I've have an sx-950 that was in need of a recap. I had borrowed it to my brother in law 8 months ago and he returned recently reporting it was "fuzzy". When I hooked it up it sounded good for about 4 LPs and then sure enough it was fuzzy. I did a full recap with the exception of tuner and main filters. I put it back into my system and listened to it for 4 days. It sounded much better, but by the 4th day it didn't seem as detailed as it should have been. Since I hadn't replaced any of the known problematic transistors I went back in and changed out the 726's and 1313's with 992's and 1485's in the phono stage. It passed the DBT, so onto the Power Amp assembly. I swapped out the 726's there and it failed the DBT! 4 transistors from the finish line and I'm stuck. I've looked for loose wires, bad solder joints, proper pin out, made sure the outputs were snug and tight. I went back in and re-soldered 922's, no change. Went back in again and replaced the 1uf and 2.2uf caps on right side. When I was de-soldering the 726's on that side I was wiggling one of those two caps thinking I was wiggling the 726 to loosen it up. Thought maybe I had a loose lead. No improvement. The leads on the small horseshoe shaped resistor that screws to the heat sink are intact. I thought now was as good a time as any for suggestions as how to proceed. I don't thing it's a good idea to continue to disassemble the outputs from the heat sink and manipulate the power amp board without a plan. It feels like I'm so close. I would really appreciate any assistance with where to go from here. Can I do pin voltages with the receiver on the DBT?
