1.) I've checked C502, C503, & C504 out of circuit and each tested good.
2.) The voltage drop across R503+C503 is only 3 or 4 volts. Is this normal?
3.) I increased the resistance of R504+R524 from 3.6K+3.6K (1.7K) to 4.7K+4.7K (2.3K) and the voltage dropped from 58V to 48V. What are the downsides to increasing the resistance?
4.) As the set runs, the voltage at the collector of Q501 slowly decreases, but doesn't reach the specified voltage. What's lowering the voltage?
