Hello Boogie Men ,
I'm Sebastien from FRANCE.
After reading all the posts on the 5Y3 and Fuse blow up on LSS, I discover someting strange that I want to explain here.
Maybe it could help some owers. Maybe not but its works for me.
I've ever tried 2 5Y3 NOS tube to replace the Sovteck or Mesa Stock Tube without good results : fuse or tube blow sometimes and the problem persists.
The LSS seems to be very sensitive to electric stability. So the first thing is to use a surge protection when you plug it. Moreover, always use a T fuse (temporary fuse).
The second thing I noticed appear when you switch off the amp :
Take care of the wattage switch : Put it on 30 watts position for the 2 channels. Don't let it on 5/15. So the solid state rectifer is used instead of 5y3 when the amp is stopping.
Same action when you start it again : put all the wattage switches on 30wts.
When the amp is ready to play, stand by ON and switch AFTER on 5/15wts.
The amp works well on all positions now.
Don't forget to replace it on 30 wts before switch off.
The problem is solve for me with this method.
Anyway, it seems to have a conception mistake on the circuit board or transformers.
Waiting for your replies and tests.
Thanks a lot.
