Hello my name is Keith, i am very new to the forum world so please forgive me if i do not know all the rules of posting and things,
I have a ADA MP1 that i am having issues with, the sound coming out is very low even threw the headphone jack, i think it is a version 2 when i power up it indicates 2.00 but dont quote me on that one, i have cleaned the input output jacks with no luck, i have went threw and checked all opamps and good +15Vdc and -15Vdc on pin 4 and pin 8 the input jack on the front looks pretty dingy so i may change that, but my ADA was working just fine and then the sound went very low even when i turn up the volume can barely hear, i do not know much about programming side, so i edit #1 and set gains and master to 10 and then i get some sound, i had to change the battery and i used a computer battery holder and soldered that in and fresh battery, cleaned boards real good still no change, i havent changed out my tubes because i dont have any handy laying around but i will pick some up, very stumped, not happy my ADA is messed up, Please would anyone be able to help me with this problem?
