Black Quicksilver Full Function tube preamplifier in very good condition, conservatively rated. This is the more desirable version using the two 6x4 rectifier tubes. Has a phenomenal phono stage as well. Currently has a set of premium tubes inside -- I believe a NOS American black-plate 5814 in the line stage and a Telefunken smooth plate 12AX7 in the phono stage. Will include multiple pairs of spare 6x4 tubes and possibly some other tubes if asking price is met (will ship separately at your expense).
