[QUOTE="Douglas R. Allen, post: 84576, member: 71"] Re: Original 01v preamp issues? Posting the fix should anyone run into something like this in the future. Pretty simple as it turned out. I called the person who has it for sale and asked how they used it. He said in his studio and it was always fed with the 1/4 inch TRS jacks..... So I got an XLR to 1/4 TRS adaptor and all the channels work fine in the 1/4 inch line inputs! Seems the 1/4 inch inputs are switching jacks. They shut off the Xlr inputs so both won't be used at the same time. They needed some cleaning being used and the switching pins not touching for so long! So I dug out the Deoxit to spray the 1/4 inch inputs and a jack to worked it in and out. All XLR inputs work fine now so I'm guessing the switching jacks were open for so long that crud built up where the pins should make contact when the jack is pulled out. Everything works great on it now. Douglas R. Allen [/QUOTE]
