8877's heater whenever the transceiver is switched on.

// There are more than a few AL-1500 owners who have gone through more
than a few 8877s during the first 12-months. Nacherly, the expert who
designed the AL-1500 blames Eimac. /see Figure 24 on my Web site/ The
long excursion on the wide river in the Land of the Pharoahs continues.
- Before purchasing a used AL-1500 amplifier, I would perform the
Funderberg gold sputter test on the 8877. This test is described on my
Web site. The test takes about a minute.

// Even though the 3cx1200A7 has about 10-times as much feedback-C as a
3cx1200Z7, and, understandably, has a well deserved reputation for
squirrelish antics and big bangs, the filament helices are not nearly as
subject to bending as a 3-500Z's, so grid-filament shorts are rare
following a big bang. However, If I owned an AL-1200, or any
MFJ-Ameritron amplifier, I would add a suitable glitch resistor in series
with the positive lead of the anode supply.
