"invisible amplifier"
low budget office amplifier project. Invisible between other Measurements equipments ;)
15€ TDA Board
17€ used toroidal transformer
15€ old enclosure from a TAYLOR-HUDSON
~ 20€ connectors, capacitors, Fuses etc.
I designed a holder for PCB, Capacitors Fuses and so on and 3D printed it.
Fuseholder (primary) , 230V Connector , Knobs used from the old enclosure.
VU Meter function also works, with a small circuit i made.
A few more Pictures and ( german ) description you can found here:
