Hi all,
My K3 is a #1255.
I've done all the mods myself. I'll give you a roundup of that , with
the results:
*Solving a problem:*
- K3 Synth ALC = That was a really necessary one, I had that problem and
it needed to be fixed
- K3 external ALC Mod = Necessary since I started to use ALC when I
bought rhe KPA500. Before that I used all Amps without ALC. Actually,
now Ithat use the KPA500, the ALC is set at such a level that it well
never react :-)
- 12V ERR mod (13.8V supply to PA in K3 fails due to bad connectorpins)
= Had this problem last year. Decided to make the Field-fix instead of
changing the connectors. This means bridging the connectors with a wire.
Easy! Good chance that you will run into the problem at some point.
*Improvements:*
- IF output Buffer Gain = Good mod! I am using a softrock and NAP3 for
a bandscope om my stations pc
- AF stage upgrade (line out and speaker amp) = Yes, it helps
- K3DF DSP Low Pass Filter installation = It really makes a difference.
*Do this one*. I noticed that I could sit at the K3 for much longer when
I participated in a contest.
*
**' Maybe' Improvements*:
- Front panel Macrophone Circuit MOd = No difference, I had no problems
before that but I did this one together with the LPF installation
- Improving Immunity of the rear panel RS232 and audio connectors = No
difference because I did not have any problem before the mod.
*
**Precautions*:
- K3 AF amp output mod = just a precaution. Never had a problem since I
use stereo computer speakers and not a mono speaker.
- K3 automatic Frond End Protection = Just a precaution. No difference
noticed, I did not have a problem before the mod.
I hope this list helps you to decide what to do.
