And now, the Regulator-Chip JLH Amp.

Wow. I didn't notice yesterday how old this thread is.

Here it is:

Is that a Tripath Lm 317?

It is a Thomson one

I came across some pairs of very high quality with identical offset in the mv range LM317/337 from Motorola and I'm thinking of trying one of your amps.Which of them are you recommending for best results?

After the Regulator Chip Amp and the Chtringlunator, it is time to translate the JLH topology into voltage regulators (I hope JLH won't be turning in his grave).

The task is pretty straightforward, and the results are excellent.
And since the circuit operates in class A, it doesn't have slew-rate issues.

In practice, R2 and R9 can be halved: the spice model I have for the LM317 reaches its current limit at only 850mA, about half the actual device. This will make the amplifier able to drive a 4 ohm load.

Pics will follow.

Clever 👍🙂🙂

You could try this one (JLH): being class A + PP, it combines a decent output power with a superior quality
