| Ref | Value | Normalized | Type | Notes |
|---|---|---|---|---|
| Resistors 4 | ||||
| ×5 | 10k | 10k | one in the top feedback branch, two around the top pot, two as the bias divider; read from the schematic by eye | |
| ×2 | 3k3 | 3.3k | read from the schematic by eye | |
| ×2 | 1k8 | 1.8k | read from the schematic by eye | |
| ×1 | 270R | 270 | in series with the 1n to the inverting input; read from the schematic by eye | |
| Capacitors 7 | ||||
| ×1 | 1uF | 1u | input coupling; read from the schematic by eye | |
| ×1 | 47n | 47n | across the top 100k pot; read from the schematic by eye | |
| ×1 | 22n | 22n | middle pot wiper to inverting input; read from the schematic by eye | |
| ×2 | 4n7 | 4.7n | one across the middle pot, one from the 470k pot wiper; read from the schematic by eye | |
| ×1 | 1n | 1n | read from the schematic by eye | |
| ×1 | 100u | 100u | supply filter, electrolytic; read from the schematic by eye | |
| ×1 | 33u | 33u | bias filter, electrolytic; read from the schematic by eye | |

| ×1 | LF351 | LF351 | single op amp; read from the schematic by eye | |
| Potentiometers 2 | ||||
| ×2 | 100k | 100k | Potentiometer | unlabeled; top one (47n across it) acts as bass, middle one (4n7 across it, 22n to wiper) as mid; read from the schematic by eye |
| ×1 | 470k | 470k | Potentiometer | unlabeled; bottom pot with 4n7 from wiper, acts as treble; read from the schematic by eye |
