It is never too late to incorporate good engineering practice.

Perhaps someone saw the autopsied gold-sputtered 8877 on my Web site
that was a pull from an AL-1500?

Every manufacturer that I'm aware of on this planet, except
Ameritron, uses a parasite suppressor on their 8877. I'm doubting
that everybody else is out of step and only Ameritron got it right.
Just how the AL-1500's designer came to the conclusion that 5000-ohms
of feedback XC at the tube's max freq rating could not cause
oscillation is a mystery.
