Yamaha DTXpress/DTXplorer/DTXtreme

Hi ppl

I've a DTXpress III with a PCY65S and a PCY65, both of which we've
discussed here before and the solutions have always involved taking
them apart and I haven't done that because until relatively recently
I've never successfully soldered anything so I kinda just shied away
from it. I've only one of each unit and I didn't want to knacker them.

The issues were, if I remember, the PCY65 giving an occasional bell
sound, and the PCY65S being unreliable as far as triggering the
different bits goes .. specifically despite setting self rejection
fairly high I can't seem nowadays to hit the front part without
sometimes also triggering the rear, sometimes the rear gives the sound
from the front, and choking no longer seems to work, it triggers
instead.

Well now it's all come to a head and I'm actually going to be playing
the darn thing live on the radio so I'd better get my act together. I
need to solve the problem pretty quickly.

So I thought .. I'll just buy a new PCY65S and a PCY65 and stick those
on. If we've still got the same problem I know it's not the unit, it's
a setting. If it's the unit, I can safely dismember the old units and
mess around with tinfoil till the end of time.

So my main question is .. might different units be a better idea? I've
no idea what's out there, but isn't there now a DTXpress IV and does
that have better cymbals and will they work? Or the XTreme ones?
Thoughts anyone on what I might purchase to replace. If you think
replace like with like, say so, tho.

And favourite supplier for same, is it still Thomann in Germany?

Cheers
