| Synergistic Red Fuse ... Would an external fuse holder with a battery ac oss the leads to get an amp or two across suffice?Household alkaline batteries would at best only last a few hours when supplying that much current, and in many cases less than an hour. Also, you wo... | |
| Help With 60Hz Hum PLEASE Hi Jim,When I first looked at that photo last night I interpreted it the same way as you did, that two pins (probably 1 and 3) were jumpered together. But after noting Joe’s statement that:I took the XLR cable apart on both ends and both end have ... | |
| Help With 60Hz Hum PLEASE Thanks for providing the documents, Joe. After looking at the schematic I withdraw my suggestion of RCA shorting plugs. Consistent with your earlier comment it shows the center pin of the RCA connector being wired directly to pin 2 of the XLR co... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? I don't know the answer to that question, Mark. In part because I have no experience with integrateds in recent times, and never in that kind of price range. And in part because we haven't been able to arrive at an understanding of what is prese... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Hi Mark,I have no experience with the Whest phono stage, but based on all that I’ve read about it I too would expect it to be very quiet with a Lyra Delos, which is rated at 0.6 mv output under the standard test conditions. And since the phono sta... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Get a SS amp with proper input to match your pre amp and I assure you, the issue will be gone. Matt, sonics **might** be better, but the noise issue (which the OP has stated is the main concern) will not be gone. See the posts above by me and by R... | |
| Help With 60Hz Hum PLEASE Hi Jim,Please consider the paragraph in my first post of today in which I used the word "floating." And in doing so, re your comment that: ... the Signal ground of the Adcom was extended through the IC to the chassis/signal ground of the Marantz.... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Am I wrong in feeling funny about 3 o’clock on the volume to get a rockin’ experience? Seems like the high dial position is pushing the ability of the preamp too far. No, I doubt that is the case, Mark. In fact many believe that having gains and s... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Hi Ralph,Those were exactly my points! Although if I am recalling Mark’s previous thread(s) about the noise issue correctly, the noise performance of the phono stage is also suspect, as well as the performance of the preamplifier.Best regards,-- Al | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Ahendler got it right.Not sure about that, Ralph. His statement that:You need either a preamp with more voltage output or a power amp with higher input sensitivity. ... does not appear to be consistent with what I said in my post above, and I the... | |
| Help With 60Hz Hum PLEASE Please explain your reasoning for when connected to a preamp that is powered off being the same as the cable not connected to anything, open ended. Hi Jim,While the output impedance of an unpowered solid state component is probably unpredictable i... | |
| Will Changing my 100 Watt Tube Amp to a 200 Watt SS Amp Solve My Problem? Hi Mark,If the noise only occurs when the volume control is turned up to a relatively high setting, it means that the noise is being introduced into the signal path "ahead of" ("upstream of") the volume control. A more powerful amp will often (alt... | |
| Help With 60Hz Hum PLEASE JO3533, yes by all means try to somehow post or link to the schematic you have for the amp. I’ve tried to find one online and have not been able to.Jim, a couple of your recent statements have touched upon what I’ve been thinking that led me to su... | |
| Vibration Control for Lightweight Tube Components The preamp sits on a shelf enclosed in thick wood (pine) open in front and back. If the shelf is tapped on, it may create resonances surrounding the unit thru the sides and shelf above it. These resonances may be picked up by the exposed tubes whi... | |
| Vibration Control for Lightweight Tube Components Lowrider, I’d suggest trying Mapleshade Isoblock 1’s, or the lower priced generic equivalent that I think may be findable at Home Depot or elsewhere. Assuming that their 1.75 inch height can be accommodated. I say this even though the description ... |
