The circuit is problematic: There is quite some gain inside the loop of the TL071. This requires quite some extra capacitors for the compensation to slow it down. With those rather large capacitors the TL071 sees quite some capacitive load and it might thus still oscillate at a high frequency. When you want only the best electronic components, choose 1-Source, a leading Texas Instruments (TI) components supplier. 1-Source Electronic Components is dedicated to providing the very best experience to our customers by offering only the highest quality Texas Instruments (TI) components and superior customer service. The circuit is differential in and out and therefore requires a balanced to unbalanced buffer to give suitable output for the next signal stages of a channel in a mixing desk. This is provided by a high performance op-amp differential gain stage, which can be a TL071 or similar IC of your choice.

Aug 21, 2010 · 5532 is much better than a LF353, which is frankly a shameful device. As op-amps get better (in the sense of faster, with less distortion), they become more fussy about the install environment; 5532 is forgiving and sounds Ok - every recording you own made since about 1980 will have been through dozens of 5534s and 5532s. This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30VDC.

I've read a bit here and elsewhere about opamp replacement. Maybe I'm a bit nutty, but I've been considering replacing the opamps in an old console of mine to improve it's sound quality. It's an old Allen & Heath CMC24 and it's chock full of Tlo72s. For the most part, I've heard it recomended to replace these opamps with AD712s or OPA2604s.

DATASHEET CA3130A and CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors.

Oct 29, 2015 · The "741" has come to often mean a generic op-amp IC (such as μA741, LM301, 558, LM324, TBA221 — or a more modern replacement such as the TL071). The description of the 741 output stage is qualitatively similar for many other designs (that may have quite different input stages), except:

i highly recommend the texas instruments TLE2071 for the channel strips- TLE2072 for dual op amp applications. they're a direct upgrade from the TL071 (which sounds alarmingly bad by comparison) and use about the same amount of current. they're also 3 times faster and have a wider bandwidth. you could get away with swapping a few of the more critical op amps in the master section with some ...
