    MIne sounded pretty good. Swapped out the stock tubes for a 'matched' pair of JAN GE 5654s and it served its purpose well. I've since upgrade to the Yaqin MS-23B but I still use the Little Bear upstairs on the Tech 12.

    It's AC.

    Jeff, your $30 FX is DC 12V and with a $30 Pyramid regulated power supply it is stupid good.

    You should try a pair of 5751's, black plates only,in your Yaqin, they are known as an audiophile's 12AX7 because they offer only 70% of the gain of a 12AX7, which means lower noise and distortion, they are especially good in phono sections.

    I will look into that. I'm currently using a matched set of 1958 RCA Slanted D-getter 12AX7's and found them to be nice and buttery with plenty of gain.

    I have this, it's a terrible phono, very low output, and poor SQ. There's a switch to just use it as a tube pre, it works ok in that way.

    What do you mean? I bought it on one of the aliexpress sales for like $40 shipped. It works, and does what it says it does, just not very well. I did try tube rolling, since I had a bunch already.(GE Jan5654, voshklods, a few others). As a phono, it's a terrible device, extremely low output volume, and what you get sounds broken. I have 3 other cheap phonos that are worlds beyond this device (rolls vp, realistic 42-2101a, ps audio phono II). As a tube buffer pre, it works fine, but there are devices that are cheaper that do exactly this.

    The 1 star reviews are scathing and consistent. This isn't a well-designed unit like the FX Audio pre in the other thread. Internals look like the typical cheap Chinese pres. It's luck of the draw with these - maybe it'll work, maybe it won't. Maybe it'll work for a while, maybe it won't.
