Pergo 15 Watt Amplifier Case (with XL6009 DC to DC converter)

thingiverse

This is for the VERSION B of the amplifier. The other version has a power entry on the front, but B uses screw terminals inside the case. I found a TDA7297 Version B 2*15W Audio Amplifier on eBay for $2.42! I thought what the heck for under three bucks, let's give it a shot. Boy am I glad I did - this thing sounds amazing and has wonderful clarity! Plug the phone plug-to-phone plug into the amp, Screw in the cables for the left and right speakers, screw a + and - wire to the DC-DC converter (OUT goes to the amp) (IN goes to the 5V USB power source). Turn the DC-DC converter screw to measure exactly 12 volts. Put all these items in the case with the heat sink up, tighten the volume nut, push on the volume knob and screw the case together. Turn the screws in and out a quarter turn back and forth until the threads are cut - PLA generates heat and then jams if you go too fast. I left the screw holes small so you can drill for your choice of screws from M2 to M3.5. I printed the front with the face up and used a lot of support, so it had a pretty face. This mode worked as expected. Additionally, I changed color in the last six to eight layers and gave it an aluminum finish - neat! * TDA7297 Version B 2*15W Digital Audio Amplifier Board Dual-Channel AC/DC 12V https://www.ebay.com/itm/TDA7297-Version-B-2-15W-Digital-Audio-Amplifier-Board-Dual-Channel-AC-DC-12V/391882075586?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 * XL6009 DC to DC Converter https://www.ebay.com/itm/DC-DC-Adjustable-Step-up-boost-Power-Converter-Module-XL6009-Replace-LM2577-Fad/182891738028?hash=item2a953273ac:g:mxsAAOSwnANZ4Hrq
