Univox U-42 in very good condition, and sounds great too. The amp can do a nice clean sound, but breakup is early and gradual when overdriven. Identification of this amp is via the description at vintageunivox.com, since there are no identifying markings except for the UNIVOX badge which seems to have been the style in 1962-63. Has the expected Jensen 12" speaker and sparkle fabric finish.Tubes installed are 12AX7A 6AV6 6AQ5A 6X4See the closeups of the defect in the piping of the fabric finish.
