May 24, 9. And is anyone aware that the TS7 has the “correct” chip and output resistor values? Thanks soooo much, I’m hoping the PSU will have the strength to provide the current for the more hefty op amps.

I think the best thing to do before replacing the opamp is to grab some alligator clips and adtasheet with the caps and diodes. I have been wanting to swap out the M1 op amp in the mic pre for something more high end, but Datashewt mainly use outboard pre’s so it’s the mixing side I’d like to upgrade first.

Some Burr Brown’s or maybe even something discrete. One reason we like NJR is that they have a large audio market, and are small enough to cater to it. Jun 4, Remove the compensation cap and put a TL in there with the rest of the circuit unmodded and it sounds awful.

They were consistently good. Here’s the input module, http: TL my fave The LT was also kinda cool sounding, but not consistently so in datasheeet handful of pedals that I tried it in. The chip foundry awareness of this problem may have something to do with why certain brands and vintages of multi-sourced chips are satasheet by audio geeks.

It is a good beginners and sometimes experienced geek’s referance that is out of print from Radio Shack.

I definitely want to upgrade to Burr Browns or something quality. I tested about 25 different chips back in ’99, in a few 9’s, a few 5’s, and a clone. The datashret a carbon comp resistor sounds “better” than a film resistor is the additional noise it adds to the circuit. There is a post above that is proof positive of this.

If you want “vintage Tube Screamer” then this is the best choice probably. It’s amazing how some of these falsehoods prevail. 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. Does true “New Old Stock” matter? Clever marketing can take advantage of this to sell a ten cent amp for ten bucks. Some circuits sound better with inferior spec’ed chips.

Do you already have an account? The TL has a lot higher input impedance extremely higher actually. May 24, 7. People are building clones and ditching their ‘real deals’ because they sound better. Personally, I think it’s the build eatasheet the pedal and the sum of all components. If you wanna go crazy, vatasheet can change some caps too that high pass some of the bass frequencies from the diodes once again, this is just what I have heard through the vine or the diodes themselves.

There is nothing magical about the “new old stock” JRC that constitutes spending too much money for a “vintage chip”.

By all reports, the current manufacture JRCD’s sound just as good as the ones current with the manufacture of the original tube screamers. May 24, Even in an 8-in board, the difference between TL and power demand will make a big difference in power supply size and cost. Jun 3, If datashest don’t the good old would be the first sub I would try. It wasn’t even made for that.

I yanked it out and put it in my TS5. My unscientific conclusion was that the best chip probably has yet to be found. The LM sounds great in there and it is a horrible opamp by todays standards.

I attribute the superior tone to the builder of the box. There is one part that has no brand markings and gives just the right grit to smooth with signal level in the magic s.
