Nice matching set there, is that how the case come stock or did you add the front panel?

Looks like Ferrari's blue LED idea gets around (me too)

Thanks, it's a par-metal case. Front panel comes w/it.

Added an e12 and allowed for two inputs. Wire is from navships and canare starquad for the longer run (front to back). Ech0

Great looking amp. I like the clean front and back panels!

Cudos to you!

Hey MASantos, thanks for the kind words.

I'm still toying with changing the switch on the Sigma22 to a vandal switch. The vandal switch may tie in better with the amp with everything being round rather than a toggle switch.

I built this amp with a gain of 5 and it still is more than enough to power both the K701's and HD650's that I use. It will drive either headphone to volumes that I will never listen to. This surprises me a bit as I thought I was choosing a fairly conservative gain.

Nice job! I would agree that the vandal switch would look better. Just be careful if you need circuitry to run a momentary switch like the Bulgins.

Im most likely going with the vandal switch on my b22 as well. AMB has really nice board for this purpose.

I got them Kobiconns from Mouser, part number 161-7300-EX

Farnell has them too: 1267396

One of tangent's recommendations for 3.5mm sockets.

You should try the AD8616. With 150mA output current capability, it gives big sound from a small package.

I'm testing the battery. Still going after 14 hours. It should do 30 hours at least. This is the biggest advantage of the low voltage CMOS opamp.

Amp6 Basic:

Well it isn't a HP amp but I plan to use a tube hp amp as a pre-amp for this. Still have to case it. Next will build a millet starving student.

This is Morgan Jones amp that I built few years ago:

And this is the same amp but dressed few years latter in a new case.
