Tridents up and running!

However, I can "only" get 475mA @ 5.45VDC out of the Placid at max trottle, thus shunting approx 25mA.
Is this ok? How to get it to deliver more?
Nedless to say I want MAX audio performance, perhaps order LCDPS, or is that a complete waste of money?

Cheers,
Tom Think

Not quite enough.

The answer could be here:

Remember, Russ' answer, reducing R6, refers to Placid ver. 2.0.

The same resistor in version 2.0.1 is named R5.

I got Placid 2.0.1.
So changing R5 from 22R1 down to 5R or 10R should do the trick?
Which value is better?
Then (before the change) reduce current down to say 250mA @ 5V before turning off?
Do replacement, and it should be ready to fine adjust with more max current and shunting 50-60mA?
Btw, I do have good ventilation...

For Version 2.0.1 try R5 4.7R or 5R. :) But even a short is ok.

Thanks for the tips avr300 and of course Russ!
I replaced R5 to 5R, readjusted voltage and max current, then connected, and fine tuned, I can now shunt what I want!
Great!!

Tom :-)

Micro details, timbre, air, blackness, instrument separation has improved...

Thanks Russ!!

It's -15 centigrade (5 fahrenheit) outside, snowy and the tubes and BII are glowing and keeping me warm...

Best
Tom :-)

It's 37ºC (98ºF) here, and my placids get nice and toasty in this sort of weather.

Not that this particular snippet of information have much to do with trident regulators Whistle

a short? you mean a jumper...not sure I have 5R at hand
still waiting for Norwegian postal (lack of ) service

Yes, a jumper instead of the resistor (or across it, your choice).

Hi Russ and Brian

How much individual current is required by the oscillator, chip core and digital circuitry respectively? I.e. how much current must each Trident provide to its respective circuitry?

Thanks

Paul

I could tell you , but why not just measure it? :)

I don't have the numbers in front of me at the moment. But we can post later.

Tridents are installed and it works fine Angel
Sound is more refined, aerial, nuanced and relaxed.
It shows that supplies are very critical.
Good job!
