The schematics of the HP10638A are on TVB's website:

Found this in the TN archive from Mar 2010:     (it seems that back
then there was indeed an alternative)

Now my hp 5061a opt04  03  work good , all fixed .
I am searching a copy of manual hp 10638a degausser , I would like to
build one .
searching on past message I found a message of a schematics called
degusser.zip
any info ?
regards Alfredo
I did the replacement degausser you found the zip file for. I use it for
my 5061s quite successfully.
It fairly closely duplicates the time and current profiles used by the
original.
If you have any questions, please ask.
