Elekit TU-8500 Pre-amplifier. Employing the finest components this pre-amplifier features Takman 1% and .1% resistors Mundorf Phono Caps, AudioCap line stage capacitors, NOS Sylvania JAN 6189W tubes, and Burr Brown OPA2227P opamps in the phono stage. The preamp is in good condition, sounds great and functions as expected except for a slight 2ish dB imbalance between the left and right channel. I'm not sure if that is a mismatch between the tubes or the stages of the potentiometer but it would be easy to fix by adding a resistor after the pot. Kit price without upgrades is $585. I am asking $450 plus the actual cost of shipping. Box is 12x12x7" and 10 lbs.
