[McIntosh MC240 × ALTEC 612C] Rainy Night Tube Amp × 604 Coaxial × LINN LP12 5H Late Night JAZZ BGM

Rain on the glass, glow in the tubes. Outside, the neon hums through a wet city night; inside, four GE 6L6GC valves of a 1960 McIntosh MC240 warm the room while an ALTEC 604 coaxial speaks with one voice. This is the rainy-night listening room. Tonight's reference: the McIntosh MC240 (USA, 1960) — the velvet-transformer stereo tube amplifier — partnered with the ALTEC LANSING 612C studio monitors (1975) and vinyl spun on the LINN LP12 with the SME 3009R tonearm. American iron, American theater sound, Scottish precision — one rainy night. Five hours of warm, tube-lit, audiophile vintage JAZZ BGM. ※ The rain lives in the visuals only — the audio is pure music, no rain SFX, mastered for quality listening. ▼ Subscribe for more late-night BGM    / @bar-time-jazz-f3j   🎧 Also on Spotify / Apple Music / Amazon Music — search "FM Jazz Bar" 🛠️ Tonight's Reference System ───────── 【POWER AMPLIFIER】 McIntosh MC240 (USA, 1960) The stereo tube amp many collectors keep beside the MC275 — and some prefer. 40W+40W from four GE 6L6GC output tubes (with 12AX7×3, 12AU7×2, 12BH7×2), McIntosh's patented Unity Coupled output transformers, frequency response 16Hz–40kHz, 25kg of American iron. Its signature: a lush, liquid midrange — fresher and sweeter than its bigger brother — that turns saxophone breath and piano overtones into candlelight. Sixty years on, still the heart of countless reference systems. 【PREAMP DUTY】 McIntosh blue-meter integrated A later-generation McIntosh with the signature glass front and blue watt meters handles source switching and volume — the blue glow answering the amber of the valves above it. 【SPEAKERS】 ALTEC LANSING 612C Monitor (USA, 1975) The studio-monitor refinement of the storied 612 cabinet — list ¥295,000 per unit (1976). Inside: the legendary ALTEC 604 38cm duplex coaxial, the driver that monitored half the golden recordings of the 20th century, with the high-frequency horn firing from the very center of the woofer cone for true point-source coherence. The 612C's precision-tuned bass-reflex enclosure extends the low end. The unit evolved across its life — 604-8G → 604-8H (1979) → 604-8KS (1981). Voices and horns lock into focus the way only a 604 can. 【TURNTABLE】 LINN LP12 + SME 3009R (Scotland / UK) The Sondek LP12 — Glasgow's belt-drive icon, in production since 1972 and still the analog reference for many. Here an early LP12 carries the SME 3009R: static-balance, short arm, tracking 0–5g, happy from featherweight MMs to 22g SPU-class cartridges. Dense information, rich tone colors, and the unhurried weight that only vinyl delivers. 🎵 Music Style Slow tempo · upright bass · saxophone · piano · dark · deep · warm · instrumental Tube warmth through a point-source coaxial — body, air, and rock-stable imaging. NOT a busy daytime cafe BGM. Designed for after-hours stillness, rainy-night reading, slow drinks, or restful sleep. 🎯 Recommended for Audiophiles & tube lovers (McIntosh / ALTEC / LINN) 604 coaxial & studio-monitor enthusiasts Rainy-night work, reading, writing, vinyl listening Whisky & wine evenings, sleep aid, deep relaxation 🎼 Tracklist (5 hours · 40 tracks · Rainy-Night Hi-Fi JAZZ Best Mix) ▼ Set 1 00:00:00 Rain on the Glass 00:02:14 MC240 Glow 00:04:20 Coaxial Velvet 00:06:26 Blue Meter Drizzle 00:08:43 6L6 Warmth 00:11:25 Neon Through Raindrops 00:14:33 LP12 Slow Spin 00:16:35 Duplex Bloom 00:18:51 Tube Heat Shelter 00:21:09 Wet Street Serenade 00:23:30 Umbrella Bossa 00:26:05 604 Whisper 00:28:04 Idle Hours 00:30:11 Velvet Transformer 00:32:50 Night Bus Window 00:34:57 Amber Lamp Ballad 00:37:10 SME Tracking Lightly 00:39:46 Rainy Kissa Mood 00:42:22 Crosstown Drizzle 00:44:34 Altec Air 00:46:58 Midnight Wiper Rhythm 00:49:09 Glasgow Belt Drive 00:51:35 Puddle Reflections 00:54:49 Late Shift Sax 00:56:39 Warm Cathode Night 00:58:47 Raincoat Standards 01:00:59 Monitor Green 01:02:52 Slow Jazz Downpour 01:05:18 Tube Bias Lullaby 01:07:54 City Mist Piano 01:10:35 After the Rain 01:13:06 Coaxial Dreams 01:15:11 McIntosh Blues 01:17:13 Drizzle & Bourbon 01:19:11 Window Seat Ballad 01:21:25 Last Train in the Rain 01:23:38 Valve Glow Vesper 01:26:04 Quiet Storm Lounge 01:28:15 Umber Evening 01:30:26 The Rainy Hour ▼ Set 2 (Loop) 01:32:47 ▼ Set 3 (Loop) 03:05:34 Tracks loop seamlessly through the full 5 hours. 🎯 Related: Jazz Cafe · McIntosh Tube Jazz · ALTEC Coaxial Jazz · LINN Vinyl Jazz · Rainy Night Jazz 📜 About this Channel FM Jazz Bar — vintage & modern audio jazz BGM.
