I almost forgot. The original circuit applies a maximum of 0.1V peak
to the capacitor under test. This is low enough so the polarity is
not important. It will not turn on semiconductor junctions, so most
capacitors may be tested in-circuit.

Your version applies 2.5VDC to the capacitor. This means the cap
must be unsoldered from the circuit, tested, then re-soldered back
in the circuit. This takes time and risks damage to the cap and pcb.

Also, the 2.5VDC means the user must observe polarity on low-voltage
caps. This adds complexity and increases the difficulty of use.

These are significant design flaws.
