Replaced line cord, selenium rectifier, output jacks, filter capacitors and resistor, AF oscillator capacitors and two RF output resistors. Good cleaning and re-alignment of the tuning capacitor plates and she runs as good as new.
Nice job on the SG-8. I have had a couple of these over the years but both developed problems with the main tuning cap and were unrepairable. That being said, would you like a set of original SG-8 knobs?
