October 3, 2018 Update
We have scanned and uploaded the RPR for 151- transistors.
This is great news for Tektronix collectors and restorers. We have worked with Tektronix to obtain a release for the Replacement Parts Registry (RPR). Our RPR is from 1986 and is quite extensive.
The RPR is a reverse lookup of part numbers and what instruments they were used in. Other instruments are typically the only source for Tek-made components and we have scanned the most needed categories of 120- (Transformers), 154- (Vacuum Tubes, i.e. CRTs), and 155- (Tek-Made ICs). Here is a sample from the RPR for a 154-0478-02 P7 CRT showing the instruments it was used in.
