Well never had this happen. I was testing each channel with speakers using Banana plugs, channel one would not produce sound. With a fair amount of switching things around I noticed I got a bit of audio momentarily on the channel. So I started schecking for loose connections. I notice the terminals were not screwed in and decided to just connect speaker to binding posts without banana plugs and it works fine. Just loose terminal. After that I screwed them in and tested with Banana plugs and all works, what a relief.

This could be investigated technically, but it seems people are more inclined to the assessment of their ear. Properly understood, all the loading really does is adjust the frequency response of the TT output, particularly in the high frequency range above 10kHz. Setting the load resistance too high will cause a spike in high frequencies right before the 20kHz roll off. This will create a shrill sound. Setting too low will cause a gradual roll off at about 8-10kHz, which will sound muddy or muffled. Starting at 100ohms for the Denon means going up to 470ohms will have a very small effect, if at all. Going up to 47k ohms will have a major effect, as well as going down too far like 10 ohms. The Nelion phono board has a 150ohm setting, so that should suffice very well. At the very least a great starting point. Moreover, we shouldn't forget that most pre amp's have tone controls, and if ever there was a good use for them, TT cartridges would qualify exceedingly. So if some strange (or superstitious) reason one doesn't feel comfortable with the loading scheme, the very same effect of dialing the loading can be made much easier, and perhaps more satisfying to certainty, with the tone controls.

Capacitance is more dependent on your cables, IIRC.

From Denon's User guide: Load Impedance 100 ohms min. (40 ohms when using a transformer) On my 1980 Pioneer SA-9800 integrated amp, there are also settings for capacitance. Do you have to worry about that? The settings available for moving magnets are: 100, 200, 300, 400, 500 pF 100, 10k, 25k, 50k, 100k Ohms

Been an audio fan for a while and used to drool over the Carver stuff at Circuit City but could not afford it then. I now own a few and have passed on a few. My current list of items is below, an odd mix probably 2 X C-1 M-1.0t M-1.5t AV-806x recent purchase but channel one not working sold: CT-17, TFM-4.0, TFM-15CB, TFM-25 Non Carver Yamaha M-85 Bryston 4B 2X Bryston 2B-LP Adcom GFA-5800 Speakers: Dalquist DQ-8 Dalquist DQ-28 Klipsch KLF-20 Klipsch RF3 II, RC-3 II, RS-3 II Infinity Kappa 7 Magnepan MMG Vandersteen 3a Signature with dual 2Wq subs Bose 901 Series V Bose 301 Series III Other PreAmps: 2 X MingDa MC-7R NAD 106

Yes not far at all. I got my two Vandersteen 2Wq subs out of Austin and had roadie service bring them to me. I have seen some nice gear go for sale in your area.

For most audio signals, this isn't an issue. But a Moving Coil's output is only 0.3mV, with a peak voltage of about 4mV with music dynamics, with a vast array of capacitances and inductances and impedances already inherent in the cartridge. So any cable capacitance will add to the low pass filter that already exists, and with such small voltages, the high gain stage of the phono preamp will amplify everything coming out of the cartridge/cable filter. As I said, this could be investigated technically, but it's complicated, very complicated. I would hate for listeners to be too worried about the cables, but at the same time totally neglect them. Suffice to say, it's important to realize that the sound 'quality' is not the same as the frequency response, in that, a high capacitive cable will cause some kind of intolerable distortion or compression of the dynamic range. There are many things to consider, but I think if we understand that the tweaks we are making for loading is to reach an acceptable frequency response, as opposed to trying to affect the overall quality, we can rest easy. An example of loading: Notice that the major differences exist starting at 8kHz-10kHz, and that some fairly major changes need to occur to make that much of a difference. So cable capacitance shouldn't be too much of a worry if you're using good ones.

Actually, for a good audio cable it's actually pretty negligible. For a 3-ft long cable, of good quality, you would expect less than 50 pF. However, I don't really know what the recommended loading is for today's phono cartridges, especially moving coil. Back in the day, people rarely used moving coils simply because of their extremely high cost, very delicate nature and the fact that we had plenty of moving magnet cartridges that were outstanding. The selection of cartridges today is dramatically smaller. RIP Shure V15 Type V MR I have two of the above with the stylus in excellent condition, but my guess is the rubber compliance parts after 30-40 years are probably not in good condition.

Welcome to the site! There is a great group of people here and they are willing to help increase or decrease your list of equipment. 🙂

Welcome to the OCCD club @Java1960! You have a nice collection of gear already........grin. Most of us are collecting gear in our later years because we couldn’t afford it then. It’s fun, and it sounds good. Thanks for joining us and enjoy the site!

Absolutely a factor !

Jim Clark @AR9jim, let me evaluate and review an ELAC PPA2, I kept it! It does a great job with my 30ohm MC cartridge! I sounds fantastic, let’s you dial in left and right loading individually, and as your listening! vinylengine is an excellent resource! barry

Denon recommends 100Ω

Welcome, @Java1960. I had the same experience..., drooled over Carver in the 80's, couldn't afford, now own more than I need. 😉 Truest definition of OCCD. Nice list of gear. Bet you like the 1.5. That TFM 4.0 is rare..., I have one, always looking for another to pair it with. post some pictures !

I set the Nelion board to 470Ω by default.

I'm lazy... I have that cartridge..., I just use the ELAC PPA-2 phono-pre to just "dial it in" using my ears... Picked up that unit from our good buddy Jim Clark, over at Jim Clark Stereo (Carver Tube Amp Dealer), here in IL. Never going back to researching loading, finding installation materials, reading tables of 6pt font, setting DIP switches ... LoL. 😉

Hello Java1960, and welcome to thecarversite.com. We're glad you're hear. There is a lot of information here, much technical know how, and a pretty good bunch of folks that are happy to help. I don't know of anyone in the Houston area, but if you don't mind shipping, @Nahash5150 is in central Michigan, and he does excellent work. www.nelionaudio.com He's also one of the administrators here. All of the techs here do great work, so you can feel safe choosing any of them to do the service/upgrades. Once you get to Novice status, please consider uploading some pics of your gear in the Members Systems area. We all like pics of all kinds of audio gear. In the meantime, kick your shoes off, turn up the music, and welcome aboard.

Yes just a bit too late, have the bug, need more room in my house
