I can't remember the model number, but the one I had was 100 watts per channel. I borrowed a pair of (can't remember which ones) Jensen(?) speakers that had 15 inch woofers. I boosted the bass and switched on the loudness. Wow! The record I played was an organ concerto, and the bass was astounding! The windows rattled like never before!
I had it for several years until I moved up to separate components, but I never experienced anything like it since then – even with all that updated equipment.
