M200 Troubadour

The origins of Lectrolab, and its parent – Sound Projects Company – are shrouded in the haze of time.  Perhaps it began as a machine shop, or a cabinet-maker.  Or maybe it sprang into life to take advantage of a radically wacky new idea, the Electric Guitar.

The Troubadour brand is a very early entry in the history of the electric guitar and guitar amplification.

Sound Projects made a matching Troubadour amp to accompany the lap steel and/or the guitar.  This stuff is from the dawn of audio electronics, or at least from the golden age of radio, and I don’t have much knowledge about that.  Maybe some readers can help out with commentary.  The amp pictured below belongs to John McGuire and features:

  • Type 80 tube rectifier, introduced in 1927, a precursor to the 5Y3
  • A Sylvania 6L6GA output tube, introduced in 1942.  This is probably a replacement tube for a 6L6, introduced in 1936.
  • A 6Q7G preamp tube, introduced in 1936.
  • A 6C8G Kenrad with a grid cap, 1937.
  • An 8″ Rola Electrodynamic Reproducer, what we now call a speaker, Model K-8, made in Cleveland, Ohio, output transformer attached.  7500 ohms input, would get along just fine with a 6L6.

The the angled “Troubadour” script logo is much like the later “Lectrolab” logo.

John informs us that this is a model number M200, serial number 1060.
