|J Fletcher||check the decoupling resistor|
If the value of the decoupling resistor has dropped, it would have a similar effect as the cap going bad. The older designs that used an 8 uf decoupling cap generally used a higher value decoupling resistor. Say 10K vs 4K7. Increasing the value of the decoupling resistor has a similar effect as increasing the value of the decoupling cap, but the available high voltage drops...Jerry
