My old GE tube substitution manual grew legs and lost itself to a un-responsible borrower awhile back. I found a great tube-sub manual online for free download if anyone needs one. This manual is the 1953 Sylvania Tube Sub manual, and covers it ALL!
This manual gives all info to sub tubes,( all types) how-to & all info to do socket changes if wanted, wiring changes,adding resistors if necessary, and all etc! It is free for download in pdf files.
For radio type tubes, just download and print pages #1 thru 24 covers all radio tube data. Pgs 26- 42 covers all TV tube data.
For both newbies & veteran-tube techs as well, this manual will come in very-handy to all, especially if you dont already have one !!! You can find it here:
