Vintage JBL SA660 // Integrated Amplifier / Restored / Original Box 77705

SOLD , now part of a Private Collection
Quite possibly one of the most design-forward components JBL ever released is also one of the most revolutionary. While solid-state was still in its infancy, the engineers at JBL developed an output stage that remains, to this day, the go-to architecture for high performance designs. Around the time of its release, the lead engineer wrote an article for Electronics World which details this clever output stage, nicknamed the "T" circuit (see 'Downloads' section). It was highly regarded in its day for its liquid tube-like sound, and is today prized by collectors for both its appearance and outstanding listening experience. This piece was lovingly cared for, yet after over 50 years, you'd expect a few blemishes. While no exception, this piece is still an absolute stunner.
