Vintage Sterling tube tester in nice cosmetic condition. It is meant to test the early 1920's tubes. I did a quick test on a O1A and verified that the filament control and meter works fine, but the emission test does not. The emission side meter works, though, so this tester can be repaired without changing the original appearance. A great display piece, or it can be repaired to test those old tubes in your junk box. Buyer pays by Paypal in 3 days of end if auction and I will ship priority mail to the 50 states in 3 days of cleared payment. International sales only through ebay's global shipping services.
