PIoneer SX 450 Repair and Restore

This SX-450 was a bit rough when it arrived on the bench. After replacing the capacitors, and two transistors, It began to work pretty well. All of the switches and pots got cleaned and then we replaced the incandescent bulbs with LED's. The tuner really came to life after a proper alignment! I was amazed how good this little 15 watt per channel receiver sounds. I can now say that all of the '50 series receivers sound similar. The only difference is power and volume, but this "baby SX" really holds it's own!
