"Cigar Box" Amp

[galejt]

Well. No luck. The board is the cleanest I have ever built, no slop, no visible solder bridges, cleaned every part with steel wool...and no sound.

I somehow lost a couple of caps (or my foster kitten removed), so I substituted film caps @ C8, C6, C1, a silver mica @ C26 (12p was all I could find) and an MLCC @ C5. Other than 12p vs. 15p all values match.


I get a faint click through the speaker when I plug it in loaded. The battery gets hot quickly. My meter wouldn't resolve any voltage across the 1ohm-1W resistor.

Any thoughts before I order one built?

Thanks. Jim
