Thought for 18 sec — Choosing components for low-power MCU
Found 3 results for Find Flux library USB input eFuse or protection switch IC for 5 V USB-C sink with adjustable/current limit around 0.75 to 1 A, overvoltage protection threshold above normal USB 5.25 V and below 9 V, undervoltage lockout, reverse current blocking, soft-start/inrush control, active SMD part. Prefer TI TPS2595 TPS2596 TPS2594 AP2265 AP22802 style eFuse..
I want to make a single ended KT88 base tube amplifier. I want the output to be 25W into 8 Ohms. The preamp stages will use the 12AX7 tube. The KT88 bias should be adjustable. There should be an effects send and return loop. The tone controls should imitate the fender tube amplifier tone stack.
No design changes were made. This is a new mains-powered, high-voltage tube-amplifier design, but execution is unavailable because the account has no available ACUs.
Remaining work:
Resolve a key feasibility issue: a single-ended KT88 typically cannot deliver 25 W cleanly into 8 Ω; expect roughly 10–15 W, or use parallel KT88s/push-pull for 25 W.
Define mains voltage, speaker/output-transformer requirements, feedback topology, and effects-loop signal levels.
Design the 12AX7 preamp, Fender-style tone stack, buffered effects send/return, adjustable fixed-bias circuit, KT88 output stage, and protected high-voltage/heater supplies.
Add shock, fuse, earthing, discharge, creepage, and enclosure safety provisions before schematic capture.
