Review on Nobsound Mini Bluetooth 5.0 Power Amplifier - Stereo Hi-Fi Digital Amp 2.0 Channel 50W×2 with AUX/USB/Bluetooth Input - Wireless Audio Receiver - PC Sound Card incl. Power Supply (Silver) by Mike Cox

Needed for some old Sony stereo speakers, flea market, stereo is long dead actually called?) I'm not sure if there is such a thing these days but I guess they don't have t. Since there were no connectors I just used bare wires to connect to the internal banana plugs. Man these things howl! Those vintage Sony speakers from the early 80's sound great! I think I paid maybe $5 for the whole stereo when it actually worked in the mid 90's, now I just use my iPhone for the bluetooth connection. Probably doesn't sound as good as it did when new, but enough power to blow some Metallica when I'm working in the basement.
