WebJun 23, 2024 · For second circuit below, you’d need a potentiometer to adjust current. You can change RE to change range of current sourcing. For example with 12V max and RE=820 ohm, you’d have a range to 14.6mA. Also here a newer rail to rail single supply op amp would be used, not the 741 op amp. Image source:bristolwatch.com. WebIn a crate I found this amplifier board, Aliexpress origin, and decided to reboot my big ol' speakers :-). It's hooked up to a ferrite core transformer, and that's it. Plays surprisingly well and sits comfortably at around 60 deg C, 140F. Only thing is a constant low 50 hZ hum, not audible when playing, so I guess it's from the grid. haven place snf
