Supro Thunder Bolt Restore
This great old Supro came into the shop in pretty good shape. The chassis was covered in duct-tape and there was only a loud hum on the output. First thing was to remove the duct-tape and clean up the chassis.
After the chassis clean up, we replaced the coupling caps and power cord. The original RCA tubes were still in great shape and did not need to be replaced.
Gotta love the grill cloth and covering. This amp sounds really sweet cranked full out and the 15" speaker makes for a huge sound.
