Hi there,
Suddenly on a L3 220v version (with p-2251 power transformer) i had a blown fuse (f001) 1a.
I just changed this fuse 1 time ; and the same...
I checked on the power board ; all transistors are ok expect q407a and q470b. All diodes and bridge are ok.
I decided to put out the q407a and q408a ; and same for "b".
I placed a new fuse of 1a ...and for now no sign of life...
Anyway , after putting light in my brain... if this fuse has blown, the problem comes from before the fuse...so the power transformer
In fact, i've on primary 11ohm
secondary : 1.2 ohm for red wires which supply the rectifier bridge
2.5 ohm for blue wires
Anybody can confirm whom power transformer is out ?
Thanks in advance for light
