This item is posted for sale to raise funds to help pay medical expenses for a friend, a highly respected Musician, Recording Engineer and Educator who suffered a debilitating stroke around 3 years ago. The stroke left him completely paralyzed on his left side. Recognizing and accepting that he will no longer be able to use his home studio, I have been asked to help liquidate his equipment.
SPECIFICS FOR THIS AMP:
• The "Type CSRA" Mark: This designates the Custom Shop Reverb Amplifier series. While the general catalog model is often denoted as "CSR 4", the chassis and safety compliance stickers on early/mid-90s models read Type CSRA.
• The Revision Status: By serial number 1686, this unit sits right in the sweet spot of production. The earliest Vibro-Kings (1993–1995) used an EL84 tube to drive the onboard '63-style reverb circuit, which frequently suffered from overheating and tube failure. Your mid-90s unit likely features the upgraded, much more reliable 6V6 reverb driver tube circuit.

Sonically, this amplifier is essentially a hand-wired '59 Bassman circuit paired natively with an integrated '63 outboard tube reverb unit.
