**Notes**
|
|
||||||
- **Output cap must be big (~470µF, ≥16V).** Into 4 Ω, 47µF high-passes at ~850 Hz →
|
|
||||||
kills the bass (brown noise is all lows). Fat electrolytic, **+ → pin 5**.
|
|
||||||
- **Gain ×20** (pins 1 & 8 open). Back off with VOL to avoid clipping. A 10µF between
|
|
||||||
pins 1 & 8 gives ×200 — usually not needed.
|
|
||||||
- **On +12 V the LM386 runs warm into 4 Ω** (LM386N-1 max = 12 V). OK for testing;
|
|
||||||
for cooler running feed it from ~9 V.

## Build & test order

Build one stage at a time — verify before adding the next.
|
1. **VREF** — confirm ~6.0 V.
|
||||||
|
2. **Noise (R1, Q1)** — scope Q1 node → hiss (~mV). None? swap 2N3904 or raise supply to 12–15 V.
|
||||||
1. **VREF** — R2/R3/Cref up. Confirm ~6.0 V.
|
3. **Amp (U1B)** — scope AMP → loud hiss (~volts).
|
||||||
2. **Noise (R1 + Q1)** — scope Q1 node → hiss (~mV). No noise? swap the 2N3904 or nudge supply to 12–15 V.
|
4. **Driver (Q3)** — feed AMP through Cc. Speaker hisses. Q3 warm, not hot; too hot → raise Re.
|
||||||
3. **Amp (U1A)** — scope AMP → loud hiss (~volts).
|
|
||||||
4. **Integrator (U1B)** — BROWN sounds darker/deeper than AMP. That's brown noise.
|
|
||||||
5. **LFO (U2A)** — scope LFO_CV → slow ramp, ~20 s.
|
|
||||||
6. **VCA + buffer (Q2, U2B)** — full chain: noise swells and fades on the LFO cycle.
