I replaced all regulators and no more lights but lost phantom power. In your opinion, do you think I just need to replace the lm350t voltage regulator for the -18v and that fix the problem? I know the power supply connection to the board is good and can't find any other cause of the problem. Now, it's gotten to the point to where it does that with the meter bridge unplugged and can't even use the board. When I first plugged it in and tested everything, all seemed to work fine, but then, every time I hooked up the meter bridge the -18vdc light would go out and all the signal/peak LEDs would come on. Hey, I just picked up one of these mixers for $50 on Craigslist. Join us on Discord for support or questions. this will prevent them from getting fryed! Sonarr will be going dark indefinitely in protest against Reddits API changes which kill 3rd party apps. Clip an aligator clip between the solder gun and the body of the new part on each leg as you connect it. Make sure that you don't over heat them or they will be cashed right away. Un-bolted the old ones in the exact same spot re-bolted the new ones with heat sink cream, and soldered thr new legs to the old ones. instead of trying to de-solder the old regulators, I cut them out leaving plenty of leg length. they are the only part that is bolted to the heat sink when open the top of the cabnet. I changed all them anyway, I am sure another would have failed too. The only one that was bad in my power supply was the one for the +18vdc output. They consist of the following.ģ-lm350t from national semiconductor. The solution to power supply problem is simple.
