I'm hoping someone here might be able to point me to a schematic for a B&K CS-115 or 117 preamp. My long serving CS-115 has become non-functional and a schematic would help to troubleshoot the potential issues.
Based on online research I'm pretty sure the transformer is toast. I've also ordered a replacement input selector IC (Sanyo LC7818) as these apparently tend to go with the transformers. The IC in my B&K is definitely running very hot.
The B&K is getting paired with my Dad's old Hafler DH-220 (just recapped) and a pair of PSB Alphas for an office system.
Thanks in advance!
