    Preamp Buzz/Hum

    Well in that case the caps I put into it should do you just fine.

    It'll go out to you tomorrow or Tuesday. Shipings my treat so just toss a couple of cans of food into your local food bank collection box as recompensense.

    thebes,

    I'll be happy to do that, but you deserve something for your trouble. What can I do for you?

    thebes,

    This preamp is going in a warehouse environment where the sound is pretty bad anyway. I don't want to sink a lot of money into this thing, because of it's age. Let's just do what is absolutely necessary.

    Thanks again,

    Tony

    Well geez Tony if you are just going to toss it back into the closet send it to me and I'll see if I can fix it. I've still got the old caps here so I can test and substitute, and see if I can get it up and running.

    I might just take you up on that. I'd be more than happy to pay for parts and labor. I just need someone who knows something about this sort of thing.

    Thanks,

    Tony

    No doubt that can be true. I wonder if this was ever used SUCCESSFULLY with the T-amp in the past? I bet not. These amps have some peculiar grounding I found out.

    It might be cheaper (like 50 bucks) to just get another one:

    Or, try using it with a different amp - - just to see.

    I tried it with other amps, as well... same problem. I thought about buying another 101, but I could end up with 2 preamps with the same or similar problems... you never know what you'll get.

    Thanks,

    Yes, the buzz does increase when you turn up the volume on the amp. I can only run the Super T at about 1/4 volume before it becomes "noisy". On amps without a volume (amp running wide open), the buzz is unbearable. No other symptoms.

    Thanks,

    I guess it's more of a buzz. It sounds like it's coming mainly from the mids to me. This thing has been in storage for awhile now. I've tried this preamp at 3 different locations... same buzz. Leaving it on for awhile or turning it off doesn't seem to affect it in any way. I'm stumpted.

    Thanks,

    I'm working on a Hafler 101 preamp that has a buzz/hum through both channels. It happens with any amplifer and it's variable with the volume on the amplifer. In other words, if I keep the volume on the amp (Super T) low, it's not as noticable as when the volume is turned up on the amp to a higher level. I've grounded the unit. Anyone out there have any ideas as to where to start. Anyone out there work on these things?

    Thanks,

    Tony
