I would use Fet opamp (opa2134) at the input and ne5532AP for later have you isolated the op amps as the noise vs any number of other . A 1458 chip is basically a dual 741, and has the same pin connections as the 4558. The nearest equivalent I could get from Mouser (same manufacturer) was a 6amp filter part, so better, but it lacked a screen. A forum devoted to mod, tips and suggestions for upgrading and rehousing your VERY CHEAP commercial stompbox to near boutique excellence. LT1014 Op Amp: Datasheet, Pinout, Equivalent. 33078 quieted the hiss right down. NE5532 would be 'next gen' above the '072. In this example the output signal should be an inverted and amplified signal to five times the size of the input waveform. Easy to fix, but, none of us has ever gone there. The op-amp is also known for its low offset currents, high bandwidth, and low input bias currents due to the JFET based input stage. ha1457w, ha1457w stock, ha1457w price.

Equivalent Input Noise Voltage (VNI):1. 9th December 2009 | Show parent #3. Offering the same warm, open-sounding overdrive as the OSD-9 but with a more pronounced high-frequency response, the OOD-9 is perfect for “livening up” a dark-sounding guitar or amp. Boss - SD-1 Timmy, Landgraff, CJOD, BBOD, BMOD. This eliminates the vast majority of op-amps on the market. The polarity has been inverted. Phase compensation and power supply bypass caps are added. Add to Wish List Add to Compare. The Manual said: CLIP TYPE - Controls the type of clipping circuit used for the distortion generation. When choosing a substitute, you must pay attention to power demands and stability (at least) before trying a substitute. The $3 OPA2134 is supposed to sound much better than the $1 NE5532 and the $10 AD8610 is supposed to sound better still. Am I correct in assuming the D just stands for "Dual Op-Amp"? Nope, that's implicit in the device number. If I'm remembering right the quiescent current on a 4558 is in the 2-4ma per package range and the 5532 is 3-8. It is unity gain stable and comes in a dual op-amp package, the LM 324 is basically the same op-amp in a quad DIP package. You need to do some work yourself. LM158, LM258, LM358, LM2904, LM747. Since there are two junctions between the base and emitter of the Darlington transistor, the equivalent base-emitter voltage is the sum of both base-emitter voltages. If you don't think the desk sounds good, then my advice would be to not buy it. How smooth is the 12V rail? You might want to bypass R3 to 0V with a capacitor and connect it to the +input.
