Not a ralph amp but i have a couple of johny amps laying around. Johny amps were made by john walton who is credited with starting the first cable company in the united states. He started in the blue mountains of pa. At the time he was the largest seller of RCA tvs. He didnt get any reception where he sold them and got tired of taking people to the top of the mountain to show them the tvs. So he erected a antenna at the top of the mountain and ran cable down. He only charged like 1.50 a month and if you left him install the amp in your house you got free service. Service electric cable is what its called now. Actually pretty cool to look at them. he built them from scratch and they did a pretty good job. He did a really nice job of building them to. I will see if i can get my son to snap some pictures and post them if you want.
