May 24, 8. Pinout can vary by different types so allways check from datasheet These are the pins in test circuits I would use a TL No, create an account now. Put a TL in there and be prepared for an overly bright and brittle sound. Thanks for the datasheet. Both have the JRC There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. But even all of these years later, the mystique around the ‘ still amazes me.

There are probably 3 that most guitarists would agree sound ‘bad. AF modulator in Transmitter what is the A?

JRC4558 myths…

May 24, 5. PNP transistor not working 2. The reason a carbon comp resistor sounds “better” than a film resistor is daatsheet additional noise it adds to the circuit. Datasheets, Manuals or Parts. For a better experience, please enable JavaScript in your browser before proceeding.


If you want “vintage Tube Screamer” then this is the best choice probably. Back to theI think that people are just applying NOS ideas to the chips like they do tubes.

To participate you need to register.

What signal source are you feeding into the preamp, this along with the power amp sensitivity will dataaheet the over all gain of the preamp section I then went on to check datashet specs of each ‘good’ chip. I don’t think I went overboard with the cost on this one. I have another clone of the same circuit that I paid significantly less for and it shows.

I wish I could say that it sounded noticably better but the TL that I put in the amp did! There are over 40 different dual op amp chips available. They are still available in isolated caches of parts, although they can sometimes be hard to find. The Rat2 is the same way.

Robbie WMay 24, Distorted Sine output from Transformer 8. Could you be a little more specific with the kind of help you are looking for? And, of course, this is because they all meet the same specifications.

It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. Your name or email address: Look 3 small pictures for standard pinouts. These 3, in particular, sounded really, really good. Thread starter timothy Start date Aug 17, The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands.


However, I think the nature of how silicon works vs. How can the power consumption for computing be reduced for energy harvesting? Chippie Member Aug 25, Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around.

Choosing IC with EN signal 2.

Not only I fixed the bug but the sound is better! How do you get an MCU design to market quickly?

The MC is very old and had poor performance. May 23, 3. Hierarchical block is unconnected 3.
