I've read that this unit works best with carts in the 3-5mV range. I have two carts, 2.5mV & 6.2mV. Will they not work well with this preamp?

Go to needle doctors.com and ask the question, these guys will have your answer!

Should work on both. There is a volume control so it will probably be a bit louder with the higher voltage cartridge. I have personally tried the Blue Point and Pickering and despite the huge price difference, the Pickering actually sounds better. (go figure) Good luck! Jim

It can't hurt to test but I drive these with a dedicated 200w amp. If the Preamp is putting out around 1w it likely won't respond.

You just need 12vs, and most carts run higher voltage. Add an isolated 12v deep cycle battery should do the trick.

In practice these things are pretty robust. As long as you do the adjustment while there's no output load (just your meter connected) and don't exceed the maximum rated input voltage, you're unlikely to fry it.EDIT: It sounds like one blew up on you, sorry to hear that. This is surprising to me, since the LM2587 has undervoltage lockout. I bench tested this for my application (dropping the input voltage until the thing turned off) successfully several times under 10W load.

i have used a smallamp and does work, did not buy thru amazon, was to expensive, I got it at Costco for like 65.00..was my 2nd one.my 1st one lasted 6 years[

I believe this should work but don't know if the schematics are the same. It has 2 stereo RCA inputs, phono and auxiliary, and 1 amplified stereo RCA output. You can adjust the output level on the output. I use this to run my turntable and jukebox through my Samsung TV Home Theater. There is no line in on the home theater, so without this preamp, the input is too weak. I am happy with the unit, and leave it on all the time as it uses very little electricity when not in use. I agree with the previous answer from Jeffrey W. Spicer.

It will likely 'work' but the results may not be what you are expecting, depending on what type of 'cartridge' your turntable has. There are basically two types of 'cartridges' used with turntables (a cartridge is that part of the turntable at the end of the tone-arm that holds the needle, and actually converts the mechanical movement of the needle into an electrical signal). The first type is a ceramic cartridge, and the second type is a magnetic cartridge. Although both work, the higher quality turntables have a magnetic cartridge. The practical difference is that the ceramic cartridge puts out a higher voltage that will typically work with an 'auxiliary input' or 'line level' input without any need for pre-amplification, whereas the magnetic cartridge puts out a voltage that is closer to a 'microphone' level voltage, and requires a pre-amplifier to boost the level to the 'line level' or 'auxiliary level'. If you are using a pre-amplifier with a magnetic cartridge, then yes this will very likely work for you. If you are using a ceramic cartridge, then yes, this will very likely work for you. If you are using a magnetic cartridge without a pre-amplifier, then this will likely still work, but the sound level will be significantly reduced. I use the term 'likely' because I'm not sure of the rest of your setup.

I have used it without grounding the preamp. It worked perfectly, and, the instructions say nothing about your question, so I don't think it is a problem to worry about.

More info is needed and I can tell you if it will work or not. Exacly what model is the preamp.The device should have stickers on it which tell how many watts it draws as well as the current mA

It will not work without a phono preamp. The output of the phono cartridge is to low. If you purchase a phono preamp and purchase some adapters you could make it work.

Hello Ryan, with my old Engl 100 Watts Amp it works really fine. I get exactly the distortion I need. Connect it via fx-loop. Greetings, Tom

my understanding is that this is the newer version and has a built in preamp. I would compare the specs at the Winegard web site or perhaps solidsignal.com

No. If you're looking for a recommendation, I'm using mine with a TC-750 pre-amp. I have no complaints.
1621477
I do not recomend that ... This is related with something like frequencies... Besides the boss device dosent have a good performances ... Otherwise the devices is usted for goes from high to low and what you want i Think is a convertor ...

Hooking this unit to your phono input will result in RIAA EQ being applied twice to the signal. You will get the boost but the sound will be terrible. You'd be also running the risk of saturating that input and damage it. The same company sells a MM/MC preamp for slightly more. I'd buy and use that instead.

I know this is an old post but it may help someone. Interesting that they'd say 9-12V. It will probably work, but this is what I know about car electronics. I'm a product design and electrical engineer and I've developed lots of products that plug into car cigarette lighter sockets. The 12V power is really "noisy" meaning there are spikes and jolts and surges all over the place. It's a nominal 13.5V on most electrical systems, though the newer cars with advanced electronics may clean that up a bit. But here's the deal: The "nominal" (average) already exceeds their 9-12V spec, and when you consider the spikes and surges, I'd think you'd be risking blowing out your DVD unit to plug it in with a direct 12V cord. The 9V cord not only transforms it down to a lower input voltage, but it has a switching regulator that adapts very quickly to quell spikes and surges. The replacement adapter from Philips is $12, but hey, that already fried! It probably didn't "fry itself", but more likely was fried by the car you used it in which may have had worse surges than the average car. I would get the $20 one from Radio Shack (m/n 273-369). Take in your player to a store and they'll fix you up with the correct tip in the right configuration. I'm not insensitive to your need for economy, but you are risking frying your whole $130 DVD player for want of $10 or $20 for a good power cord. Go without those Lattes for a week and get a quality power cord.

Your amp needs to be phantom power operable. Most P.A. Systems will have a phantom power switch to power the preamp. It's not so bad putting the 9v, you just have to unscrew the backplate and hook a battery in.
