Tube amp down, need guidance from the experienced Ditto advice ARC gave me. 2000 on power tubes -- that's a max Q!! | |
Vintage Crown D 150A II Amp -- How good was it? Fjp, I'm NOT suggesting that you repair the Crown in light of the comments above which kinda "dissed" the amp. But if the problem is just some power supply and/or electrolytic caps and some transisters, and if you have an emotional attachment to t... | |
Please Help Ambient Bass Resonance Sound-Real-Audio, thanks for the thought, but I don't think my phono pre, linestage or amp clipped. If I didn't mute the phono stage, who knows what would have happened. But I muted the phono pre as soon as the oscillation became louder. I think S... | |
Please Help Ambient Bass Resonance String..., I think you're onto something. I just tried something that is a temporary patch that seems to have nearly eliminated the bass feedback. I have furniture pads that are used to stick onto the bottom of heavy furniture to prevent scratchin... | |
Please Help Ambient Bass Resonance Al, quick follow up Q. Do you think using the 3 gram headshell weight would change the resonant frequency, perhaps ameliorating the problem?Regards,Bruce | |
Please Help Ambient Bass Resonance Thanks Al, I tried the grounding idea already. No change. Not a lot of options about moving gear around. My wife finished the basement, carpet furniture, etc and there's simply not much I can do. So far, the double rubber washer trick seems to hel... | |
Please Help Ambient Bass Resonance Thanks for all of the suggestions. I think the idea that had the most chance of working was moving the TT further away from the speakers. It didn't really make a difference. The best thing I've done so far is to use an extra rubber washer with the... | |
VPI Ceramic Platter I have a question -- not a comment. I have a Classic "2.5" TT, which has the original smooth platter. The question is how much difference can there really be between a smooth versus groved side wall platter when we're talking about an 18 pound spi... | |
Class A Watts Ralph (Atmasphere), Class A, AB, etc aside, I think it's also worth mentioning that many tube amps use negative feedback which reduces the output impedance at the taps. I would surmise that if a tube amp's output impedance off the 8 ohm tap is 1 o... | |
VPI Ceramic Platter I'm a happy VPI customer!! Mike just sent me a Classic 3 tonearm bearing base to upgrade my Classic 1 base. Installation was a snap. Mike sent me all the tools, jigs, taps and alignment tools needed to show where and how to drill the new holes in ... | |
VPI Classic 4, any one have it? Stringreen, any idea why the ceramic platter would make a difference. I use a SS delrin clamp and flattening ring. Sound seems pretty good to me. I concede that using the black fiber mat tends to over damp the record, but I'm just a bit confused a... | |
VPI Classic tweak Just a thought. I wonder if putting an extra belt on the platter/motor mount could prematurely wear the motor bearings because of extra tention on the drive shaft and bearings. I'm not sayin' ... just asking. | |
Audio Research Reference 5SE reliability Anwar, seems like you just squeeked under the wire. You might still want to call Kal to get his view on whether you might gain any further sound improvement if the output impedancce could be tweaked up just a bit more.CheersBIF | |
90db 4 ohm with tubes? Thanks again as usual Al. As I said, it took a while for your tech explanations to finally sink in, but I think I now have the gist of it. As it turned out, the S8s (v3) changed the cross-over a bit from the v2. Paradigm told me that the max imped... | |
90db 4 ohm with tubes? Al,Just a quick follow-up to your last post. Copied below is an excerpt from the ARC web site that specifies the VS-115's output regulation:"OUTPUT REGULATION: Approximately 1.2dB 8 ohm load to open circuit (Damping factor approximately 8)."I assu... |
