HUZ: I assume these mods are good for the 32V-1 and 2 transmitters too.  I've heard this mod done recently on Steve's (KA1ORG) 32V. The difference was like night and day. Now Steve has a real nice smooth low end and very clean audio. This is an excellent mod that requires no blasting or drilling. The rig can easily be returned to stock condition for the collectors.
