That is an excellent book. One of the most useful for the older analog scopes. I have read through this in the past, but am reviewing this yet again. I just found a nice (and very cheap) 485 and a 465 that have nice bright traces, but need some TLC in other areas. I always get something from this book. Should be required reading for any novice scope tech or hobbyist. You old pros in the group probably have this memorized. Superb information.
Thanks for reminding us about this..
