Im selling my gently used Little Bear vacuum tube phono RIAA preamp. It is in great working condition and sounds wonderful! Ive only used it a few times so I cant justify keeping it, so thats why Im selling it. It comes with an AC power cord. I originally bought this used on eBay about 10 years ago from a dependable seller. He had built a little grounded screen that was placed over one of the tubes to help shield it. You can see it in some of the pictures. The tubes that are onboard are three 6N2s and one 6Z4. But the board will also accommodate 12AX7s instead of the 6N2s. So, depending on the type of tube you are using, you must flip an onboard switch near that tube. Its fairly simple and straightforward. There is even a switch for high and low level output which is very convenient. Please view all the pictures. Please note that one of the bottom corners of the acrylic is chipped (It was already there when I purchased it) but it does not affect the functionality of the preamp. This Phono preamp will be packaged securely to survive shipping. All sales are final, no returns. Thank you for looking.

The Little Bear T7 Vacuum Tube CD/MM phono RIAA preamplifier is a highly sought-after audio device for sound enthusiasts. With its unique tube amplifier technology, it delivers a warm and rich sound that will enhance your listening experience. This preamplifier is designed for use with CD players, turntables, and other audio sources, making it a versatile addition to any audio setup. The Little Bear T7 features a sleek design and is built to last. Its durable construction, combined with its exceptional sound quality, makes it a top choice for discerning audiophiles. Whether you're a vinyl collector or a CD enthusiast, this preamplifier is sure to impress. Works perfect

Im selling my used Little Bear vacuum tube phono RIAA preamp. It is in great working condition. Ive only used it several times. It comes with an AC power cord. I originally bought this used on eBay about 10 years ago from a dependable seller. He had built a little grounded screen that was placed over one of the tubes to help shield it. You can see it in some of the pictures. The tubes that are onboard are three 6N2s and one 6Z4. But the board will also accommodate 12AX7s instead of the 6N2s. So, depending on the type of tube you are using, you must flip an onboard switch near that tube. Its fairly simple and straightforward. Please view all the pictures. Please note that one of the bottom corners of the acrylic is chipped but it does not affect the functionality of the preamp. This Phono preamp will be packaged securely to survive shipping. All sales are final, no returns. Thank you for looking.
