Joachim: I read your TSB board website page with interest, thank you for the excellent explanation!
I have a customer synth here where a previous tech decided to replace all the 0.33 uF tantalum capacitors with electrolytics. It is my understanding that tantalums charge and discharge more quickly than their electrolytic counterparts.
Could you please elaborate on what you would expect to happen in the circuit with velocity timing when these tantalums get replaced with electrolytics?
