I don't think anything is louder really.. i mean the chopper and everything is loud as well (proper volume.. not cranked up) but the tank engine drowns those noises out. If I turn down the volume as you suggested, they all go down at those same levels so when it is barely audible, I can still hear all sounds but the engine noise overpowers all the others. And when the tank speed is at its max, or even close to that, it sounds like you have a bad channel on a car radio with HUGE engine noise interference comming thru yur speakers as well.

This meters out ok.

Within range... actually on the down side but in spec.

Replaced that cap and no go.. what do the opamps do? What actually amplifies the audio to send to speakers? There really isn't too much left on these other than those opamps.. even replaced the 555's and a couple more logic.. think only 2 or 3 chips left outside of the opamps.

I may end up doing that.. __________________________________________________________________ Looking for the perfect gift? Give the gift of Flickr! http://www.flickr.com/gift/
