Wiring MM FTDO-59 OT in 5E3 Hi, I've gotten hold of a Mercury Mag. FTD0-59 output tranny and I want to make sure I wire this guy correctly. This tranny has standard 3 wire inputs but the output side has one yellow one and the other output wire is soldered to the side of the O/T housing. So I'm thinking the yellow output lead should go to the tip of the output speaker jack...but shoud I then ground the jack to the chassis in place of the normal ground lead that does not existfor this OT? I have a diagram describing the leads but they give no advice on the wiring scheme? Anybody out there used one of these?

Chris@CMWamps	Hi Mark     1st of all: be carefull with that yellow wire. The secundary ground is made trough the OT-casing & mounting and the amplifier-chassis.     Put the yellow wire on the "tip"/+ of the 1st speaker-output and you'll be fine (and your amp too ).     I've used a lot of those trannies and they're just excellent imho.     Hope this helps,     Chris     Ps Yep Bruce, no MM-shares for me

Bruce / Mission Amps	Ha ha... if you got paid a dollar from MM every time you've recommended one of their overpriced OTs to someone, you might be able to afford one yourself.     Bruce

TD Madden	Bruce,     Thought you were a supporter of MM xformers...have you changed your mind about their value?     Regards.

Bruce / Mission Amps	No, not really.   I still think they are too pricey but this is just a running joke between Chris and I.     Bruce
