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

The Ultimate Tone, Volume III by Kevin O'Connor Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self. Note: The Ampage Archive is an Amazon Associate site.

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
