6C leslie connector?

[Guest]

Hi all, I just came into a Leslie 251 and found out that it needs a 6C Leslie connector, something that I don't have. I'd also like to hook up a 147 to the same organ....is this possible?

You don't mention what type of organ you want to connect to so I really can't offer much help. A 6c sounds like a Leslie/Conn preamp number to me used for connecting a 51/251 to a 700 or 710 series Conn console..</P>


The 251 is a two channel leslie and the 147 is single. They require different pinouts for hook up even though they are both 6 pin. It would be possible to connect both to the same console but they could not be daisy chained. You would need at the very least seperate outlet boxes for them or custom cableing. If you plug a 251 into a 147 outlet "poof", you let the smoke out of the amplifier ( to quote my friend Rob)!</P>

oh yea.. sorry about that. I'll be hooking it up to a C-2 I believe.

Friends of mine did just this - after all, a 6 pin leslie is a 6 pin leslie, they thought. Worked fine for a while, though they did think it strange that the 251 ran on chorale when the organ's tab said tremolo. Then, the aforesaid leslie did indeed let out the magic smoke!</P>


Enter the store's annoyed engineer, with mutterings of where he was going to put the 6-pin cable next!</P>

Andy,OUCH, I hope generous amounts of Hammond oil where available to help him (the engineer) plug in that Leslie cable!</P>


Ok, back to business. Now the 6C makes sense. You have a Hammond C2. 6C is the type of connection or pinout needed to connect a Leslie 251 to a TWO CHANNEL Hammond such as an A100 or M100. Look at the pinouts (6C &amp; 6W) at the link below. Your C2 is single channel so there will be nothing to connect to pin 5 of the 6C/251.</P>

Notice that the jumper between pin 4 and 5 for the 6W pinout for a Leslie 147 would send AC voltage to the stationary input of the 6C Leslie 251. To complete the hookup with both Leslies of different model, you will need two 6 pin outlet boxes each wired and correctly labled for each Leslie. You should be able to use the same chorale/trem switch for both. If you do not completely understand how to make this custom connection please call a tech to do it for you. Leslie 251 amps are worth about $350-450 and I would hate to see you fry yours. An error here would most likely resuly in a total loss of the amp and possibly the dividing network and drivers.</P>


With a single channel C2 Hammond you would not be using the stationary (reverb) channel input to the 251. Removing the tubes from the stationary chanel of the amp would be recomended. I have a 251 connected to my RT3 and have done this. It is now basically a 147. I removed the jumper between pins 4 &amp; 5 in a 147 outlet box.</P>


You will have one screaming C2 when you get all this hooked up. </P>

thanks so much! i think someone had it hooked up to something single channel already, because I did notice that one of the 251's tube was missing..i hope its the stationary channel tube..</P>

Re: 6C leslie connector?



I've run a 51 and a 147 through a relay that I built myself. I had to build a pigtail for the 147 that excluded the reverb signal.</P>


The big difference is in that that the 147 (Wurlitzer type?) uses pin 5 as the other side of pin 2... The 51 (Conn type?) uses pin 5 as the reverb signal. </P>


Read the schematics for both the "W" type and the "C" type, and the differences become clear.</P>
