Default FS: 2 Red He-Ne Tubes -Cheap- Need Gone ASAP

For sale I have 2 Red He-Ne tubes for $22 shipped (or $12 shipped for one). These are perfect for your first gas laser! You just need a power supply.
If I recall correctly, the tubes are 0.5mW at 1500V 5ma (I am not totally sure on that so if someone could confirm this)

I need to sell these ASAP because I need to order a new portable hard-drive for school because mine died and I lost lots of important stuff

I think you will need more then 3mA to power this, but I could be wrong

It's just an ad for a chinese company, probably spam.

The people at Everbuy seem to think that this is a good marketing strategy. They keep coming back just to post a link. We play "Whack-a-Mole" with them a lot

Peace,

Shoot, "Whack-a-Mole", that reminded me that I forgot to select which of the hot peppers I am going to use for the Guacamole for the carne asada at home!! So who likes hot/spicy food? LOL!!!

Thanks for the reminder Dave!!
