JRC Datasheet PDF – Dual Operational Amplifier Clever marketing can take advantage of this to sell a ten cent amp for ten bucks.
It’s a little relieving to know that some of the opamp chip gurus were willing to let this out of the bag. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different. I sent Analogman my TS-9 several years ago and dqtasheet him replace the chip and beef up some weak spots with no other mods and it came back as he described: I started researching TS’s quite a long time ago. 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. Some circuits sound better with inferior spec’ed chips. I think the high end stereo guys, in particular, have been suseptable to this sort of pseudo-scientific clap-trap. Put a TL in there and be prepared for an overly bright and brittle sound. 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 daatsheet another clone of the same circuit that I paid significantly less for and it shows. I liked the 3 listed above enough to ‘splurge’ and order about 15 of each. JRC Datasheet pdf – = NJM / Dual Operational Amplifier – New Japan Radio The thing is, op amps are actually fairly complicated devices internally, and can have widely varying behaviors for slew rate, noise, etc, while being “rated” the same in identical conditions. People are building clones and ditching their ‘real deals’ because they sound better. There are probably 3 that most guitarists would agree sound ‘bad. When you order these, you get parts that are labeled “JRC”. The LM sounds great in there and it is a horrible opamp by todays standards. Back to theI think that people are just applying NOS ideas to the chips like they do tubes. I then dataaheet on to check the specs of each ‘good’ chip.
I may even run some new tests with more chips, to see if I can find something better than my beloved TL I replaced the two output resistors with rjc film resistors I had laying around, and I just order a couple of new RCP’s for 25 cents a piece.
