Substitutes same socket

Parts that fit the same socket: the same function, pin count and pinout. The figures are read off each part's datasheet (this one's from page 22), typical where the sheet gives a typical value, otherwise the maximum. Closest first; the last column says what differs. A different part can change the sound, and a circuit may lean on one particular figure, so read the build document's notes before you swap.

Part	Input	Supply	GBW	Slew	Noise	Iq	Boards
TLE2072		4.5–38 V	10.6 MHz	32 V/µs	17 nV	2.4 mA	1

Fast, low-bias dual drawing about 2.4 mA per amplifier.

Fits the same socket

Part	Input	Supply	GBW	Slew	Noise	Iq	Boards	Differs
OPA2134	JFET	5–36 V	8 MHz	20 V/µs	8 nV	4 mA	108	FET-input audio op-amp without phase inversion; draws about 4 mA per amplifier, so it is hungry on a 9 V battery.
M5216		4–32 V	10 MHz	3 V/µs		2.25 mA	4	much slower. High-current dual (±100 mA load) meant for headphone drivers.
TL072	JFET	4.5–40 V	5.25 MHz	20 V/µs	37 nV	1.4 mA	1338	JFET input; inputs must stay 4 V above the negative rail, and the input range reaches the positive rail.
TL082	JFET	4.5–40 V	5.25 MHz	20 V/µs	37 nV	1.4 mA	72	JFET input; inputs must stay 4 V above the negative rail, and the input range reaches the positive rail.
LF412	JFET	7–36 V	4.5 MHz	21 V/µs	18 nV	0.56 mA	4	FET-input dual with standard pinout per the drawing (the 2026 pin table misprints pins 4 to 8).
UPC4570	bipolar	8–32 V	15 MHz	7 V/µs		2.5 mA	5	much slower. Low-noise, wideband audio dual; needs at least ±4 V (8 V) supply.
OPA1678	RR out	4.5–36 V	16 MHz	9 V/µs	4.5 nV	2 mA	6	rail-to-rail output. Surface-mount only (SOIC-8 and smaller), so a DIP socket needs an adapter; standard dual pinout.
M5218		4–32 V	7 MHz	3 V/µs		1.5 mA	21	much slower. Low-noise audio dual the maker calls close to the 4558 and 4559, with ±50 mA load current.
NJM4565D	bipolar	8–36 V	10 MHz	4 V/µs		2.25 mA	2	much slower. Drives 20 V peak-to-peak into 400 Ω; the DIP8 (NJM4565D) is listed as discontinued.
4580	bipolar	4–36 V	15 MHz	5 V/µs		3 mA	103	much slower. Low-noise, high-output-current audio dual from ±2 V; the DIP8 (NJM4580D) is listed as discontinued.
