I found this schematic in an old topic.
Who knows the value of the resistor which is covered by the lettering "STORE"?

there is an so-called current feedback amplifier. The speaker current is included in the feedback loop now.
The current feedback increases the output impedance of this power stage, thus the stage works in matters of damping like a tube power amp. Have a look to the Marschall Valvestate or Peavy schematics, there is the current feedback applied.

the value of R14 is unidentifiable in the schematic, what is the value.
