Re: Tek 475A transformer replacement

Jim Hall

Many thanks to those who posted useful advise for my search for a pin extractor for the power transformer replacement in a Tek 475A. I had previously purchased a set of extractors on eBay, but had not used enough pressure to free the pins. With the help of a hammer and the correct size extractor, the pins were freed; now to the task of complete reassembly of the scope. I am repairing several 400-series Tek scopes for donation to the Physics Departments at small colleges, since most physics and EE graduates at these colleges have no exposure to use of a scope - a must for many industrial jobs.
