Most folks simply went with linear fluorescent lights LFLs — and for good reason. They have quality light output, are one of the most efficient light sources available, and have decent lifespans. That being said, now there is a new player in the commercial lighting arena that promises even better efficiency: Tell us about your fluorescent lighting application and we will suggest an LED alternative! To help you decide, take a look at some of the benefits of T8 LEDs: This makes them safe for the environment. Dimmable — Many LEDs have full dimming capabilities, whereas fluorescents are expensive to dim and do so poorly.

Narrative Description of Amplifier Circuit Function This amplifier provides watts power output for the Six-meter band. It uses the low cost GS35B Russian power triode in a grounded grid or cathode driven configuration and requires about Watts of drive power. The Russian tube is currently available from USA and international sources1 at attractive prices, especially when compared to the cost of traditional American tubes of this power rating.
Before touching any of the wiring connected to startup or motor run capacitors, you should discharge them. Capacitors are electricity storing devices and can provide a nasty shock if it is you that provides the discharge path.
Is this the correct replacement for the model shown in my photo? I am concerned about the impeller lock bolt as it is too wide to fit in the new motor’s shaft. I know there are threads on the outside of the shaft that the impeller screws into; however, that leaves a large hole in the middle where the old bolt used to go. Do I need a new bolt, new impeller or does the bolt just get left off?
Hello Brett- The impeller screw is old technology and does not fit the newer motors. It is no longer needed and can simply be left off during installation. Can I use this motor as a replacement? It is not usually recommended unless the system is tested and recalculated to be able to handle the extra water pressure. Yes, this is the correct replacement motor for your motor model. These carry a manufacturer 1-year warranty. Please click here to view the warranty policy card. What motor and rebuild kit for the pump to you recommend?
Just be advised that if you have the copper cone insert in the seal plate then you would need to remove it. An up rate motor is the same term used as a regular motor.

Doug Schroeder September PureAudioProject Horn1 picture courtesy of the company It figures, the one category of speaker I thought I could safely ignore through the years is the one I should have been paying closer attention to. What was I thinking? That higher power equals superiority? That nothing tops an electrostatic when it comes to cleanness and detail? That horns are problematic, too finicky?
These perceptions were all wrong, obliterated by the experience of hearing the PureAudioProject Trio15 Horn1.

Motors used in HVAC such as the condensing fan motors or blower fan motors sometimes need help to get moving and to stay running at a steady pace, with no heavy up and down spikes. Not all motors will have a start or run capacitor some can start and run by themselves. Capacitors in HVAC can be separate or can be in a single package. The Dual Round Capacitors are simply the way engineers are trying to save on space and cost.
They could have put two capacitors in a unit but combined them in a single package. A dual capacitor will most often have one side to start the compressor Herm and the other side to start the condensing fan motor. The third single leg on a dual capacitor is a shared common leg. A Start or Run Capacitor can be combined into one capacitor called a Dual Capacitor with three leads, but can be split between two separate capacitors.
The Start Capacitor gives a fan motor the torque it needs to start spinning then stops; while the Run capacitor stays on giving the motor extra torque when needed. If the Start Capacitor fails the motor will most likely not turn on. If a Run capacitor goes bad then a motor can turn on but the running amperage will be higher than normal causing the motor to run hot and have a short life expectancy.
If the unit has two capacitors then one is the Run Capacitor and the other is the Start Capacitor.

Just what is tone? What is a good tone and how do you achieve it? Which amps you should choose for your setup and how to get the tones you want.
The Patterson PR was a “Los Angeles-built,” superheterodyne communication receiver that was produced early enough to have many unique or, at least, unusual design features.
You can run this piece of chalk! I do remember that time Bill Rogers and I were in a power shed out in the middle of the desert, maybe 25 miles from an oiled road. But there we were together wondering exactly why we heard that Generator Groan! It would have been easy to walk away, but to leave the riddle unsolved? Many folks who live off-grid do. A typical inverter-charger like the Outback FX series goes into battery charging mode whenever the AC input is hot.
When AC input voltage and frequency are within tolerance, the load is transferred to the AC input and the battery charging sequence begins. The typical small generator is an inferior source compared to modern sinewave inverters. Voltage and frequency are rock solid. Just get a big truck or bus alternator, turn it with the prime mover of your choice, and connect the output directly to the battery bank.
Even at 24 volts there are alternator options, but the price goes up considerably think aircraft industry. There are no affordable 48v alternators that I can find anywhere. By the way, a very skilled DIYer by the name of Bob Gayle — who is now the mayor of his hometown in KS — has had good success boosting the output voltage of the Leece-Neville series the triple nickel. An effort will be made to quantify the difference later so you can decide for yourself.

Some of these features became “standards” for communications receivers while others are only found on the PR and its matching Pre-Selector. Besides its unusual design, the PR has an important place in history relating to radio manufacturing on the West Coast in the s. The PR has always been a favorite of mine, probably because it was the first communication receiver I owned at age fifteen. This write-up includes circuit details, restoration suggestions and a performance report.
Before , radio building on the West Coast was uninhibited and pretty much any type of radio could be built and sold without very much interference from the license-holding and patent-owning radio manufacturers located on the East Coast. California was just too far away and their share of the booming radio market didn’t seem to impact the radio-selling profits enough to enlist infringement-busting lawyers to pursue those who were violating patents.
97 thoughts on “ Start and Run Capacitor Explained ” david October 1, Can I ask some question, because I am not very sure? What happen if hvac air compressor start wire is connected to the Fan terminal of capacitor? or connected to the large then system require herm terminal of capacitor (ex: system need 35 uf, but connect to 60uf)?
I need to replace the 1. The motor dimensions are different but they are listed as options under the Sta-Rite Max-E-Pro Pump replacement parts. You will first have to make sure that your filtration system and pipe can handle the additional water flow. Then you will need to replace the motor, impeller, diffuser, and seals. Is there any warranty on this motor? This motor has a one year manufacturer warranty. Russell, The USQ would be the correct motor.
I would also recommend buying a tune up kit so you can change the seals when you change the motor. They are 2 different frame types. What motor do I need? Do you sell the whole thing, pump and motor as one piece? I need a replacement pump for that.

This e-book covers the Light Emitting Diode. It has changed from a dimly-glowing indicator to one that is too-bright to look at. However it is entirely different to a “globe. A LED is more efficient, produces less heat and must be “driven” correctly to prevent it being damaged.
Asked on 10/20/ by. I just received my new Hp USQ Replacement Pool Motor for my Pentair Whisperflow WF pump. I am concerned about the impeller lock bolt as it is too wide to fit in the new motor’s shaft.
Features one channel and two inputs; volume, bright, treble, treble expander, bass, bass expander, bright switch, deep switch, stand-by switch, pilot light for stand-by and operate. This amp was built to play larger halls and outdoor concerts. The lack of reverb was not a big issue as most live performances had acoustics full of reverberation halls, arenas. Peter Traynor built these things to stand up to road abuse, unlike a lot of vintage stuff. It sounds great with either bass and guitar, providing a clean and loud tone.
Works great in large club settings. Front panel has two input jacks, controls for treble boost, volume, treble expander, treble, bass expander, bass, presence, and bass boost. There is also a standby switch and corresponding green and red pilot lights. There are no effects in this head, but stomp boxes work just fine. The front of the amp is wrapped in a Fender-style silver-face cloth [ There is also a cooling fan installed.
