Circuit board TSZ-unit - new.

Please note, this only fits in the transistor units with cooling fins on top. Model: BUX37 (most commonly used model).

The electrical components of the original TSZ-units are subject to age.

This can cause values ​​to go out of tolerance or the printed circuit board to be damaged, even if it has never been used...

These things do not cause a direct defect but for example an incorrect spark angle in the ignition.

Cold start problems, low power or incorrect ignition timing can occur.

In these cases, the circuit board must be replaced.

This also means that new TSZ-units (NOS) are no guarantee for a qualitative repair!

This new generation of circuit boards is a redeveloped product in which the most modern components of a high technological level are used. All these components are more resistant to thermal influences.
