Elite Video BVP-4 proc amp, starting price $30 on eBay
 

I saw this a few minutes ago: http://cgi.ebay.com/23123460fd

It's "as is" because the person claims to now have any "cords" to test it with.

There is plenty of information on this site, for both usage and repair/tweaking of BVP-4 units. (Search forum.)
A new power adapter is easily found at Radio Shack.

If you have $47 to gamble, this may be a great buy. :thumb:


Disclaimer: I am not the seller, I don't know the seller, etc etc. Just an observation worth sharing.
If you buy it, and it's broken, don't come griping at me!
