All had the socket installed, and were cooked 2 output resistor mod. May 24, 6.

That’s one o’ them boxes what makes yer amp sound real dataseet innit? Jun 3, The LM sounds great in there and it is a horrible opamp by todays standards. Sorry to kick over any sacred cows but this is just my opinion based on my experience. There were zillions of the real “JRC” made when it was current.

P Datasheet, PDF – Alldatasheet

It’s a datasheeet relieving to know that some of the opamp chip gurus were willing to let this out of the bag. They had nothing in common.

The reason a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit. I may even run some new tests with more chips, to see if Datasheft can find something better than my beloved TL However, the odds that they’ll hear a difference are very good, and if there’s an audible difference, multiple listeners will have consistent preferences.


On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads.

And is anyone aware that the TS7 has the “correct” chip and output resistor values? If you want “vintage Tube Screamer” then this is the best choice probably. Several electronics suppliers list the JRC May 24, 7.

But even all of these years later, the mystique around the ‘ still amazes me. There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. The differences between the Dztasheet and the are subtle, but there none the less.

The clone had premium caps as well. However, I think the nature of how silicon works vs.

RCP ICs – in stock to buy, photo, pdf datasheet, rfq, obsolete

The in a Tube Screamer datashert have a sound that is good and is what a lot of people find to their liking. Personally, I think it’s the build of the pedal and the sum of all components. Oh, and I should add that it’s unlikely listeners will “get ratasheet chips right” in say, blind testing between vintage JRC and new Fairchild. May 23, 1. We have all gotten used to that noise, so it sounds better.


We have not lost technology over the years, like we have with tubes, we have taken the same technology and made it cleaner in the case of silicon. I replaced the two output resistors with carbon film resistors I had laying around, and I just order a couple of new RCP’s for 25 cents a piece.

May 24, 8. I wish I could say that it sounded noticably better but the TL that I put in the amp did! I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone.

What have y’all overheard at the musician’s watercooler discussions? If you hear a difference then by all means go with what sounds best to you. As far as ‘s in general I will say this.

Definitely better than some datashedt the garbage op amps that were used in the early TS9 reissues. There are millions of these vintage chips out there in old 70’s electronics junk. There’s a tremendous difference between being able to detect a difference and being able to specify the cause of the difference.
