- Worth noticing
- A service-log entry records a 1976 Pioneer SX-1250, 0.04% measured THD, and a 48-hour soak test in progress.
Field notes
The stated service range covers receivers, integrated amplifiers, turntables, and tape decks from 1965 to 1990. A bench card names a Pioneer SX-1250 and reports its idle-current setting alongside a 48-hour soak test. The articles also describe a repeatable plugin check: send a sine sweep through a saturator, then inspect the output with a scope and spectrum analyzer.
