I recently picked up one of these ballasts (NOS?).

It has an octal base but I have not been able to track down anything about its use/specifications.

Can anyone on the forum be able to point me to a site where I would be able to get this information?

Thank you for your help.

Joseph

Are you sure that it isn't a 3-7? Is it metal or glass?

3H7 will regulate 0.35A with a voltage drop of 4 to 10 volts per the Amperite data sheet on my page: http://www.audio_phool.com/Techno.html (Leave out the "_")

You misspelled your website: xxx

The other link took me to a page with possible viruses on it. :shock:

Something is wrong, every time I put in the right website, it keeps changing it to the other crap.

Okay, the hard way: audio phool dot com (no spaces)
