| Isolated ground in dedicated room/new construction? Immatthewj- Just for your reference then if you ever sell it that is the SLA-70B Signature version 2. If you add high quality coupling caps and a beefed up power supply (more electrolytic capacitance and big polypropylene bypass caps) it’s very go... | |
| Isolated ground in dedicated room/new construction? Immatthewj- That was/is a good little amp. The bad thing was having to take the bottom off the amp to go in and bias it. Never could figure out why Dennis did that. Hopefully you drilled a hole in the chassis and mounted the bias pot and mount a... | |
| Isolated ground in dedicated room/new construction? Would you please explain to me the reason for not using metal boxes? I would have thought (just guessing) that a metal box that is grounded by the conduit would act as a shield around the outlets. What is the reason for plastic boxes? Thanks! | |
| At this level of high(er) end audio why not offer balanced connections? I stand corrected atmosphere. I shouldn’t have thrown that statement out there that way. My mistake for stating it that way. | |
| At this level of high(er) end audio why not offer balanced connections? Typically if the circuit is not balanced the XLR input comes in and the positive phase runs through the normal circuit and the negative phase is just run to ground through a resistor like 100K or whatever they’re input load is. Or as I mentioned a... | |
| At this level of high(er) end audio why not offer balanced connections? What really matters is if the audio equipment has a “true balanced” design. Meaning that there is identical circuits for the positive and negative signals. This means twice the parts and cost pretty much. Twice as many tubes or transistors and a h... | |
| So I was changing a lightbulb last night… For AC filtering of the light something of this nature might work. They need to be wired inline to the dimmer switch. These particular ones are way more current then you need but I was looking up units that would cover at least 2-1/2 amps for my ... | |
| So I was changing a lightbulb last night… dirte30 - That would probably help with RFI. Different sizes affect different frequencies. It can get pretty technical trying to examine the line noise for the frequency or frequencies that are causing the problem. But if you have some lying aroun... | |
| So I was changing a lightbulb last night… I loved buellrider97’s quote of “ Hold the TV antenna “. I remember hearing that as a kid. I’d just touch the big metal tv channel selector know and the picture got better. My dad and older brothers would tell me to just stay right there! Don’t m... | |
| Ultrasonic record cleaners The Vevor comes with a 24V walwart supply. I’ve seen a few others in the forums also use a lower voltage supply to slow the motor down. The unit just cleans better at a slower speed. I’ve been using the variable supply for about 2-1/2 years now wi... | |
| Ultrasonic record cleaners Mbs3 - This is the exact setup I have. Really excellent results with it! I know the best results would come from a machine that can do a frequency of 60kHz to 70kHz but the price for those goes up dramatically. For people on a budget but really w... | |
| Ultrasonic record cleaners Whart - Yes, your cautionary message is correct. You do need to be careful of the alcohol. I only use a small amount in the mixture. About 1/2 a cup in close to 1-1/2 gallons of distilled water in a vented area. Some people don’t want the alcohol ... | |
| Ultrasonic record cleaners When I got back into vinyl a few years ago (and so glad I did) I broke down and purchased a Vevor 6L ultrasonic cleaning machine directly from them on sale Less then $200 and we’ll worth it! Years ago I had the upper level Nitty Gritty machines an... | |
| Are Their any Tube Preamp with Home Theater Bypass? The Cary Audio Design SLP-05 preamp has a perfect HT Bypass. When switched to HT Bypass the incoming signal only travels through a couple relays and back out the jacks. So no active circuitry in the signal path. Just in one jack, through the re... | |
| Does a turntable make a DRAMATIC difference? VTA, tracking force and alignment are everything! I’m pretty sure this is why some people buy an album like a 180 gram or 200 gram and give totally different reviews on the sound quality of it. One says it sounded very dull and lacked highs and... |
