"retro-4040" - Chip amplifier

This amp was started years ago but originally didn't work as expected. Two chip amp Jaycar kits have replaced the amp modules and the heat sink and PS have been beefed up. NOW IT WORKS at long last.
40W RMS into 8ohms with the normal chip amp protection all built in. Also power filter and 160VAC tranni. 10A rec. bridge (snubbed) and 2X8,000uf filter caps. Sounding clean, linear and uncluttered and bloody great bass - OMG! Nice WAF too.
