New Ground Loop - What Could Have Caused?
including Verizon FIOS box and TV,If it is indeed a ground loop hum problem I would start with isolating the CATV coax cable from the Verizon FIOS box. Disconnect the coax from the box, check for hum.If the hum is gone buy a ground isolator and in... 
Interested in the history of the vacuum tube?
Would like to add this one as well.Electrons on Parade part 1.Electrons on Parade part 2.. 
Can a F connector substitute for balun?
Will not cause any damage but more than likely will not work properly.http://www.antenna-theory.com/definitions/balun.phphttp://www.antenna-theory.com/definitions/balun.php. 
Stylus Riding Too Low?
Kldonne,Here are a couple of videos that might help.Watching the videos it appears the arm is higher at the back than at the front with the stylus resting in the record groove. Did you remove the three shipping transport screws?Make sure there is ... 
Stylus Riding Too Low?
I noticed that the rear of the tonearm is actually so low that it touches the album as it progresses so that seems to be the cause.That can't be right. Sounds like the VTA at the pivot is too low.Are you sure the platter is seated down properly on... 
Heat + air conditioners blasting = CDP won't play
Adamg,I brough the player home and turned on all components. I have an Audience Adept Response R12 power conditioner that displays the voltage from the wall. It is normally 112-114 during the day and up to 117-118 in the evening. It is currently a... 
Two physical grounds??
Tjtrout20,The cold water pipe is part of the Grounding Electrode System. The key word is System, which includes the cold water pipe. Check 250.50 for description of GES. You need to go back to the book.... Only the first 5 feet from point of entra... 
Two physical grounds??
Tjtrout20,In Gs5556 defense he may live in an area were all branch circuits must be installed in conduit. I believe Chicago as well as New York City being two that come to mind. He may have just had a brain fart and forgot not everywhere in the US... 
Two physical grounds??
Try running a #14 awg to the outlet that your power conditioner is using, to a cold water pipe and clamp off to that. 07-07-11: Tjtrout20Tjtrout20,No longer an NEC approved method. Not since 1996 I believe. Too many plumbers were getting shocked o... 
Two physical grounds??
Gs5556,Metal boxes were used with old 2 wire NM sheathed cable. The metallic box is floating..... Even in the case of old BX the conductivity continuity of the armor/connectors would be poor at best.Jim 
Cassette Deck??
I have a Nakamichi 500 I bought new back in, I believe, 1976.It still works just fine. . 
When does a 5V4G/GZ32 have to be replaced?
I do have schematics of my amp. In particular, unlike the Dynaco, in my case 5V4G has its own secondary that is used just for its filament, so there is no high potential there.06-21-11: MeisterflohIf you look at the data sheet for the 5V4 you will... 
When does a 5V4G/GZ32 have to be replaced?
Meisterfloh,Get it tested or just buy a new one....It would seem to me if the tube were to short you could burn out the 5 volt filament winding or possibly the high voltage winding of the power transformer. The tube is by far the cheaper of the tw... 
Surge Suppression vrs. Lighting and Power Spikes
I would bet most residential earth grounding electrodes are inadequate when it comes to lightning protection.If memory serves me right the maximum electrode to earth resistance of 5 ohms per IEEE. http://www.cpccorp.com/deep.htmhttp://www.erico.co... 
Surge Suppression vrs. Lighting and Power Spikes
Problem with grounding is that it has to be done (to be legal and insured) with at least gauge 10 wire to ground rod with bends of no smaller radius than 6".06-13-11: Kijanki Kijanki,You are correct on the size of the wire. #10 awg copper or #8 AW...
