| 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... | |
| SUT Interconnects 20pf/foot is a practical value for a cable. Mogami makes a console cable that specs in this area. Since transformers can receive either a single-ended signal or balanced, you could run a balanced connection from your arm to the SUT and thus obviat... | |
| Any Technics 1200GR Owners With Arm Upgrades? Nice. Thanks for the feedback! Anyone else have ideas or experience on this? I like doing mechanical and car/engine type work...but I am very intimated messing with setting up Turntables. I designed an armboard to replace the stock arm locatio... | |
| Are cutting lathes VTA constant across the board? Or do different mastering engineers have preferences on the angle of the cutting head? If they have differences, isn’t fine tuning VTA on you turn table just going to run you in circles with each different lol you play? The cutter head has a st... | |
| Want to make sure I have the correct settings for my phono pre-amp Cartridge loading is for the benefit of the phono section not the cartridge, which does not care a bit how you load it unless you get too low- at which point its output will decrease. FWIW a LOMC cartridge cannot 'ring' (distort) at audio frequenc... | |
| SUT Interconnects Could you please explain why it is important to have low capacitance cable before the transformer. how does that affect the transformer ? The inductance of the cartridge and transformer in parallel with the capacitance of the tonearm cable caus... | |
| Grounding cable gauge size I also had a residual noise when I used your Atmashere amps. It is inherent in tube amplifier designs. With all due respect, you really need to try this type of grounding before you comment. It would probably surprise you, as it did me. Its tr... | |
| Does anyone manufacture an alternative Linn Sondek belt pulley ? If you are needing an idler pulley and you have the old one, whether a turntable or tape machine, you can get it rebuilt by Russell Industries for a reasonable price. For many years it was only $35.00; I got a capstan pinch roller rebuilt there fo... | |
| SUT Interconnects I always though it was more critical to keep capacitance low AFTER the SUT, rather than BEFORE the SUT, becasue of the after-SUT’s capacitative load supposedly "reflecting back times the sqaure of the turns ratio" (i.e. the opposite of what happe... | |
| Peeking inside a Carver Crimson 275 Tube Amplifier It's a video of a Suntan cap blowing up. Those are electrolytics, quite different from what is used for coupling caps in tube gear! |
