Jon,

I applaud you for all the help you give the readers of this board,and your surge protector is a nice contribution. I feel that everyone should use surge protection on their equipment, along with EMI/RFI filtering.

I know exactly what you are talking about with blowing up light bulbs during testing. Twenty years ago I built a surge generator that charged a 50uf cap to 4kv then discharged it into the device under test. 100w bulbs and MOV's went all over the room during the first tests.

I hope that readers will use common-mode chokes after your surge protector, because they do make a big improvement in sound. On the input of the power transformer and after the doide bridge are the best places to put them. I have used them in pre-amps, power amps, CD players, and FM tuners and there is not one case where they did not make a large improvement in sound quality. After hearing this kind of improvment I wanted everyone to use them.

This whole string started when a reader posted that he heard an improvement when using a very low inductance one in your supressor design. I can believe that. We are all looking to improve things thats why we are in the "tweeks" section of this board.

I felt that your responce to him would stop him or others from trying C-M chokes in their audio systems, so I had to reply. I want people to find out about the big improvement C-M chokes can make in their systems and not be afraid to use them.

Bottom line, use your protector AND common mode chokes and have the best of both worlds, surge suppression and EMI/RFI filtering.
