I have humming and noise using phono stage on my setup. It's readily apparent if there is no LP playing and I turn the volume up. This can be heard via speakers, and via headphones.
Here is a list of my equipment:
Technics SL-1600 MK2
Ortofon OMB 5E cartridge and stylus
Marantz 1120 integrated
Audio Technica ATH-M35 phones
set of Pinnacle AC500
set of Infinity RS2
Some more background:
I mostly listen to classical vinyl, with an occasional rock or rap.
I have the turntable correctly grounded to the receiver.
I balanced and aligned the stylus, and cleaned it with Mr Clean Eraser
I had a different receiver hooked up before with the same results: Fisher CA-800
I also tried a few different Marantz pieces (1070 and 2270) as well as full Nikko amp/preamp/EQ system and got more or less the same results
I tried another TT, Technics SL-QD33 with Ortofon TM 7 cartridge/stylus, which is similar to OMB 5E - also noisy
My main suspect areas are:
1. Noisy phono stage. How would I fix this? Will it help if I do a re-cap of just the phono stage? All other inputs sound nice and clean. I love the Marantz but I mainly got it to improve my vinyl experience, and if it don't help, it's going bye-bye. Is a new external phono stage in order?
2. Cartridge and stylus. I realize this can be fixed with lots of money for a new cartridge and stylus. But I am reading that the stylus is not a bad one, and I cleaned it really well with Mr Magic Eraser and examined it using a loupe.
3. Maratnz came to me without the proper amp-preamp jumper cables. I am using a regular set of RCA cables. However, the noise is not present when switching to any other input, so incorrect jumpers aren't likely to be an issue.
Please help. I don't want to needlessly throw money at problems and taking wild guesses. Thanks in advance.
