Completed ZKIT - sounding great
12/01/18 at 17:40:54
 
Built almost a sort of PCB/P2P hybrid. Brazillian cherry wood chassis, aluminum top plate from Landfall, Audyn True Copper signal caps, one input going through a attenuator, the other bypassing volume control. Added the Hazen mod and the 50w resistor. Also have mA meters to make sure the tubes are good. The amp is a tad bit chunkier then I would consider perfect, and definitely doesnít have a professional fit and finish, but for a first-time main amp DIY build, not bad. More importantly, it sounds very, very nice with about 50 hours on it. Thereís a very slight hum that I am assuming is transformer vibration hum - it doesnít sound/act like a ground hum -but it is inaudible once the music starts playing.

At one point I had an issue with bad voltages, but it boiled down to fundamentals - I spent some time cleaning up what must have been some bad solder joints and the voltages went into spec. †Make sure those joints are clean, folks. †;)

One pair of rhodium-plated inputs, one pair of copper-plated.

Thanks, Lon.
Side view. Iíll post a view of the guts later. Right now still ďtestingĒ it, though the test has been going on for about a week now - itís sounding that good that Iím not in a huge hurry to unplug it.
