JRC Internal Circuit. The Active Current Supply it is a utility stage which provides a constant flow of current to the different blocks. A stable current source is important in order to improve linearity and noise rejection. With zero VGS the transistor enters in saturation region allowing a large current to flow through the JFET, so the current will increase.

Samular The TL has a lot higher input impedance extremely higher actually. There are other factors like the slew rate that may datassheet as well, but to me the input impedance difference is the biggie.
Log in or Sign up. If you hear a difference then by all means go with what sounds best to you. Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful. This is where the rec.
And, of course, this is because they all meet the same specifications. TL my fave The LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in. Clever marketing can take advantage of this to sell a ten cent amp for ten bucks.
The old pedal was not superior to the new one in any way, in fact, it was inferior in ways. They were consistently good. The LM sounds great in there and it is a horrible opamp by todays standards. I wish I could say that it sounded noticably better but the TL that I put in the amp did!
The reason that I even started this thread was to try to get a feel on where the whole TS mojo thing stands. The TL drives things harder and it is tighter and crisper. Your name or email address: There dataasheet over 40 different dual op amp chips available. Sorry to kick over any sacred cows but this is just my opinion based on my experience. No, create an account now. May 24, 6. I have another clone of the same circuit that I paid significantly less for and it shows. Datassheet feel this is the primary reason for the audible differences.
On the other hand, I also think we all at least I have personally tried some of the products on the idea of datasueet I can afford it, what can it hurt? I know I read something recently about the that even when the TS was in original production, there was daatsheet single vendor. May 23, 3. Put a TL in there and be prepared for an overly bright and brittle sound.
