| Dielectric grease and tubes NO! Don't use it! | |
| Amp Shutting Down, need help Correction. Should read, Then I got into a discussion with Jon Risch which I apparently got confused thinking SMPS could also be used with a power transformer.Anybody ever wonder why the hell the user cannot edit a post after xxxx amount of posts ... | |
| Amp Shutting Down, need help If it has large toroids, there is no SMPS. A SWPS might look like an aluminum box inside the unit, but certainly would not sport any toroids, especially large ones. 09-13-12: AtmasphereRalph,Thanks for the response. My limited understanding of SMP... | |
| Isolation Transformer and Subpanel recommendations it became clear that some of my responses and my not being an electrician have caused confusion on the thread. Apologies all around for this...09-11-12: Zephyr24069Zephyr24069,For a layman I thought you did fine.Asking questions is a good thing.It... | |
| Isolation Transformer and Subpanel recommendations End result is better quality power to my system; the dedicated circuit, rebalancing the house panel to make the dedicated circuit the first one off the main, all other high current circuits on the other leg/phase of the house panel, good quality w... | |
| Amp Shutting Down, need help Switch mode supply??! I figured this thing had a big toroid...Hi Ralph,Yes it has two big toroids. Am I wrong in my thinking the amp could still have switch mode power supplies?LOL, it wouldn't be the first time I have been wrong..... Jim | |
| Amp hums in standby mode when TV is on Gbart,Thanks for setting up and running the bench test experiment.The reason I asked the question is so the user of a DC blocker could install the blocker on the known offending device or piece of equipment. In this instance the OP's TV instead of... | |
| Isolation Transformer and Subpanel recommendations I currently have a 100 ft run of heavy flex conduit for my dedicated circuit;09-11-12: Zephyr24069If you put the new panel in the garage are you saying the new branch circuit/s run, from the new panel, would be 100' or more?I had an electrician pu... | |
| Amp Shutting Down, need help Jim -- I don't see the 117V being indicated as a minimum. I would assume it is intended as a nominal value.09-11-12: AlmargHi Al,Ya, I agree. I knew better... I'll just have to blame the thought on a brain fart moment. 120V may be the nominal volt... | |
| Amp Shutting Down, need help Sailcappy has verified the mains voltage at the dedicated branch circuit receptacle is 118V using a true RMS meter. That is only one volt above what the manufacture recommends for the amp.09-10-12: Jea48 That is only one volt above what the manufa... | |
| Isolation Transformer and Subpanel recommendations So the transformer could be mounted in the garage and fed from the main panel relatively easily.From the new transformer the load feeder could pass through the ceiling across the attic and drop down through the top plate into the wall cavity to th... | |
| Amp Shutting Down, need help Hi Ralph,I learned a couple of weeks ago from Jon Risch, an EE as you know, that a SMPS will draw more current if the voltage sags to try and maintain output power of the PS.Sailcappy has verified the mains voltage at the dedicated branch circuit ... | |
| Amp hums in standby mode when TV is on Gbart,My bad.Thanks for the heads up.sae_2300@optimum.net.Gbart, I have a question for you.... Assuming the TV's SMPS is putting DC back out on the mains what would happen if a DC blocker was installed between the TV and mains power receptacle? Wo... | |
| Isolation Transformer and Subpanel recommendations my plan is to install the transformer in an adjoining attic over a garage where any humming from the transformer will not be hear and any heat will dissipate.Not a good idea..... I doubt you will find a licensed electrician that will do it.Why no... |
