| Hear sibilance on Krall, Famous Blue, D. Fagen? Rebbi,Sibilance is a manner of articulation of fricative and affricate consonants, made by directing a stream of air with the tongue towards the sharp edge of the teeth, which are held close together; a consonant that uses sibilance may be called ... | |
| Hear sibilance on Krall, Famous Blue, D. Fagen? Rebbi,I would try the Signal Cable power cord on the Music Hall cd25.2 CDP first, even if you are using it as a transport only.What are you using for a digital cable from the Music Hall cd25.2 to the DAC? I assume it is at least 1.5 meters long.. | |
| Hear sibilance on Krall, Famous Blue, D. Fagen? Rebbi,I have the Jennifer Warnes "Famous Blue Raincoat" and Diana Krall,"When I Look In Your Eyes" CDs. Neither of the two tracks you mentioned have sibilance problems when played on my system.I found this doing a search on the Web.Music Hall cd25... | |
| ARC VT-50 Damage/Repair Advice BIF,Jim, any idea why the 6922 bias pots are less weird than the power tubes pots?08-30-15: BifwynneThe 6922 bias pots are blue in color only and are not the same pots as used for the power tube bias pots. I believe they are a whole different anim... | |
| ARC VT-50 Damage/Repair Advice Hi Al, I suppose it's possible that the physical placement of the rectifier circuit and the filter capacitors could have provided some reduction in the likelihood that a short to that screw would have affected the other channel,Al, That was not a ... | |
| ARC VT-50 Damage/Repair Advice Bifwynne,Yes, that is why a pair of hook on probes should be used when biasing the amp.Sometimes I think the guy that designed the layout of the amp had a sick sense of humor. Also as I stated in an earlier post the bias adjust pots are really tou... | |
| ARC VT-50 Damage/Repair Advice Al,Here are a couple of pictures I found on the Web. This picture shows the Phillips head circuit board mounting screw on the right channel that I think the multimeter probe came into contact with causing the short circuit. This picture shows the ... | |
| ARC VT-50 Damage/Repair Advice I'm assuming, btw, that the B+ is generated by a power supply circuit that is common to both channels, which I suspect is the case but don't know for a fact.08-30-15: AlmargHi Al,VT50 Schematic and parts list.Note the two R30 10 ohm resistors on t... | |
| ARC VT-50 Damage/Repair Advice ^^ So...with the amp off; you clip your leads to the test points. Turn the amp on...let it run-up to operating readiness; and just see what the voltmeter reads?Wow; not to be ungrateful...but I sure could have used, a simple solution like that a f... | |
| ARC VT-50 Damage/Repair Advice Hiendpawn,I bought my VT50 amp new in 1997.Unless you listen to music really loud 45 watts per channel should be fine. At present I am running EH 6922 tubes and a quad of SED Winged C 6550C tubes I bought from Upscale Audio back in 2007 I had stas... | |
| ARC VT-50 Damage/Repair Advice At the 15 minute mark, I had the "tech" do it...so I could watch, and make sure there wasn't much to it. You just take your voltmeter leads, and touch them to each side of a test resistor. But at the 1 hour mark...I decided to give it a try. I swe... | |
| Output level inexplicably reduced- help For starters, do you have a CDP, DVD, or blu-ray player you could hook up to the Reference 3 preamp? If so I would start there. If you have plenty of volume output playing a CD then that will rule out everything downstream of the line level inputs... | |
| Audiophile Fuses One more thing, I also noticed the Synergistic Red Quantum fuses were slightly smaller diameter than Rat Shack fuses.I had to pinch contacts on Coincident screw in fuse holder to tightly grab the synergistic fuses.Surface area and poor contact pre... | |
| Audiophile Fuses Replacing 6.3amp with 8amp? 08-17-15: SnsThat's a 27% increase. You might want to contact Coincident tech support and ask them about increasing the fuse to an 8 amp slow blow fuse. Just curious, was the OEM fuse that came with the amp a 6.3 amp s... | |
| Audiophile Fuses Knghifi,Are the "SR Red, HiFi-Tuning Supreme, Audio Magic" fuses safety tested and Listed by any independent recognized testing laboratory?. |
