SRPP Signal Output Capacitors
Hi guys

Am I right to conclude that if the output capacitor say in an SRPP circuit fails on short, I would end up with all the high anode DC voltage on the output port with the consequence of blowing up anything which is connected with this output ?

Looking forward for your feedback

Yes, you are right. If this worries you you could add protection diodes (e.g. a pair of zeners), but there is a risk of some distortion. You could use mains-rated caps (X or Y), as these are guaranteed not to fail short circuit.
