MEXICOWANDERER, if you're happy with your homemade surge protector that’s great. But I'm no electronic genius, can’t build my own and if I did it might not work right when it’s needed plus based on the hundreds of testimonials on this forum about how well Progressive Industries has protected them from multiple power problems I’m happy with the Progressive Industries’ 30 amp EMS I purchased over nine years ago.
Good luck with yours.

As Mex stated earlier, the Progressive and similar others are COMPLETELY different animals.
Many years ago I had a very complex amateur repeater at a friends house on a hill in LA. I built the TTL control system (22 logic & audio cards) as well as the +5, +-15v supply that ran the entire system. It was protected by a ring of GE MOV's (un-fused, wouldn't have it any other way) on both the AC In, as well as the various outputs.
The 65' tower blew down in an 80mph windstorm and dropped it across the 12kv feeder to the neighborhood. There was enough energy that the rotor controller sitting on a metal shelf welded itself to the top, and the outline of the shelf laser cut the rug it was sitting on perfectly. The 19" rack housing all the electronics etched out the carpet all the way through to the concrete as well. All electronics, including the mighty IBM 20A supply, and everything it fed were trashed. The only things that survived was my GE MOV'd power supply, and anything tied to it. How the house didn't catch fire I don't know.. That event is all the testimonial for GE MOV's I'll ever need.
