Default Really low output from TT... Healp Please!!

Hi...

Background
A friend of mine gave me these TTīs, and I had them laying around (2 of them) for about a year now, and about a week ago I decided to have a listen. They are Technics DJ (canīt remember the model) TT and have the same cartrige on them.

Situation
I Conected them and for the first couple of hours they were playing fine. Turned them off, and came back the next day to play them for a while, and one of them did not sound, after turning the mixer (I am using a mixer as a pre) all the way up, I can hear some music, at this same level the other TT is way too loud. I have checked the mixer and both channels are working, I also tried exchanging Cartridges, and again, both working. So it is something in the TT and I have no idea what to check next. The way I understand it, the output goes straight from the cartrige, but one of the TT is killing it.... why???

Healp Please!!

You may want to check your grounding connections. Yes, I know....this shouldn't make any difference in the cartridge output whatsoever. But, it's been my experience that sometimes electronic voodoo takes place with turntables and mixers.

Try running without grounds, with grounds, one with/one without, then switching them....try all combinations.

This may not help at all, but it won't cost you anything either. Good luck

I also just remembered. Some of the Technics turntables will have a muting switch that kills the output. If the table is fully automatic, often the design includes a mute feature while the table is cycling, so you don't get a bunch of mechanical noise from the microphonic properties of a cartridge. Look and see......
