More Beta decreases the amount of input/base current needed to produce the same output. More Beta does not increase the V-gain of the stage. In other words, more Beta raises the input Z. Rich Measure

The trouble with varnish is that it leaves air pockets inside the transformer because it's volume decreases as it dries, This is not the case with resins that use a hardener. Rich Measures, 805.386.3

2100v is too much for 811As. The HV PS power supply's regulation can be improved for SSB by resonating the filter choke at 120Hz with a cap. However, for AM there is no benefit. Another improvement i

Carbon-film resistors make good grid-fusing resistors, providing the W-rating is such that they are able to open fast enough to protect the grid during a glitch. For grid fusing with 811As and 3-500Z

Simple: Apply 10% of the V-rating, measure I, calculate Ohms. Apply 100% of the V-rating, measure I, calculate Ohms again. If the resistances are not within 1% of each other, the V-rating is question

If the load C is your typical 1500v air variable, and the DC blocker cap fails, the load C will act like a protective spark gap, and clamp the HV to c. +20v until the mains circuit breaker opens. How
