New to this group, obviously. How I got here? ChatGPT. Why I'm here? I purchased a Kenwood Basic M2 in Japan in the early 80s to drive my Sansui PM-C200s (only released in Japan). Long and short of it is, sometime in the late 80s I shorted a speaker output, damaging the Sanken DAT transistor for that channel. I had it repaired at a stereo shop and it worked flawlessly for another 10 years before it happened again! At that point the entire setup went into the attic. Fast forward, my daughter developed an affinity for vinyl. We began buying old vinyl together at sales, used stuff stores, etc. Now I need something to play them on. So I pulled the old setup out of the attic, including my JVC QL-Y66F turntable. Now I need to repair my M2. I do have a smaller Kenwood amp in the interim but it does not compare to the M2. So the obvious question is... Is there an alternative to sourcing Sanken DAT1521N and DAT1521P transistors besides used on eBay? I know the drill. They were a specialty product produced for Kenwood and only used in the Basic M2 and Basic M2a. They have been out of production for decades and no data sheet was ever published. I am adamant about repairing this beast. Any insight is welcomed.
