Vintage Tektronix oscilloscopes model 502A & scope cart.
FULL OF VINTAGE TUBES (27 TOTAL).
The unit turns on & then blows the main fuse.
Being sold as "for parts only" or "salvage".
I know nothing about this scope other than what is stated here.
Hoping someone can repurpose the tubes in their amp/amps.
