VSSA Lateral MosFet Amplifier

What power should i expect from a +/- 27V supply ? I have a rather insensitive/hard to drive 8ohm speakers 86db.

As you already presented, your speakers are quite insensitive so I would suggest you rather to use power supply enabling +/- 40 to 45 Vdc on the output. VSSA's peak output voltage swing is 2 V below rails. ;)


What is the input sensitivity ?

VSSA voltage gain is x22,28 means Av=26,96 dB, so for full (43 Vp) output 1,36 Veff is necessary.

Hi LC,

I was under the (mistaken) impression that only the PCB will be offered. As I already have all the parts, please remove my request from the list. I will have my own boards made.

Kindest regards,

M

P.S. It is amazing price for the kit, BTW.

Hi LC, could you also offer the power supply PCB, like the one that you have on your VSSA amp? This at least matches with the amp size and also an option for those who don't want to use the SMPS power supply.

You can get PCB only, no problem. As PCB layout is the last but not the least important part of the game called "Catch the SQ", I suggest you to try it. ;)

LC, do you have an aproximate date for shipping the parcels ?

Adrian

Let LC achieve test and writing built instructions....I purchase 300 ALF without any payment from us....so without any assurance that all guy will who subscrib will really proceed....Count between 10 to 14€ pro ALF and you will have approxymation what LC invest....
