TOF-1 Amplifier Tuning Aid

The TOF-1 amplifier tuning aid is available. This board is compatible with most amplifiers, regardless of brand. It is now available in one model only that includes the overload relay, and the cost is $99 plus shipping.

This board features:

1.) Peak reading grid current allowing constant reading of peak grid current. Peak grid current is the single most important indicator of proper drive levels and tuning!

2.) LED warning indicator. Grid current exceeding a predetermined value flashes a red warning indicator.

3.) Overload relay. This circuit disables the amplifier at a predetermined grid current. The lockout is reset by momentarily placing the amp on standby.
