Precision Tube Tester 620 Operating Manual



For sale is reprint Precision Apparatus Company Tube Tester model 620 Manual. 18 pages long, Manual comes with Part List and Circuit Diagram. 

If you purchased one of those testers from Ebay and it did not come with Manual. Looks like Manual was typed on typewriter and Mimeorgraphed as it was printed one sided. No fancy Typeface Font but manual is clear and readable. I also have 92 page tube test data book in my ebay store.
