Hi everyone.
A few days ago, I bought a Galaxy Pluto radio. Radio equipment sales
It has several modifications inside. Could anyone tell me what they were for? The board on the left, which contains something resembling an AF (audio frequency) amplifier circuit, has a blurred or obscured marking.
Board on the right side has a MN3008 chip. Looked it up, 2048 stage Bucket Brigade Device. So, probably an echo board. The board on the other side may be an audio amp for increased modulation on AM. Can't see it helping in SSB or FM. Best guess is somebody wanted an "audio monster" radio. But this being the internet if someone sees my answer as wrong I'm sure they'll chime in.
