Thank you for taking the time to read my post and answer. Indeed the trimpots does not look very good. I will replace everithing that can be replaced. I ordered the capacitors and trim pots kits fom Danish Sound Parts . To date, I dismanteled the radio pcb ,the preamp, the amp , the switch bar and begin cleaning the pcb’s to remove the stiky dust. Still no trace of burning. Everithing is very brittle and managed to broke a SMD pad on the switch bar but luckily will be a easy fix. Need to be more careful.
Next I will desolder the switches and clean the contacts. Few switches have very oxidized contacts. Then I will dismantle the transformer and see how it looks. I will share my experience once I have something more done.
