Vivitar 283 Thyristor Flash and SB-4 AC Adapter in Original Boxes & Tested!

Description

Selling a Vivitar 283 Thyristor flash and its SB-4 power. Both items appear in VG to excellent condition and each was wrapped in original plastic in original boxes.  The 283 includes Vivitar booklets. I did plug the SB-4 into the 283 flash and it tested/worked well.
Thanks for looking + enjoy!
