Question about Crate FlexWave FW15 Guitar Amp Combo, 15 Watt Single 8 Speaker
Witth an oscilloscope analyze the ripple voltage across C67, C70, C14, and C12. Pay close attention to the last two of these which are on +/- 15 volt lines.
The "chirp" when shutting down is LIKELY normal and would probably be from teh DSP effects unit as it goes down. The voltages go out of the operating range and the device essentially goes nuts for a second or so.
