Описание к видео 1958 Sound Projects Lectrolab R500 (REPAIR, DISCUSSION & DEMO)

Cool little amp! In this video we'll take this vintage 1958 Lectrolab tube combo and open it up, look at a schematic, and repair it. Ultimately, we'll demo it and hear some sick crunch tones using a 1983 Gibson Corvus! This is an interesting circuit because it uses two 12aY7 tubes for the preamp and phase inverter, and push-pull 6V6 output. It's unusual because one would not normall expect this much overdrive from a 12AY7 preamp.

Lectrolab amplifiers were made in Chicago suburb of Cicero, IL throughout the 50s and most of the 60s. The cabinets are generally cheap fiber board, masonite, or other inferior materials, but the circuits are all PTP hand-wired and sound excellent!
