Re: HA-114 Treble springs adjust with Butter Knife or ?
I've adjusted them in place by using needle nose pliers to ever so slightly make a bend in the wire arm. Bending a wire arm toward the other will soften the tension, bending away from each other gives more tension.

I've adjusted them in place by using needle nose pliers to ever so slightly make a bend in the wire arm. Bending a wire arm toward the other will soften the tension, bending away from each other gives more tension.
I have also done this, but I use bending pliers, which are similar to needle nose except that the jaws are tapered and cylindrical in cross section. The rounded jaws prevent the possibilty of nicking the wire, which can cause "stress risers" which can result in the spring breaking later at the nick. I also use these pliers to form new custom springs from music wire. I have made little bending fork tools to modify springs in place when there isn't enought room to use the bending pliers. I sometimes post info and photos of my repair jobs on melnet. You could search there for more details.

Hohner makes diatonic accordion springs in three degrees of stiffness. The Corona model, for example, uses light, medium & heavy gauge springs respectively, for each of its 3 rows. The HA-114 uses the heavy gauge (approx .025" dia.) springs since it has fairly long & heavy pallet valves. I've found that substituting the light gauge (approx .022" dia.) springs works fine & improves the action considerably. I used to order the springs directly from Hohner (part #TA20151), but I have been winding my own replacement springs from #9 gauge (.022" dia.) music wire with considerable success for some while.
