Well you guys are batting 100% so far i now have one more Ameritron 811H
question. I have replaced the grid resitor and replaced all four tubes (one
was shorted causing the resitor to blow). All is well works great never
better...switched to 240 from 120 and even better. Great output and amp seems
happy sounds and works very well.....
now the problem. To keep the fuses to spec Ameritron states a 8 amp fuse on
both sides at 240 volt versus 12 amp at 120 volts. It was running fine with the
original 12 amp ceramiic 3ag 250 volt fuses but thought i better get them down
to the rated 8 amp. Put in a set of C3ag 8 amp 250 v ceramic fast blo fuses and
switched on the amp.. nothing. a little jump of the needles bit nothing.
checked the fuses both blown.. tried again same thing. replace with 10 amp
fuses all ok.... voltage on the 240 voly line is near 240 so it is where it
should be
should I try/use slow-blow fuses at 8 amps. would that be better then the 10 or
12 amp fast blo fuses?
I do have a step start (slow start) device coming.. This might correct the
problem with fast blo at 8 amps.. BUT you guys are the experts..
thanks for any and all opinions...
Dan
