Bob is a retired Tek engineer who refurbishes and sells scopes for spending money. He also repairs scopes at remarkably good prices. A typical deal will be a 60 MHz transistorized Tek scope for about $125. Anyone who attends hamfests in the southeast will recognize Bob as "Mr Scope."
Mr. Kidd is a retired Tek engineer who sells old Tektronix manuals:
For example, a 465 manual is $35. Also available, for $20, is Stan Griffith's "Oscilloscopes: Selecting and Restoring a Classic"... As reviewed by Wes:
"I bought that one through Tucker Electronics and it is one good book for anyone who has an old Tek scope. It details how to troubleshoot them, where to find parts and most of all, it rates them as to their serviceability in today's electronics. It also covers the MANY plug-in's out there. I had no Idea how Many was there! Like a strain gauge pulg-in?? Good book and worth the money (as I own 4 old Tek scopes and love each of them dearly ;-)"
And here's a something from Stan Griffiths, the author himself:
[in response to a plea from an owner of a dead 454 scope]
You may recognize my name as the author of "OSCILLOSCOPES--Selecting and Restoring a Classic". I love old Tektronix scopes and I want to see yours run again. I own 454 S/N B010100 (the first one!) which I bought in a local estate sale. It was the estate of one of the design engineers who worked on the project. I guess you don't have to be dead to have an estate sale since he was there personally to sell me the instrument!

Ed specializes in good quality second hand service manuals for Tek and HP. I find that a fax to him that includes a fax back number gets the best results since he has a printed request in his hand that he can check out and respond to.
Any time you are buying Tek manuals you should make sure the parts list shows serial numbers up close to yours. HP manuals should be bought by the serial prefix number (that is the number before the "A" in the serial number; make sure to get a manual that covers your serial prefix or higher. Later manuals USUALLY cover earlier models as well, but not always. The serial prefix covered by an HP manual is shown on th title page.
So fax Ed your list of model numbers with the serial prefix of each unit. I usually specify "model HPxxxx, serial prefix yyyy or higher."
Price for an average manual is $15 + postage.

[Older Tektronix 'scope stuff/plugins/manuals]
If he doesn't have what you are looking for, he will know who to point you to here in the land of Tektronix.
Most older manuals are available as fische only. The paper versions are sky high if they're available. I paid $7 for a 561A manual, and $5 and $10 for the amp and timebase plug-in manuals. Newer scope manuals are about $25 on fische, and in excess of $100 for the paper version. I was able to find a surplus fische reader at the SW Bell surplus store for $10, so it's not to bad.
HP is much better when it comes to pricing on their paper manuals :-(
The source of the OEM Tek scope air filters is alive and well.

Sams PhotoFact folders:
VCR manuals(Sams or Originals) are $15.00/each. Please Call for other manuals.
This source carries previously owned schematics for VCR, TV, AUDIO and some test equipment. Being previously owned they are able to resell them for a fraction of the cost of new. Coupled with this is the fact that they have a wide selection from many manufactures. They carry SAMS PHOTOFACTS and original manufactures service literature. I have personally purchased many manuals from this source. Initially I was concerned that they are used but I must say that this has not been a problem. Never has a single page been missing and otherwise in almost like new condition.
In the event that they don't have the exact schematic for a specific model the owners have cross reference manuals which they use in an effort to locate possible 'look-a-like' chassis for which they might have a manual. I am told that they have many...many filing cabinets full of manuals.
Payment is generally expected in advance until a good working relationship is established. All manuals are shipped first class for $1.50 and they get them out fast.
Before you send off for any schematic, it is highly recommended that you:
Some problems can be fixed without one and in other cases, a schematic will not help to begin with. Most schematics will cost over US$35 and, as a rule, are NOT returnable!
