Need some help to simulate Aleph 5

[guitvinny]

Hi,

I'm planing to build an Aleph 5, but right now I don't have either time nor money to build it, but I would like to simulate it. I'm using N.I. Multisim 10 and CircuitMaker 6.1 Pro, I am far from an expert with thoses software but I get something out of it... most of the time.

I have traced the schematic in both software, but I have hard time getting valid results. The Multisim schematic is inclued in .pdf format,you can PM me with your email if you want either .ms10 or .CKT file.

That would be great if you can check where's my mistake(s), right now the best I get is:

With Circuitmaker
A square-ish waveform of around 4mV p-p with 40mVDC.. when I applied an 1V p-p sin at the input

With MultiSim
A sin-like that swing from 43mV to 96mV and get attenuated at 43mVDC in around 30ms and if I place a multimeter at the output I get a read of 54mVDC

Thank in advance for the help !

Here's the .pdf from CircuitMaker

And BTW, the speaker emulator at the output is from www.aikenamps.com/spkrload.html

The frontend is not receiving +34V in both.

Connect frontend and see if that helps.

He he, wonderful ! I guess you don't see details when you got your nose to much into it ! Last thing, could you tell me how much gain should I get ? I got 25 Vpeak when 1V applied with this waveform

[rtirion]

Gain 20dB (10x)

1Vp in should give 10Vp out.

Great, I got it.. I think, a nice 10 Vp-p sin when 1 Vp-p is applied, is it supposed to be in phase ?

Yes

Great, thank a lot to everyone !
