Correct. It also applies to a single two (or more) way HiFi speaker. If one of the drivers isn't connected properly, i. e. in phase, one will observe a nasty notch in the xover region, acoustically

Flipping the wires to the treble driver in a Leslie indeed changes the phase relationship, and while this might seem subtle in some contexts, the impact on the crossover region is real and provable.

Hi Christoph, Not to beat the dead horse too badly, but the stereo example was to illustrate the original concern about how to phase a speaker so it will play well next to another speaker. Indeed to

Hugh, I‘m not speaking of a stereo system with its two speakers. And also not about two Leslies. The issue is alone about the question whether it is important to wire the woofer and the treble

Christoph, Please sit in front of your stereo speakers and listen to something with bass, maybe in mono. Then reverse the polarity of one of the speaker connections. In one case the bass will

The human ear cannot hear the phase. It only can hear a phase change. If you enter the root with the Leslie spinning, you cannot say, whether is in phase or out of phase. Also the phase is frequency

I witnessed it with my own ears. I put a sine wave tone at 600-700hz with the motors stopped and then physically reversed or flipped the phase of one of the drivers. It very easy to tell which way was

Uwe, I believe you are wrong in your claim, that "out of phase connection of both drivers will result in a considerable notch in overall frequency response in the xover frequency region". This is a

My schematic shows a 47R resistor R699 as part of the snubber network, --

The components you're looking for are C621, C622 and R699 in the schematic. Two 0.1uF capacitors and a 47R resistor. These capacitors,

In the UK, Mouser usually is the best distributor. But take care of their minimum order. Years ago I bought a bag full of 0.1 ?F 275 V~ X2 capacitors from a German surplus dealer for almost nothing.

Hi, thankyou for the help. I am in the UK, can you advise the best place to order the parts. Happy New Year to you all. cheers

You're absolutely right regarding the AC thing. But an out of phase connection of both drivers will result in a considerable notch in the overall frequency response in the xover frequency region. And,

Happy new year to all! The Leslie control schematics show a SPDT contact set relay with a pair of 0.1 ?F capacitors (C621, C622) across the points. No resistor. Yes, due to their age these

Underneath the amplifier chassis, near the speed control relay there is a suppressor network consisting of two 0.1uF capacitors and a small resistor (33 ohm if I recollect). At least one of those two

Hi Paul! I'm not at the same location as my service manuals at the moment, but I strongly suspect that if your T500 is still in reasonably original condition that you'll be able to find a capacitor

Hi, when switching slow to fast or vice versa on the red Tremolo switch, there is quite a bang through the speakers. I seem to remember that a while ago my local organ tech (now retired) advised it

That would sound great. I used to do something similar with a H&K Tube Rotosphere... I would simply go through that to get the drive, and then also go into the Leslie amp. This gave a simulated Leslie

I like that. -- Rich Reid 208-861-9263
