The speaker's high voltage bias circuit uses a voltage multiplier circuit. It converts AC to DC through a series of diodes and capacitors, where each cycle of AC adds the capacitors charge voltage of the multiplier circuit to the previous stage. If you open the electronics boxes, you will see a...

I find ink-jet printers are sold like razors...the company virtually gives the razors away, because they make the real money on the blades. They just about give the printers away, because they make the real money on the ink. I use lasers for all my printing, I have both a monochrome and color...

My CLS's were an even earlier version, where they mounted the big audio step up transformer on the outside of the box. The high voltage bias voltage multiplier circuit has more stages as well (more diodes and orange caps).

General parts function:

The servo measures the actual speaker cone motion vs what the drive signal is. It then derives an error signal that it uses to modify the drive signal so the cone motion more accurately tracks the signal input. The servo sensor is necessarily attached to or part of the speaker cone, to measure...

I've had issues with a Velodyne sub that was servo controlled. It would give occasional noises even when disconnected from any sources. It seems the servo sensor was getting noisy, and the servo system would faithfully reproduce that noise. The only cure was a new driver (speaker) as the servo...

You can try swapping panels, to see if the popping follows the panel, or stays in the same speaker, that will let you know if it's the panel or speaker electrics.

The 75 ohm cable refers to it's impedance at RF frequencies, has NO bearing on it's response at subwoofer frequencies. A good shield is helpful to reduce hum pickup over it's run...that IS important at subwoofer frequencies. A better bet would be balanced cable, preferably shielded (microphone...

Problem is likely the TV, the soundbar just plays what it gets input. Many newer TV's will get software updates to fix problems such as what you're experiencing, you might check to see if the TV has the latest version installed. I had a Samsung TV that used to get the sound out of sync with the...

I pulled a dent out of my CLS with a small finishing nail that I bent the last 1/8 inch or so of the tip over at a 90 degree angle, so I could fish the bent tip of the nail through one of the perf holes in the stator panel, and hook it behind it, then clamp the nail in a pair of vise grips to...

This is incorrect, SS amps have much better control of the panels. The value that matters is damping factor, which is the speaker impedance divided by the output impedance of the amplifier. SS amps, unless very poorly designed, will have a much lower output impedance than a tube amp has...

Also, if you replace resistors, make sure the replacements are non-inductive. Many power resistors are 'wire-wound'...a resistance wire wound around a ceramic tube and coated with epoxy. The turns of wire form an air core inductor, so in addition to the electrical resistance, you'll also get...

Here is a typical ML high voltage board...the top left section is the music detect circuit, the input resistors and 4 diodes by the connector BB2 clamp the max music input voltage to IC1D to + or - .7 volts. IC1D amplifies the music signal and turns on Q2, discharging C6. Timing capacitors C5...

I have a Panasonic projector, and a 120" roll-up screen, so there's never much between the front speakers (ML Odyssey), and when there's no video, just a tug on the screen and it's gone too...equipment is on a side wall.

Make certain you make a backup copy of it to an external drive or the cloud, so hard drive problems don't render the collection inaccessable (been there, done that....NO fun doing it the second time).

I have lots...a few from female vocalists are: Patty Griffin - Heavenly Day from Children Running Through Cowboy Junkies - Cold Tea Blues from Pale Sun Crescent Moon Holly Cole - One Trick Pony from Romantically Helpless Karla Bonoff - The Water Is Wide from Restless Nights Suzanne Vega -...

Just a carpenters level against the front of the panel...adjust to get a centered bubble.
