There might be another reason for what you're seeing - Just guessing
Over the years I've had many dozens of them apart - most showed issues with voltage regulation under a load - all had the resister network issue we discussed and the small cap defective, many had the large front end caps defective - Just guessing here yours might be in the same boat - Just guessing......
