filter Caps

My ancient and honorable SB-610, circa 1970, is beginning to show signs
of aging. Most evident is hum modulation on the scope patterns and tone
outputs.

For a start I need to replace the low-voltage filter cap, C602. This is
Heath part number 25-63. It is a can electrolytic containing four caps:
30-20-20-20 mfd. I think the voltage rating is probably 350 working
volts.

Also showing signs of leakage are C600 and C601. These are 40 mfd at 450
volts. Part number is 25-41.

Any ideas of where to get replacements for these will be welcomed.
