Redone from scratch, a new product from us at TubeSound. A new manual package for the Hickok 530, 530B, and 510X tube testers. Includes schematics and ballast setup chart. The product covers all three models (530/530B/510X).

Benefits include: all instructional text being newly transcribed into computer by hand; factory text errors & grammatical errors corrected; factory addendums integrated into the text; and page layouts enhanced for much improved readability. The readability and presentation of this product is “Light Years” better than the original document!

The price is VERY reasonable, and can be purchased on our eBay storefront. Click HERE.
