| Double width studs for isolation? Lissnr,Did you check out the QuietRock 525? One layer of the 5/8" thick 525 is equal to 8 layers of standard 5/8" sheetrock. | |
| Double width studs for isolation? Also, I've never seen it in a store, but on some home reno shows on HGTV, I've seen a new type of sound absorbing drywall. It's a bit expensive. I believe it has a sheet of metal sandwiched between layers of gypsum. It might work through the stiff... | |
| Tube Question - Do they need time to "Break In" >>Thanks everyone for the response...I'm changing tubes for the first time...02-07-09: Chadlesko<<>>>>>>>>>>>>>>>>>>>>>>Chadlesko,New tubes do require burn-in time to re... | |
| VPI Scout- motor pops in speakers when turned off Mekong56,A DIY fix would be to wire a snubber circuit across the on/off switch of the VPI.Simple, a resistor in series with a capacitor paralleled across the switch's contact. Snubber. | |
| life expectancy of a cdp? Back in 1988 I bought a Denon DCD-1500 CD Player. Keep it for about 10 years then gave it to my daughter. She still uses it to this day. Trouble free, never serviced. | |
| On one leg or two legs? Amps are self biasing.02-04-09: Maril555Al,Thanks I missed it on the first read. | |
| On one leg or two legs? A bad tube can definitely cause a buzz and a bad electrolytic in the power supply can cause a hum. I would also think a leaky cap in the signal path could cause a hum.You might want to send an email to BAT customer support and ask them.You never a... | |
| On one leg or two legs? I would take the noisier of the two amps back to your friends house and have him connect it to one of his speakers...... Take along the power cord and the speaker cable. Take along your multimeter too.If it does not hum/buzz there, &^#@$%#@, C... | |
| On one leg or two legs? Hevac1,The two pole 60 amp breaker will trip just fine if there is an overload or short circuit on just the one pole of the breaker. It is designed to do so. I assume the reason Maril555 paid to have the sub panel installed was to keep his audio b... | |
| On one leg or two legs? BTW, what's your take on the high chassis voltage, higher with the correct polarity?02-01-09: Maril555Well the lower chassis to equipment ground voltage is the correct orientation polarity for the amps. Seems odd to me both amps would have the pri... | |
| On one leg or two legs? The measurements are good......The bad news is it does not help the hum problem. From the pictures you supplied of the sub panel what I could see the electrician you hired did a good job. The only code violation I could see was the (4) 30 amp brea... | |
| On one leg or two legs? Maril555, You misunderstood what I wanted you to do. All the test measurements are taken at the wall receptacle outlet only. No audio equipment is involved with the test. In simple terms the test will tell if there is a good electrical continuity ... | |
| On one leg or two legs? new measurements:L amp:Correct cheater plug 62.5 V.Reversed 51 V.R amp:Correct 62.5 V.Reversed 51 V.01-31-09: Maril555Wow, I could see where the reading might be high in one direction, but not high in both directions.I just checked my little ARC V... | |
| On one leg or two legs? Can I use a polarity checker, kind they sell in Home Depot, to accomplish the same, unless you meant to do this test for a purpose, other, than to check polarity of each receptacle?I cannot understand one thing, though- how come the hum is louder ... | |
| On one leg or two legs? Just did it again- no ICs connected, plugs in the inputs- same hum.01-31-09: Maril555Maril555, By chance do you have a multimeter? If so why not try a plug polarity orientation test for each power amp.To do the test you will need to trim the polar... |
