A Bulgarian Builds A Spencer Amp
Reader M. Nyssen was so impressed by Rick Spencer's article "A Great First Amplifier Project" (12/01 aX) that he built a half-dozen variations on the Spencer design, and proceeded to sell them at an audio meet in Bulgaria. He sent the editor a handful of photos from which we selected three.

DC.

PHOTO 1: Two channel 15W/channel, ultralinear with a separate power supply. The chassis is U-shaped aluminum with wood end pieces held together with internally threaded aluminum rods.
