is that a chance for me too?
Your channel is on the table. But if you like you can get some, because eight listed GB members didn't send info. Still a chance. 😉
LC,
Can we bridge two of those modules together for a 4ohm load? If yes, is one SMPS400 enough per channel?
If yes, please put me in for two modules
Thanks

Hello LC,
Just noticed this GB (been away awhile). Any chance on obtaining 2 boards for a stereo set.
If yes, do I send my address details to esl@siol.net
Regards,
Myles

I would not do that.Can we bridge two of those modules together for a 4ohm load?
Anyway, i believe the Group buy is over booked.

See post 2342
Ok so bridging not recommended. Still im interested in two more modules.

It is recommended, of course, with 16 Ohms speakers, and probably nice too with 8 ohms ones.See post 2342

Hi it is not that briding is not recommended, i am sure ESPERADO means it is highly recommended.See post 2342

It is because your mentioned PSU and load is at edge in bridge senaria.
I think you know relationship between voltage current and resistence, and here your SMPS400A180 data is not good for bridge setup as it is for single module setup.
For bridging it is best with 8 ohm loads, but can be done i think with 4 ohm with reference to post from LC where he mention one module can do 2 ohm if ALPS 8a limit never get exeeded. So you need to control input level in a way so 8a limit is in control.
When doing bridge version PSU voltage/current dimension is very different than single module.

Hi LazyCat,Last call for these 8 GB members.
Who will jump instead of them?![]()
Responding to your last call...
I'm holiday at the moment, and do not have access to internet evrywhere. Did you receive my email message? If not, i will sent it again.
Kind regards,

CCS FETs?
LC, could you tell us which depletion FETs you use for the input CCSs?
Are there SPICE models for these?

Hi there. Is there any chance to get a pair of this nice work ?🙂
Hello Olivier
Glad to see you here, Idefixes and Androuski gave you the Lazzy Cat virus? 🙂
Bests regards

2sk1530/2sj201 pair can be used in this circuit? No need to change? 🙂
Thanks!
You need some change since the mentioned Toshiba Fets not lateral like LC uses at the orig.
If you search for HexFet or Bipolar VSSA you will find already the schematic and layout for that version to.
I do not post the circuit here by respect to the topics.
If you do not find please PM to me and I'll help you.🙂

Hello Roger.
It's Nico2K3 who told me that these amps are great.
I had a chance to get a pair of them !!!
With the DSPiy i am sure it'll work very well.

Different mosfet structure, different temperature behaviour, 2sk1530/2sj201 pair would need temp compensation circuit.
