Description: More than just the manual for a SICO TW-11 tube tester., this is the complete bound printed documentation set for the SICO (Superior Instruments Co.) TW-11 emission tube tester. This is everything you would need to use your TW-11 tube tester. Schematic and service notes are included in case you need to fix yours. The original TW-11 and supplements won't test an EL34 (6CA7). You don't have to own a tester that won't test an EL34 and other tubes! This documentation set fixes that! Plus, if you've worked on one of these, you'll quickly find that the schematic in the manual doesn't match your as-built unit. I'm including an edited "As-Built" schematic that matches the TW-11s that I've seen in the field. Included in the documentation set is a copy of the original, 1956 roll chart (8-1/2 x 11 format). This is important to have if your TW-11's roll chart is broken or missing because the supplements don't include the tubes on the roll chart. Speaking of supplements, I'm including two, one dated November 1963 and an older one that I think is from 1958. Plus, to round out the documentation set, I'm including an edited copy of the TV-11's supplement that includes more tubes. The edits fix some chart errors in the original TV-11 supplement. Instructions for how to use the TV-11 chart with the TW-11 are included. This is as complete a documentation set for the TW-11 that you'll find. I've owned several of these and made sure to include what you would need for yours. I especially included info that would let you test some of the most important audio tubes of the modern tube era. All the copies are excellent and easy to read. As needed, gray-scale prints were used to enhance legibility -- especially of the instrument pictures. I've worked on these testers and I really think you will be better served by a more complete doc set. I don't know why I'm selling so much documentation for so little money... OK, I lied, I do know. It's because there are other sellers who give you less for about the same amount. :) Please let me know if you have any questions. Thanks
