bought this off ebay this week i was told it had issues with a crackly input a Dynacord bs412
but i figured west german engineering at its finest would be repairable
took the preamp to pieces hoping not to break anything the two inputs had crumbled through years of use and were in pieces also the output volume needed resoldering
i found a suitable pair of input sockets on ebay,arrived today have soldered everything in and reassembled and im pleased and relieved to say it works! hopefully it will live another 25 odd years life.
im really chuffed im a big phil lynott fan and know he used these in the later thin lizzy era
will have to fire it up tomorrow with my ibanez rs900 and don the studded strap to see if i can get anywhere near the sound
