Acoustic B800H Bass Head Finally Dies
I recently acquired a Acoustic B800H head. Worked great for 3 mos. and then slowly but surely died.
When first turned on, it would distort but about 30sec. later would clear up and play fine for the entire night.
A couple of days later, same thing but about 5min. to clear. This pattern continued , "up to 30mins to clear.
But now she's finally died , just a low volume distortion when played. Checked the preamp section and it works great.
Inside shows no apparent burns or fried components. I tried chopsticking for loose connections or solder joints again nothing gained.
I can't seem to find a schematic so I could did a little deeper ...Thanks
