I need the help of you folks who own or have owed this great little
British amp. I purchased a Quad 405 (not 405-2) on Ebay. There are
some inconsistencies with this unit that have me confused.

Unit Serial # 37277
Board #'s M12368 ISS9

These don't seem consistent from the infromation I've read. Is this a
later version of the original 405 - but with somewhat older model
replacement boards or what??

In addition, the rear panel does not have the typical circular voltage
selector dial. In the general location of where the dial would be is a
single screw head. On the inside that screw holds in place what is
clearly a factory installed second set of power line fuses (they look
like 6 amp fuses) in addition to the standard single 5 amp rear panel
mounter fuse. So in total, there are 7 fuses for this unit. 2 - 4 amp
fuses on each board, the 2 - 6 amp fuses mounted to the inside of the
back panel and then the single inline 5 amp fuses on the back panel
that is externally replaceable.

Finally, on the left side of the rear panel is what I am guessing is
some warning language - but in FRENCH!! However, on the right side the
panel is warning language about removing the power cord - before
servicing the amp. This is in English!

So, for you folks familar with the Quad 405, is this a US imported amp
OR an amp imported to say the French speaking area of Canada? Second,
why are there 2 additional power supply fuses mounted on the inside of
the back panel? I have not seen this arrangement in photos of the
interior of the amp before.

I would appreciate any feedback!
