Sorry, not trying to be annoying just trying to understand and, if I am reading the schem right, help.
To be honest, I only looked at the schematics after you pointed out something was wrong, but as far as I can tell the schematics are correct for the actual hookup, which works.
To start with, for the LoZ out I use an XLR because the gear I might plug into will have an XLR connector. I could have used a jack plug, I know. Where do I the cold from? I never shot for a balanced out, I just connect with an XLR and have a separate shield, it´s one pickup straight out of pin 2 & 3 and shield 1 and I see no point in complicating things at all. If I have said in earlier posts that I was going to balance the LoZ out, sorry, but that is not the point in this application. I am well aware that gibson only used a switch across the matching transformer, but you questioned the brown wire hookup to the transformer, which is believe is hooked up like gibson did. I think the signature series was connected something like this, with a TS for HiZ and a TRS for LoZ. I might be wrong, but again... as long as it works.
I´m sure you can google that if it is of any interest.
And of course the XLR and jack out cannot be used together, I hope I haven´t said that either. I have the choice of using either, using a TRS for the Hi out so I don´t need a switch to lift ground (or cold if you like that better) from shield. You obviously understand electronics, so there is no need explaining further why this cct wold not work properly
if I had used a regular mono jack for the HiZ in this application.
Vintage gear, well that´s anything older than five years (according to ebay
) so I guess that includes my two Yamaha mixers, but my three years old digirack protools setup was also noise free and sounded fine (with a regular 10m XLR cable) so if there is something wrong with the schematics, I honestly can´t find it! I´d have to open the cave and check, maybe I have looked my self blind on this schematic.
Please forgive me if it still is confusing, electronics in foreign languages is not my strong side.
You´d have to build one yourself
