| Rare Vintage Find : "Norman Laboratories electronic crossover - amplifier System 12" This is my guess: The two RCA "input" connect to a preamp L and R output. The RCA jacks marked "amp" output low-pass signal (32, 100 or 200Hz) to two external power amp channels to drive L and R woofer. The two external power amp channels outputs... | |
| What Integrated Amp do You use My CODA CSiB V3 is a good match with Thiel CS2.4 Btw, the CSiB comes with 3 versions V1: 150 Watts per channel Class AB into 8 Ohms, 300 Watts per channel Class AB into 4 Ohms, Class A ~18 Watts V2: 250 Watts per channel Class AB into 8 Ohms,... | |
| I don't have sibilance problems, are my speakers dull? https://www.youtube.com/watch?v=uX_56DlHpfo https://www.youtube.com/watch?v=-tPcc1ftj8E Please tell me if your speakers have no sibilance problem. | |
| HTB preamp and AVR turning on the same amp. A y-splitter cable will work. But it is better to install a diode (1N4001 or equivalent) in series on each connector to prevent possibility of damages if AVR and stereo preamp both turned on at the same time accidentally. | |
| 12ax7 phono pre-amp tubes - plate voltage So I was troubleshooting Channel B cutting out when switched to RIAA (works fine in NARTB)... I powered it back up and the problem has resolved itself. Could be simply dirty switch contacts, btw, a receiver that old it is better to refresh all sol... | |
| 12ax7 phono pre-amp tubes - plate voltage https://www.thegearpage.net/board/index.php?threads/question-about-preamp-plate-voltages.1770030/ Please take a look at the harman kardon A-500 schematic, which is quite similar to TA-5000x minus tuner section, its only supply 170V to the phono st... | |
| Voltage conversion of Accuphase E-650 @eugene81 Congrats! Thanks for posting the photos. | |
| Amplification: what are the biggest advances of the last 40 years? During a recent visit at my local dealer, I inquired as to why the new amplifier we were listening to was so expensive? An Onkyo Grand Integra M-510 (1984-1992) will cost about $13k today’s dollars. https://audio-database.com/ONKYO/amp/m-510-e.htm... | |
| Voltage conversion of Accuphase E-650 https://photos.google.com/share/AF1QipOGrOpMMqsYdBSgXH2RZ5WAQr8ECpSKQ9lZeFPP-kK9lqHx94MR8pkv-HWnDXZq... connector K3 needs to be moved to K5 and connector K4 moved to K6 as pictured here? Yes. | |
| Voltage conversion of Accuphase E-650 @eugene81 Your link to the picture doesn’t work. Is your board similar to this one? https://tsuf4g.ch.files.1drv.com/y4pqy67e0jerv5cTcb-Fc8_ipC-EI1w1ykz_wR1ZBK_94kZcjKZQGJV5K16_Rt6XGkm... Please upload your picture to your system page and provid... | |
| Amplification: what are the biggest advances of the last 40 years? Better parts lead to better circuit designs. For example, output relay replaced by mosfet in Accuphase power amp to improve DF and protection. https://www.accuphase.com/technical_information/e-650_technical_information.pdf Also, you can’t build a ... | |
| Gustardx26 pro vs RME ADI2FS No doubt the RME choice of power supply is not critical due to its triple stage regulators. But some wallwart smps inject noise back to the ac mains, unless all components in the audio chain can handle/reject those noise, otherwise SQ will be a... | |
| Help! Source Output Too High for Headphones There is no volume adjustment on the Sony, unlike my Oppo 105D. Can I put anything in-line to reduce the output? A Goldpoint SA2 or Schiit SYS will do the trick, you can connect it in reverse if you want to use it to switch between two headphone a... | |
| Tripp-Lite Spike Cube Thanks for sharing! | |
| Is TDA7498E okay to work with DC 12V power supply? Power output is totally dependent on supply voltage. Yes.To answer OP's question, a DC to DC step up converter is required if use on a car battery. |
