My Take on X-BOSOZ

[steenoe]

Just went back in the thread and checked. Look closely here: http://www.diyaudio.com/forums/showthread.php?postid=763865#post763865
Normally the neg rail is done with the P-channel IRFP9610.

Doh!! Thanks Steenoe, I was looking atthe pre not the PS. 🙂

Easy enough to fix. Thanks for pointing that out! 🙂

Cheers!

Volume Control

How about the Attenuator ?
Which type will be the best choice ?

Fixed PS

NPN and PNP just as it should be. 🙂

Thanks for the correction Steenoe. Don't know how I missed that. 🙂

Cheers!
Russ

EDIT: I also added two more aeners for the negative rail so this PS can be more universal. 🙂 Thanks Tony.

Hi All,

Mr. Pass has very graciously granted permission to produce the boards. So as soon as I am convinced that the concensus is that the boards are satisfactory I will order a batch of each.

Cheers!

Getting ready to order

Question about PS and Pre board combos.

Which combo will most of you likely want.

1) 2 x preamp PCBs + 1 power supply;

2) 2 x preamp PCBs + 2 power supplies;


Trying to project the ratio of preamps to power supplies to order.

Thanks.
Russ

 

[hayenc]

prefer 2 and 2 so I can always use the power board for something else if I decide to change things.

 

[fcel]

2) 2 + 2

 

[Panelhead]

Order

2+1, to save space.

That reminds me. I meant to post he size of the PCBs.

The pre PCBs are about 4.6" x 3" each

The power supply PCBs are about 4.6" x 3.3" each.


Actually I am amazed they are that small.

Cheers!
Russ

Ps. Slight correction😉

NPN and PNP just as it should be.

Mosfet's are N-channel and P-channel😀

 

[promitheus]

2 + 2 is the best.
you made compact sized PCBs.
Not bad.
They are looking great.

Thanks Steenoe,

This is my first FET design, so I will need to catch up on the terminology.

Look like Most people will want 2x2 so I will probably make that the standard package. The good thing is even if you decide not to use the second PS you will have a goood one to use with another project. 🙂

Cheers!
Russ
