 I just had the opportunity to review the most recent release, Live , from Zac Harmon & The Drive and it's super! Opening with soulful, NTRO , Nate Robinson on bass and Gino Iglehart on drums set a solid foundation, with Corey Lacy building on keys and lush guitar work by Zac Harmon and Kingston Livingston really setting the bar. Terrific opener. Blue Pill Thrill has super movement and soulful vocals by Harmon. Lacy on keys works the rhythm with Robinson and Iglehart and Livingston and and Harmon play stinging riffs on guitar really giving this track some kick. Deep blues track, Feet Back On The Ground features Albert King like stinging riffs and super soulful vocals by Harmon. Keeping the music floor low allows Harmon plenty of space to go dynamically from soft to wow quickly adding real emotion to the track. Excellent! Boogie Down is a strong jam with a firm piano base by Lacy giving Harmon plenty of headroom for vocal corralling. Lacy lays in some real tasty keyboar...

Tech Talk - Lectrolab R200 (1953)

* 2 Inputs, one Volume, one Tone control. * The filaments in these tubes are powered by 25 to 50 volts AC. This is in contrast to almost all modern amps which use 6.3 volts. * 50L6 is the power amp tube, capable of 4 to 8 watts depending on the circuit. Without knowing the transformer specs, or measuring an example, we can’t state with certainty what the R200 output is. * 35Z5 is the rectifier. These have been used in other designs with no power transformer, which can lead to the chassis being “hot” (117VAC) whether the amp is on or off. I believe the term “widow-maker” refers to that design feature. The R200 and R200b schematics both show a power transformer that would isolate the line voltage from everything but the tube filaments. One side of the AC line is tied to ground through a capacitor, creating a “signal ground”. * This does not make them safe! The schematic does not show how the chassis is grounded.
