Hello,
were you ever able to get this service manual?

I have a Proel Flash 12A that I need to repair, tried to contacting Proel for the service manual or schematics but it was a dead end and can't find service docs anywhere

thanks

I always search first in Electro Tanya, great website by the way.
Those are for the "Smart" model and I was looking for the "Flash",
2 different units.

Anyway, I contacted Proel again yesterday, and today they sent me the schematics over email.
what a great service I couldn't be happier.

A big applause for all the companies that release schematics so that they're units can be repaired.

I uploaded the schematics to the Technical docs section

Hi ,
thanks for post,
unfortunately still not found thats schemes about the subwoofer 15SA,

the subwoofer issue was caused by a quite big resistor vertically mounted,
too near an electro cap body ( so bad design ? )

that above a certain volume due to vibrations generated by the woofer
the resistor metal pin uncovered went to touch the body of that adjacent electro cap
making a short that burn the protection fuse (fortunately)
without damage other parts,

bent a bit the resistor moving it away a couple of mm from the electro cap
and covered the metal pin with insulating sheath
the subwoofer has not given any more problems
and it is still in use,

if not already checked,
maybe it could help,
"whoops" has kindly posted a doc here
