| HELP.. power problems I however, must solve this at some point because my equipment is too expensive to allow it to continue.12-06-11: JprinzHire a good commercial/industrial service electrician to check out the problem. Show him my check list, previous post.. | |
| Audio Research VT200 Biasing Schematic ETC. Dischief,Not sure about the VT200 but the biasing of a VT100 mark 1&2 can be a bear if changing the small signal tubes along with the power tubes.If done improperly the new tubes and or the amp could be damaged. My understanding changing the p... | |
| Can i leave my HK 3480 preout not connected? Yes. | |
| HELP.. power problems I think Ericjcabrera is on the right track. A poor contact connection can cause arcing and arcing will cause RFI/EMI on the mains as well as airborne.Problem could be poor contact pressure of cheap residential grade receptacles as Ericjcabrera sai... | |
| Amp Hum Recently, I've noticed a significant hum coming through the mid's on my speakers.Key word recently..... "On my speakers" indicates both right and left channels. Could be a bad electrolytic capacitor/s in the power supply of the amp or preamp.If yo... | |
| Grounded Power Cord for Turntable - why not?? I understand the concern on creating a ground loop and in fact I have floated the ground on my other sources; but I never thought to float it at the device side. 11-13-11: AigengaJust to be clear here I am not talking about floating the safety equ... | |
| Grounded Power Cord for Turntable - why not?? The reason I want to change the lamp-cord to a shielded, high quality cord is to both give the TT cleaner power and to prevent emi from leaking out of the cord into the myriad of signal carriers that surround it.What you describe above would not g... | |
| Slight Tube 'Whistle' - Help? Hi. Thanks the preamp is the new CJ GAT. 11-13-11: Lloydelee21I would contact Conrad Johnson... | |
| Chasing 60 hz hum 11-10-11: KirkusActually I've experienced at least as many grounding-related problems with "double-insulated" equipment as those with safety grounds. This is because they still have leakage reactances in their power transformers, and thus AC-relat... | |
| Chasing 60 hz hum I've never been able to figure out how to navigate through long threads at AA in an efficient non-confusing manner :-),11-09-11: AlmargLOL..... That's why it's called the Asylum....Try this, it might be a little easier....http://www.audioasylum.co... | |
| Chasing 60 hz hum Al,Here is an interesting post that ran over on AA.Note the responses of the equipment manufactures.Plain and simple good sounding equipment can be built without the need of an equipment ground if the manufacture would only spend a few extra bucks... | |
| Balanced vs standard power Thanks for the help, guys. Jea48, even if I did that it can't be maintained with a three prong connector. Yeah, the best solution would be to pack them off and have them rewired to play together. I hate shipping them as one already has chassis dam... | |
| Balanced vs standard power See the second paragraph of page 2 of this Jensen paper. A key factor in how much hum reduction would result is the stray capacitance within each component between each of the two ac input lines and chassis, particularly stray capacitance in the p... | |
| Balanced vs standard power Dan_edJust curious have you ever checked the two amps for the proper AC polarity orientation?http://www.boundforsound.com/tweak.htmGround loop hum. http://www.jensen-transformers.com/an/an004.pdf | |
