I have open here now a Pollard synth with power board that has an LM340t15 also marked 7315. A TO220 case with the center clipped. The other chip is a 5837m dip8 or i guess an mm5837m xfrmmer is a flathead lp 34-170 2 Lytics 1000uf 35 , 100 25 Anyone mature enough to help me pebuild this puppy, it looks primitive and easy to update ir am i mistaken. gw
