I found your reply in the mail that was forwarded from the subscription

Thank you so much, this really helps. I think I'm going to go with a
bipolar electrolytic, incidentally I happend to find 10V/16µF in my
parts store, so why not. Will check if there is any effect on the audio
spectrum but I wouldn't expect a huge difference. Voltage measurements
without caps in place will also follow.

Cheers,
Joe
