If your STE has bad whittles or interference type noises in the audio, then give this kit a try! Please also note the STE PSU is likely one of the main causes of noise.

Kit includes 2 part assembled mini PCB's. Header stripes are NOT supplied or fitted. Please order a strip of item #0158.
Please note this kit might not solve all audio problems, but I have had reports that it has definitely improved issues for a lot of people.
NOTE - The green PCBs are slightly smaller and require the two tabs breaking off them. Fitting is otherwise identical to the purple boards as shown in the fitting instructions.
