GB For Salas SSLV1.3 Ultra-BIB

[shattered_dream]

What kind of heatsink would you recommend ?

 

[Salas]

Depends on your voltages, CCS setting (current limit), and load consumption. Different levels and settings and loads create different states of power dissipation requiring different sinking area.

When's the next group buy for this with minikits?

Uncertain.
I am currently out of boards. I can sign anyone up on next Spreadsheet.

Please sign me up to 2 pcs. Thanks

Hi,
Please add me for 2 boards and kits for this.
Destination Vout +15/-15 and +5 on each boad.
Will be good if you add option for Full kits but without power transformer.

Please sign me up for 1 full board plus corresponding minikits.
Thanks,

Done. I edited my signature to include the next GB. So it's now open for business and sign up.

My BiBs have powered 3 preamp boards. Its great having the versatility with the BiB. I can swap the pre boards with molex, adjust the BiB voltage, bias and enjoy a different preamp! Its fantastic.

Heh, the BiB could be an amp itself.......

Added myself to the exel table.
Minikits will be add later?

 

[alopa]

can I get the salas boards and kits now. Just heard about it. Kind Regards, Alopa

Please may you put me down for 1x board with the corresponding 2x positive and 1x negative mini kits, thanks! Target voltage is low for all three regulators: 5v to 15v - maybe upto 24v absolute max (by the way, does specifying 5v have any drawbacks? Does it affect performance or limit max voltage you can set for example?).

 

[Salas]

No true drawbacks, 5V is within spec range. Specifying 5V is about getting handpicked low IDSS J3 so its VGS(OFF) will not be high and squeezed at what VDS minimum J3 will see with 5V out (VDSJ3=VOUT-VGSM2). So its just for guaranteed 5V performance and not affecting any higher range. The Spice open loop gain analysis shows same high gain same shape and same 60 degrees phase margin at same zero gain frequency both for 5V or 15V output by the way. But a real M2 MOSFET will have lower Ciss Coss Crss parasitic capacitance curves the higher the VDS across it (i.e. Vout in this circuit). So you may say it will be performing faster beyond 10V but its no slouch at 5V.

Hi, I just signed up for the BiB boards and Hotrod DCB1. Thanks!

 

[GoJuice]

Thanks, Salas. I have lots to learn.

 

[GoJuice]

In the sign up sheet it says DC Flexy (2 boards) $16.

Since there are 2 per board, you would get 4x DC Flexy modules for $16 if your name is down for 1x DC Flexy. Is that correct?

 

[Dadbeh]

when does this end? im in a hurry to get the boards.

GoJuice, not sure if Tea has gotten back to you, but for $16 one gets a pre-scored pcb that can be separated into 2 modules. It is a simple but thoughtfully designed module.

 

[alopa]

I am confused. where do I go to get the boards and what are the different boards I see above. Where do I go to get info about them.Thanks

Alopa, the gb moor Salas’ designs are run by member Teabag. Pls fully read the first post of this thread, including the info in Teabag’s signature.
Cheers.
