Kenwood A701A speed controller erratic?

The 450 ohm resistor may have gone & if you run at slow speed for 5 minutes your capacitor may fail with interesting results - smoke at the best.

Please see my answer for "Speed on my Kenwood 701A is same on all settings - can u help?"

Hope this helps if your've still go it.
