Are the specs of the Bipolar Placid (15v) comparable with the Paul Hynes shunt regulators? (see below)
===>
Error amplifiers in regulators above 12 volts have a slew rate over 2,000 volts per microsecond and a minimum bandwidth of 150 MHz. Error amplifiers in shunt regulators up to 12 volts have a slew rate of 5,000 volts per microsecond and a bandwidth of 1 GHz. Settling time in all error amplifiers is < 10 nanoseconds and wideband noise spec 2 nanovolts root HZ. Typical output impedance from DC to 200 KHz for the Shunt regulator is less than 0.001 ohm and the series regulator is less than 0.005 ohm. Regulator dropout voltage is 1.5v for shunt and 3v for series.

Thanks,
Rob

I would very much like to know the answer to this too, and the current ratings of Paul's regs too. People seem to happily use both in the Buff 1 and 2 however.

The *specs* you copied are pretty loose and I don't see any evidence presented to back it up, so I would need to verify them for myself before I put much faith in them. Not that I have any reason to doubt them, but I have not seen anything to make me believe them either.
In any case I try not to make astounding claims about the Placid simply because I don't have the testing gear to prove my statements. What it comes down to for me is that it is proven and people seems to love it. And as a benefit you can see exactly how placid works and it is public. We also don't charge a premium for something that is not expensive to build.

Buffalo 24, 32S and II came out quite a bit of time before the Tridents and it is therefore not strange that the use of Paul Hynes mini regulators is very diffuse among Buffalo tweakers. Certainly these regulators are proven and have a tremendous reputation.
My guess is that both the TPA and the PH regulators are very good and we all have the choice to get what we want (pending availability and delivery times).
Actually there are quite a few suppliers of this type of regulators.
Is the Trident circuit public?
Cheers,
Nic

No, the Trident is not public, but I thought we were talking about the Placid BP. :)

Since we are already off topic, when are Tridents likely to become available again?
