/* Finding The Right Parts */
The Polyester type capacitors used in the 6128+ are also very difficult to find as they haven't been produced in that form for many years.
Polyester based MKS capacitors should be used for these(The red box type which can be seen in the picture below), ceramic or standard multi-layer capacitors are not advised. They may work, but
this is far from guaranteed. As MKS capacitors are very rigid, make sure that the pin distances are correct for the PCB footprint.
For the ceramic capacitors, any standard multilayer non-poled capacitor will do.
