SSLV1.1 builds & fairy tales

thx

surprised to see that you have so much components In Vref loop
Isn't just leds and resistor better

Again, do a proper test on the mosfet you removed to be sure it was not damaged.

I can't do it, I don't have the mosfets (I threw them at the garbage).

That one needed to be Vadj. Its still a resistive and LED Tc thing.

for me more resistence mean more Vref variations
for 24 V ref In pre amp regulator I use hypno with only leds

Not a great deal, goes steady in a matter of warm up time that Adj one, +0.3V from cold, and then never moves. The dynamic resistance is better with only leds though. If you use it for one certain app and can afford custom board area that is.

How low can the filtering cap (Vref cap) go if using only leds for vref ? Can we use films 10uF ?

 

[Salas]

Yes as minimum for phono.

NP D1 I/V powered with Salas SSLV1.1 BiB regs is singing very very good

hoo ray

Hi, anyone here built 2.5A - 3A version of BiB for T amp? What is the recommended mosfets used? Any help will be appreciated. Thx

better than LM317 ?
where do you find benefits
what are your PSU voltage and CCS

 

[AndrewT]

Tham,
where will the T amp get it's current from, to meet the transient current demands of the connected speaker?

 

[merlin el mago]

better than LM317 ? yes
where do you find benefits more bandwith so more music also less less noise
what are your PSU voltage and CCS +-15V 200mA aprox.

Hi Andrew,

Don't quite understand your question...I have a V1 Salas shunt set at 2.5A now providing the power for a T amp and it sounded much better than a 4A smps I had earlier.

thx for reply merlin

how about bass - Is It fast and detailed

samoloko all depends of the rest of your system & application, all Salas regs are very good: fast, transparent, with better bass mids & highs all very detailed.

 

[samoloko]

what type and value are you using for ref filter cap and out cap

at 30V 200mA your fets are hot

 

[samoloko]

IRF240 / 9240 are much better cooling
