I shall never do such a sacrilege. Mechanical vibrator is performing very well and I have another one to replace in case of catastrophic failure. I read some articles in the web who says that a properly designed trafo and with wright value of buffer capacitor, a vibrator can perform over 30 years with no fault.
A clean contact may have some milliohms of resistance whilst a bjt loss a volt across its emiter collector joint, much higher than a vibrator. So I wonder which advantage are you talking about.
