The Univox LM-6 is a compact, low-powered tube amp from Univox's earlier catalog, targeted at students and beginners who wanted British-flavored tube tone in an affordable, portable combo. Its EL84-based output section delivers approximately 6 watts of cathode-biased power with a chimey, compressed character reminiscent of small Vox combos. The simple preamp stage with a single tone control keeps the signal path uncluttered, allowing the EL84's natural harmonic personality to dominate. The LM-6 is appreciated today as an entry-level vintage British-style tube amp with genuine valve character and an easy-to-service circuit.
