Hi,
would this be the spoof from the ESP site?

The layout is terrible anyway

unclejed613 · 26th February 2007, 02:12 AM

layout might be terrible, but i have seen similar layouts in real equipment, like the bose 1800-V

Looks like a little better layout - 2 sided boards help a lot. But if the speaker output is the yellow wire, it's at the wrong end. The speaker out and the feedback tap need to come off the same end of the emitter resistor bus. Preferably, Bus-->Spk-->FB. Otherwise, a distorted signal can end up being fed back.
