I'm going through mods that were part of a kit that i have from Rich, AG6K(SK), for a dentron mla-2500 he shows to replace the 100ohm inductive swamping resistor with 200 ohms of non-inductive resistance and adding a fast-acting diode... so ok, i can understand going to non inductive resistance, and he has notes on the resistor values. ... but.. whats the diode for? best thought i had was for balancing out some non-symmetrical load? Anyone know, or is this one of those thoughts that should not be done???
