Question about how to hook up/power a Leslie 110 Cabinet

Post by John D Miller »

Hello
Looking into getting a Leslie 110 Cabinet.

It is set up with a quarter inch speaker cable that can be connected to an amplifier speaker out.
It has the 6 pin plug that goes to the cab and then plug that goes into a power strip (A/C).
It has a one button footswitch that does fast and slow (and I am assuming off/on?).

The speaker is a 12 inch 200w 8 ohm speaker.

I have a Custom Twin '65 with a 15in speaker and a Vibroverb (blackface w/ 1 x 15 in speaker) Both have the external speaker option. I know that changes to behavior of the output to the speakers "it would now want to "see" loads differently etc. If someone can explain how that works and if that is a good idea that would help me a lot.

The other way to go is power it with a separate power amp. I have a Peavy PV260 Power Amp (used for PA's I believe).

My chain is: Legrand --->Freeloader--->Earth Drive--->Hilton or Goodrich L10k VP-->RV3 (has stereo outs)-->to amp(s). So could send one to Vibroverb and then one to the PV260, then out of the PV260 to the Leslie. Is that good or bad or hard to tell.

Obviously, I want to work with what I already have and get a good tone and not blow anything up or melt anything, before going out and getting a Milkman "the Amp"

Thanks for any help.

Treat it like any other 8 ohm speaker, best results with the 8 ohm tube amps you listed will come using the 110 as the only speaker and not as an additional speaker, i.e. unplug the combo speaker and plug in the Leslie instead.

Also the switch does not do ON/OFF only FAST/SLOW

You can plug it into the extra speaker jack, then your total load will be 4 ohms (2x 8ohm in parallel = 4 ohms) which most amps can handle (but don't load it any further), but as was said, then you'll get half Leslie and half no-Leslie sound, so just run the Leslie alone.
