This is the dbx 1066, not as expensive as some compressors but a good creative tool. A walk through guide on one way to service and/or mod this piece of kit.  Two capacitors that looked a little worse for wear, were replaced and the optional output transformers (Jensen JT-123-DBX) were installed, as well as replacing some Insulation Displacement Connector's (IDC's). This item was sold to a customer in Spain.
