| component grounding I've been zapped plenty of times by ungrounded equipment. I used to do most of my hobby work in my little shop in my basement. Eventually I learned to plug the equipment into an isolation transformer since the zap factor could be unpleasant. | |
| Owners of Carver Crimson 275 -Caution/Warning--Potential Increased Risk of Electric Shock Being a tube power amplifier we have lots of high voltage wiring besides the power supply. In case of a high voltage short to the chassis that high voltage and current gets carried by the delicate ground in the interconnect wiring, which is then... | |
| Balanced vs RCA between amp/preamp You suggest to use transformer isolation and you deny the way to use it. What is your opinion? Audio Research reply directly that I should use transformer coupled to connect RCA pre with their XLR only power amplifier. @runwell If you are ... | |
| Owners of Carver Crimson 275 -Caution/Warning--Potential Increased Risk of Electric Shock I would be willing to bet you do not fuse the AC mains neutral conductor in your equipment. The correct way is Hot from the IEC inlet connector to >> fuse to >> switch... Fuse as soon as possible inside the equipment. @jea48 You ar... | |
| Owners of Carver Crimson 275 -Caution/Warning--Potential Increased Risk of Electric Shock LOL all of Bob’s equipment doesn’t connect to safety ground, because it’s not needed and there’s no risk of electric shock. All it takes is the switch shorted to chassis and you can have a problem. That could happen easily in shipping. OTOH If ... | |
| Balanced vs RCA between amp/preamp " The problem with this approach" Do you mean Transformer coupled approach? @runwell No. If you are dealing with a ground loop, the transformer can fix that, but take @ieales' post seriously. | |
| Balanced vs RCA between amp/preamp So finally it goes down to the transformer isolation,it seems the usual way even the XLR output from the pre,they usually get the rca signal first and use the transformer to get the inverse signal and consist the XLR sigjnal. If the preamp has... | |
| Any Technics 1200GR Owners With Arm Upgrades? https://systems.audiogon.com/systems/7164 This is one we did a few years ago. | |
| Balanced vs RCA between amp/preamp I just want to have a solution between RCA pre and XLR power amp, it seems the transformer coupled is the simple way to go. It is. A set of Jensen ISOMAX line transformers should do the job. They make one that has RCA inputs and XLR outs. ... | |
| Balanced vs RCA between amp/preamp @runwell Yes. We patented the use of a Circlotron output (which is direct-coupled and balanced) with a servo control to prevent DC Offsets from appearing at the output. The Circlotron is a push-pull circuit that allows for entirely symmetrical ope... | |
| Peeking inside a Carver Crimson 275 Tube Amplifier I'm just not sure how this thing could test out near 75w with that 15w Edcor OPT in mine from MusicDirect. It won't. As far as I can tell from the photos, that output transformer is a custom unit. But its still a 15 watt device and will satur... | |
| I'm confused - Different music...different speakers? @smaarch1 Your ears can act as a tone control to a certain degree. If the bass is missing the ear will tilt things towards the treble. So if you add a sub (and have it placed properly so its audible at the listening position) you'll find the highs... | |
| Grounding cable gauge size @ozzy I looked at the Entreq site and also read the manual for the boxes. They only have one wire from the component to the box. When a cell is used in a box, it can only be used for one component so there are no other 'ground' wires connected to... | |
| Phono input cap to preamp @wturkey Measure the voltage on the output side of that capacitor. If the input circuit employs a discrete device like an FET or transistor, there may be a voltage present to bias that device properly. Getting rid of the cap could thus cause the c... | |
| China built tube amps If you get a Chinese amp that is sold by a US dealer you should be fine. I would avoid the cheaper Chinese tube amps that only seem to be available on Amazon or eBay. There is a reason they don't have dealer support! We avoid Chinese parts in our... |
