Hi, same problem here: an electrical surge at home destroyed something within my SUB-20A... that I bought some... 17 years ago (in 2003, but was perfectly working before this damned spark).
Now it's only hissing and bumbing :-(
I've opened it, but no visible problem: a diagram would help to check it with an oscilloscope...
Any idea? Have you found it?
Thanks
