.

Ebay is a good place to sell tubes like this. I'd sell them individually. This is a TV tube, but hobbiests like to use it as a power tube in audio amplifiers.
