There are two reasons why the TF may not save settings:
1) Most likely – you have a faulty or non-Eventide power supply.
2) Less likely – a hardware fault. We had one batch of units long ago where they installed the wrong component in the powerdown circuit, which can cause this.
A test of the power down circuit:
1) Power up.
2) Select a different preset.
3) Power cycle.
4) If the new preset is displayed, all is OK. If the original preset is displayed, the powerdown circuit is bad.
