It is a nice clean tester, but needs a tune up to work properly. I measured emission when testing a tube, but the line adjustment will not adjust as it should. I’m listing it as I don’t have time to investigate. The roll chart works well and has the early double digit tube numbers shown. The instructions are in the lid. The bias control knob is not correct for this tester. The tester measures roughly 17 by 11 by 7 inches in size, is grey, and may have been repainted. This is a high quality tester that should be restored and put to use. Shipping weight is 30 pounds. Please see my other auctions for more radio items and tubes.
