Replacement parts are available through the local Tektronix field office or
representative. However, many common electronic parts are available through
local sources. Using a local source, where possible, will eliminate shipping
delays.
Changes to Tektronix instruments are sometimes made to accommodate
improved components, as they become available, and to improve circuit
performance. Therefore, it is important to include the following information
when ordering parts:
1. Part Number
2. Instrument Type or Number
3. Serial Number
