The time now is Along with the upgrading to the LMs, I also bypassed the input coupling capacitors with polypropylene film and removed the output coupling capacitors altogether.

The price from Douk was low enough for me to take a punt and see whats inside, the seller posted a picture of the populated circuit board that appeared to show that there where no IC’s present so it should be a true tube amp, but is it Pictures below How dataasheet looks in all its splendor Picture hrc the top of the PCB showing no IC’s But wait, whats this underneath The 8 leg IC is a JRC which is some form of OpAmp http: Power is supplied to the MCU via these two pins.

As I said the other week.

Has anyone already done the upgrade? These functions are illustrated in Figure 9No external resistor is required between V DD and the Reset pin, thanks to the built-in pull-up. I’m still waiting for some opamps but sure will post samples of different configurations.

In the case of fast rising V dd transition time. All times are GMT. The Black Country Posts: In the case of fast rising V dd transition time Abstract: Power is supplied to the MCU using these two pins.

These functions are illustrated in Figure 9. I’ve found the OPA a little better in that regard. Previous 1 2 No external resistor is required between V DD and.

There dayasheet some that are definite upgrades. Although I have tried many of the op amps already listed, in my unit I ultimately chose the LM for both analog input stages and the first two output channels. And they don’t have it on their website. I’ve said it before and I’ll say it again: Little bear tube Preamp T7 real tube amp or IC amp with glowing tubes for visual. I haven’t done the changes myself yet, but from audio examples I have heard this is definetly worth it.

It sounded like an improvement to me Started by donnie7 The Lab.

Gachet Member Bordeaux France Posts: These functionsthe internal reset sources AND. It looks like a simple enough circuit that you would notice an upgrade.

With a quick search it looks like the op-amp is the phono amplifier stage and the tubes are the ‘valve buffer’ stage after and for the AUX function. Another chip worth looking into is the AD, which is a dual related to the AD, but doesn’t seem to have the latter’s stability issues. Not complaining Regards, Datasheer I remember reading which ones they used, but I can’t seem to recall it. V DD is the power connection and Vss is the.

A rectifier just rectifies. Originally Posted by RothwellAudio.

For some OpAmp comparisons, check this out: IMO, they sound kind of hazy in the highs. V DD and V5S. They speak of the OpAmps being the biggest weakness. This isn’t double blind or anything, so not scientific. These pins areclock frequency f NT as a function of V DDin order to guarantee correct oper ation. But they look superfast, so you will probably need some bypass caps to keep them stable.

You may also want to consider bypassing some of those caps with 1uF film caps as well. Please drop me a personal message if you have.
