    I gave Analog Engineering Associates my Sansui 1000a

    I've had a Sansui 1000a for some time that I've been afraid to turn on because of old caps. I've decided to send it to them for a cleaning and recap. They said that it'd be a three month turn around on the project. I can't wait to actually get it back and put it through its paces (without...

    Afternoon all, Since I am surrounded by experienced audio lovers, I had a question I hoped you could help me with. As someone who's listened avidly to music for 40+ years, and who has gotten more serious about gear over the last few years, my question is if anyone else experiences tinnitus...

    Adding a Pre Out to a Luxman R-1050

    Morning All, I currently own a Luxman R-1050 and truly enjoy the sound from it. However, I have also been presented with an opportunity to get my hands on a Jolida JD-302BRC, which although an integrated, has no phono input, and overall limited inputs. So my thoughts were to use my R-1050 as...

    Request: Help Identify Zenith Console

    Could anyone here help me identify this Stereo Console? I am picking her up later this evening (free post on local CL), but don’t know a thing about Zenith consoles. Any information would be greatly appreciated. Seller said that he thinks it hasn't been used in 40 years. Yikes!

    Fisher 500c Tubes to Improve Sound

    Hi Fisher people, I recently acquired a really nice Fisher 500C. It's the first tube receiver I've owned. It's been largely recapped, and with new selenium rectifier, etc. Basically, it's been upgraded and tuned up. But I have to say, the sound I find still kind of blah- not that distinctive...

    I received a call from a friend in Ottawa, Canada, who asked me what I thought about the subject line. He has a small collection of audio gear, and is thinking about swapping his Marantz 2245 in excellent condition, for an Eico ST-40, which looks to be in good shape. He likes both SS and hollow...

    Faulty tube, which one to replace, there are so many?

    I'm currently using the Fisher 500c as a headphone amplifier & all of a sudden the bass got real distorted & noisy. I think one of the power tubes might be dying died. I'm pretty sure of it, as one of them flashed blue before I started getting the noisy bass. I plan to replace all 4 power tubes...
