CV B+ problems

[kurtisthall]

Have a cv. Installed B+ power correctly I believe, (its only 4 wires) Removed ensamble switch, removed Tone Cab. Now have extremely low output and lots or hum that I didn't have when I had the tone cab hooked up. Organ played fine with DR 20 tone cab. TC had a bad tube or two and was hard wired to preamp strip and popped and snorted, but at least played. Sounded 100% better before I installed the B+. Now I used 12 gauge wire. Is that too heavy? Might it be the leslie connector kit? I am using a 46W. It previously had a 147 hooked to it.

Are you certain that it's not your Leslie 46W causing this?

Have you listened to the preamp directly from the G-G terminals with headphones, and/or another line out?

12 gauge wire is much too thick. I'd be concerned about the wire coming loose as it's too big to be secured under the terminals.

A photo of the preamp and wiring may help as a sanity check.

Some other things to consider:
1. 46W Leslie hookup is much different from tone cab hookup. (6H versus 6W. Study them please.) We are assuming you have wired a separate 6W pin socket for your 46W but if you have not done so you will need to
2. Verify the load switch of 46W is "open".

The 46W worked fine when it left the house and had been used with my M3. It even worked when the tone cab was hooked up. It is set to open.
I will double check my wiring diagram. May have to take some pics if I can't figure it out. May undo and resolder with smaller gauge wire. My solders seemed good but could be wrong. It was very hard to work with that gauge, so probably a bad idea.
There is a Leslie connector kit in the organ, but I don't know the number. It was hooked to a Leslie 147 before so the 46W shouldn't be a problem. The tone cab socket is kerput because the wires were cut off and the tc was direct wired, so no danger of plugging it into the wrong socket.

Thanks for the advice.

6W hookups do not need a Leslie Tremolo kit.

You might have a Leslie Tremolo kit designed for 122 type (6H) Leslie hookups. Be careful.

I will check it out the Leslie kit number. I don't think that's the problem because with the tone cabinet and leslie 46W hooked up together, I had correct volume and leslie function, just bad tube noise from the tone cabinet. I probably would have found out instantly too. But, be careful is always good advice.

I don’t know what type of power supply you used, but if you installed the ever popular International Power IHB200, make sure you didn’t forget to install the correct jumpers on its primary side (depending on mains voltage where you live)

[kurtisthall]

Jumpers were installed. I'm gonna do over and see if I can fix it.

[kurtisthall]

its a 26-1 connector box BTW, for the 147

[kurtisthall]

I got it.
You cannot disconnect the Ensamble switch, even though it serves no function after removing the tone cabinet, because it breaks a circuit, which I kinda figured.
Everything works fine and it sounds pretty good for a 70 year old Hammond! Just have to oil it, cinch up a few wires, and polish it up.
