cetoole Posted August 18, 2013 Report Posted August 18, 2013 Well, we see what happens when I build my cap isolated cables come Monday or Tuesday, before I set aside yet more "when Emily is working again" money. What is a cap isolated cable? The only thing which comes to mind are those crazy actively biased cables, which have capacitors on each end to block the dc bias.
deepak Posted August 18, 2013 Report Posted August 18, 2013 How much do you think an Extreme is worth these days? I was going to suggest to Jacob that he ask you. One and a half black and white cookies?
wink Posted August 19, 2013 Report Posted August 19, 2013 I remember that way back in the '80's. Used to have a double pole switch with centre position on the amp chassis so you could lift the earth or insert the cap in circuit. One of the options usually solved the problem

spritzer Posted August 19, 2013 Report Posted August 19, 2013 Gotta love that plate cap not connected to anything.,..
Sherwood Posted August 19, 2013 Report Posted August 19, 2013 A rollable tube power supply (using mercury vapor rectifiers) to bias cables, built by Mikhail. Jesus, the world was crazy 5 years ago.

What tubes does it use? Best, Andrew
guzziguy Posted August 20, 2013 Report Posted August 20, 2013 Wait, Mikhail lives in Greece now? No wonder they went bankrupt. 2

Voltron Posted August 21, 2013 Report Posted August 21, 2013 The cable had to be in contact with my leather couch, and held just right for it to happen. 1
deepak Posted August 21, 2013 Report Posted August 21, 2013 Cheap too, roughly the cost of a used Extreme
Grahame Posted August 21, 2013 Report Posted August 21, 2013 At last , a valid use case for cable elevators (couch edition)!
Voltron Posted August 21, 2013 Report Posted August 21, 2013 I put in the cap isolated cables, and the radio station is gone, except if i hold the cable headphone cable just right, i get 91.7 XVXU, which is our local FM station clearly enough to understand it, with the volume pot all the way up. Anybody have an explanation for that? It's my understanding that I should't be able to pick up FM on this kind of equipment, but I heard the station ID, and there isn't an AM simulcast in this area. The cable had to be in contact with my leather couch, and held just right for it to happen. Sitting on my couch, right next to the rig, is where I intend on doing some listening, so having the cable able to touch the couch is a little bit important... While I was mostly kidding around, how often are you going to have the volume pot all the way turned up with no music on and hold the cable in just the right way for reception to occur?
spritzer Posted August 21, 2013 Report Posted August 21, 2013 All the time, Jacob is too cheap to spring for a radio... If it is mono FM then it could be picked up in some form.
Dusty Chalk Posted August 21, 2013 Report Posted August 21, 2013 I posit that the couch is demodulating the FM and then remodulating it into AM and then retransmitting...who am I kidding, I got nothing. WTF? How many gypsies did you piss off?
jdkJake Posted August 22, 2013 Report Posted August 22, 2013 Are you gonna buy it? No, that would seem a less than prudent purchase. That said, have to admire the tenacity of the seller or lament the gullibility of the perspective clients.
guzziguy Posted August 22, 2013 Report Posted August 22, 2013 gremlins and pixie dust mil-spec gremlins and pixie dust? Cheap too, roughly the cost of a used Extreme Jacob is in trouble then. He ate the cookie.
spritzer Posted August 25, 2013 Report Posted August 25, 2013 (edited) Here is something for people who think the L-2 is a bit plain looking... It's my birthday present from Kevin and along with it came the L-2 power umbilical. I can finally move the amp now as the temp cable was just a fire hazard waiting to happen.
