And this month, I sing the praises of another obscure and beautiful amplifier, in this case a 1966 Lectrolab S 400. I’ve seen a few Lectrolabs over the years and they are all pretty cool amps. The 400 series seem to be (and this is based only on observation and scattered information. No one seems to know very much about these) all single-ended small amps with a single EL84 for output and one or two eight inch speakers. The 600 series are more in the 15-20 watt range with either two 6V6’s or two EL84’s (driving a twelve inch speaker), depending on the year. And the 800 series, which I’ve never seen in person, I haven’t been able to find much about, other than that they seem like later versions of the 600’s. The 900 series are El84-equiped heads (very rare).
