Kenwood KA 9100 Part 3

In this part, I show how to test transistors o the circuit board.
I also replace the capacitors and check out the preamp and tone control board.
Finally, I replace the old TA-100WA Power packs with the new replacement modules from Pyramid Audio. This is not a paid add for Pyramid Audio. I purchased them through their eBay store after reading about them. Hopefully, they will prove to be a good substitute/upgrade for the old TA-100WA modules.
