Seton TUS 600 low output

[fatboychief]

I have a seton tus600 tuner that has a very low output on the “output” jacks. 1, would it hurt anything to just use the record out to feed the amplifier and 2 are there any simple things that may be causing this. I have some test equipment and basic knowledge of circuits. But any help from you experts would be great. Btw. I hooked it up to a cheap receiver on the rec out jacks and everything works fine, just wanted to make sure before I hooked it up the the matching setton amp that it wouldn’t hurt anything . Thanks

Unless your tuner has variable output, line out and rec out is the same thing so you can use the rec out. Won't hurt a thing. Can't imagine why you would think that.

Cause one works and one doesn’t. Obviously they are not the same output. Just making sure one didn’t have a higher output level or something crazy ‍

I assume you have turned up the level adjustment? Perhaps that control is dirty.

They are the same. sorry, I assumed you would know that.

One is fixed, one isn't. If there is a level control, it is connected to the exact same spot as rec out.

My Pioneer TX- 9200 tuner works just the same.

Your tuner may have muting transistors or a relay on the normal output but not on the record out. Go ahead and use the record out. There could be a problem in the muting circuit or it could need alignment.

I could be wrong but doesn't a muting circuit only pertain to getting rid of fizz in between stations?

I cleaned the control today. We’ll see if that helped any when I get hooked back up.

Usually in a tuner that's what the muting circuit does, but it is sometimes triggered by noise, and in some tuners if the discriminator is misaligned it will cause muting. Sometimes they also have it mute on turn on to avoid a pop. Sometimes the muting transistors fail in a short condition and mute the output all the time.

I have never encountered that problem so I learned something new today.

I've seen a few times where muting transistors are shorted, in CD players, too. I suspect it happens from ESD when someone has a static charge built up on him and connects the cables. Or it could be caused by connecting the cables to the wrong thing, like an RCA speaker output.

The tuner in question has a variable mute control on the front.
