Hello.I am planning to aleph J otherwise babelfish J after built F6.
F6 is amazing,I am curious about aleph J and F4 sound now.
My speakers are fullrangers and SB satori 2way 4ohm.
I read aleph J and babelfish J thread.
I don't need much volume, my room is so small.
My english and engineering skill is not enough.
Any suggestions welcome thenks.
 
Awesome-Looking Amp!

Paul 9334,

Beautiful amp with the Mac disguise. That would look nice next to my MC240 tube amp.

Where did you obtain those power supply boards? Did you custom-design it? I would love to use the chassis-mounted screw terminal type caps in my next Pass DIY amp build.
 
Hi I ran into an error while trying to bias the first board. My power supply is steady at 24v per side, yet when I try to adjust the DC offset on the first board I read 20volts! Am I reading this wrong? I'm able to put the bias right at .450mv.

Also for c6, do I need a jumper there if I don't have a cap that will fit? Or do I just leave it completely alone?

I had the same problem when I powered up one of my monoblocks the first time. In my case, it was enough to play with the DC offset potentiometer and adjust bias afterwards.

No voltage across R18

I finished my Aleph J build last night, and everything was going perfectly until it wasn't. I have +25.4V and -25.4V off the power board. The right channel worked perfectly, 400mV over R18 and 0mV DC offset.

The left channel is a different story. Both LEDs are lit, but I'm getting no voltage over R18, and nothing is heating up.

I'm not sure where to begin the testing process to determine where the problem might be.

Any help would be appreciated. Thanks.
