Spare parts.
 

I've got a Hartke HA3500 Head for my bass amp. It was rack mounted originally and is missing the cabinet screws and also because I haven't had them replaced it's been sliding about in transit and the screw for the Master volume has snapped in half. They don't seem to have a website. Anyone know any good sites you can order parts from that might help?

Hartke is owned by Samson.

Here's a link to there parts division:

Samson - Accessories and Parts

And yet they don't have the HA3500 Head on there. Out of all the items they sell you think they'd have that head. Not good.
