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. I don’t think I went overboard with the cost on this one. In addition, the JRCD was used in tons of Japanese audio equipment at about the same time, so a junky cheap Japanese stereo or clock radio could have several hidden inside it.
All had the socket installed, and were cooked 2 output resistor mod. But even all of these years later, the mystique around the ‘ still amazes me. The LM sounds great urc4558 there and it is a horrible opamp by todays standards.
No, create an account now. It’s amazing how some of these falsehoods prevail. I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test.
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.

I then went on to check the specs of each ‘good’ chip. As far as ‘s in general I will say this. And I started probing really deep around the time that Analogman started offering their wares, oddly enough.
I wish I could say that it sounded noticably better but the TL that I put in the amp did! By xatasheet reports, these sound as good as the original.
TL my fave The LT was also kinda cool sounding, but not consistently so in the handful of pedals that I tried it in. I’m just wondering where things currently stand. If you hear a difference then by all means go with what sounds best to you.
Your name or email address: Oh, and I should add that it’s unlikely listeners will “get the chips right” in say, blind testing between vintage JRC and new Fairchild. Ben HarmlessJun 4, Back to theI think that people are just applying NOS ideas dtasheet the chips like they do tubes.
And, of course, this is because they all meet the same specifications.
This is where the rec. Log in or Sign up. One of the 9’s was beefed up with better i. May 23, 3.

JRC4558 Dual Op Amp IC
There are other factors like the slew rate that may contribute as well, but to me the input impedance difference is the biggie. So I don’t buy the Holy Grail theory. These 3, in particular, sounded really, really good.
The reason a carbon comp jcr4558 sounds “better” than a film resistor is the additional noise it adds to the circuit. Both have the JRC If you’re doing this to a TS 10, short out the 1K resistor leading to pin 3 of the dual opamp as well.
The thing is, op amps are actually fairly complicated devices internally, and can have widely varying behaviors for slew rate, datssheet, etc, while being “rated” the same in identical conditions. Jun 3,
