Tektronix maintains service centers worldwide. These centers provide calibration
and repair services for Tektronix instruments. They can be contacted through
your Tektronix field office or representative. You can also find service and
support information at:

Not all service centers are equipped to repair or calibrate all instruments; please
be prepared to provide the instrument model and serial number when calling for
assistance.
Replacement parts are available through the local Tektronix field office or
representative. However, many common electric 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
4. Modification or Option Number (if applicable)
The instrument consists of etched circuit boards. All of the circuit boards are
designed as assemblies. Each assembly has as alphanumeric designation (A1
through A4). These assemblies are listed in the Replaceable Mechanical Parts list
of this manual.
NOTE
. A 2% RMA flux content solder is recommended for making repairs in this
instrument. Cleaning of rosin residue is not recommended. Most cleaning
solvents tend to reactivate the rosin and spread it under components where it
may cause corrosion under humid conditions. The rosin residue, if left alone,
does not exhibit these corrosive properties.
