Hi
I am looking into a Dentron MLA2500A for a friend and need some advise.
The R2 1 ohm resistor fuse blew up disintegrated, the wire going to the HV
capacitor C16 is still in good shape (did not melt) as is the one going to
RFC-2. C5 looks OK also.
Only other thing I noticed were the two resistors of the parasitic chokes RFC-5
and RFC-6 did not look that great....
Not sure, but I guess the amp was modded sometime in the past as in-line with
both chokes are a couple of 1 ohm resistors in parallel that are not shown in
the diagram and i did not see in on-line pictures.
So, what would cause R2 to disintegrate like this? Could it be a shorted tube?
How to confirm this before we replace R2?
