Hi All,
I picked up a very nice L4B the other day that works FB (only used it on =
40/80m though). When I took it apart to clean the tubes and dust off =
the chassis I noticed that two of the three 15ohm 2watt resistors on the =
each suppressor was completely burned through in half. Interstingly, =
one resistor out of the three on each one looks like it never got hot at =
all. I am going to replace all the resisters but I was wondering why =
two out of the three resistors are almost vaporized while one is intact. =
I dont see any sighs of arcing or overheating anywhere else in the amp =
- it looks like brand new otherwise.
73,
Kevin
