<font color='#000000'>I have an Audionics BT-2 preamp (1979 vintage) that needs some work. I got no response from Fosgate-Audionics when I emailed them for help. Does anyone know where I can get a schematic and/or parts list for this unit? I believe this piece of equipment is worth saving since it compares well to brand new units selling at $300 to $400.</font>
