Telefunken Ar-51 Large Diaphragm Tube Condenser Microphone $1895 While Telefunken Elektroakustik is normally known for historic recreation microphones geared toward recording industry professionals who can afford the best of the best, the AR-51 tube condenser mic is their first attempt at catering to those with less money to spend, but who still want that high-quality Telefunken sound.Part of the R-F-T Series of microphones, the AR-51 is an affordable solution that delivers amazing tone and ultimate application flexibility at a price anyone who is serious about recording can afford. The AR-51 condenser mic is designed in the tradition of the classic tube mics of the past, utilizing the same circuit design as the classic Telefunken ELA M 251E.However, this Telefunken recording mic employs new cost-efficient manufacturing methods to meet a price point suitable to any recording studio, from major, world-class facilities to voiceover rooms and home project studios. The R-F-T Telefunken AR-51 utilizes only premium components, including a vintage New Old Stock (NOS) tube that has been rigidly tested for noise and microphonics, as in the ELA M 251E. The Telefunken AR-51 mic also features a globally-sourced power supply and capsule, both rigorously tested prior to installation.As with all products in the R-F-T range of Telefunken Elektroakustik microphones, the circuit board has been designed for superior current handling, permitting the amplifier to have full access to the necessary "power on demand" for handling low frequency and transient information. Modifications have been made to the Telefunken microphone's amplifier circuit to optimize the performance of the capsule and a signal path that includes the same European manufactured output transformer found in every ELA M 251 E built since 1960.At the Telefunken Elektroakustic studios in South Windsor, CT, audio engineers have successfully tested a wide range of applications for this large diaphragm microphone. The tube condenser microphone is especially suitable for recording acoustic and electric guitars, piano, and percussion; for drum overheads and close miked drums; and for both male and female vocals. The perfect complement to the company's acclaimed AK-47, the Telefunken AR-51 is a significant addition to any studio's microphone locker.The Telefunken AR-51 mic includes the sameEuropean manufactured output transformer found in every ELA M 251 EVintage New Old Stock(NOS) tubeRigidly tested for noise and microphonicsGlobally-sourced power supply and capsulebuilt since 1960Suitable for many miking applicationsShock mountWooden box |

Sterling Audio ST66 Large Diaphragm Tube Condenser Microphone $363.99 The Sterling Audio ST66 is a tube condenser microphone that employs a large capsule with an ultra-thin 3-micron evaporated gold Mylar diaphragm. Optimized to capture the most definition and detail from all acoustic instruments like piano, drums, and guitars, the ST66 mic's low-noise GT6205M tube in a Class-A triode circuit provides warmth and detail, adding new dimension to vocal and especially instrument recording. The ST66 uses triode wiring on specially selected pentode tubes to yield low noise and a more realistic dynamic response than their competitors. Its power supply is designed with a load-balancing circuitry that allows cable runs of more than 200 feet with no deviation from optimal performance. Sterling Audio microphones employ several advanced technologies that separate their large-diaphragm condenser mics from the rest of the pack. One of the more important advancements is their Disk Resonator system. With it, Sterling Audio is uniquely able to compensate for the 14kHz frequency roll-off that is inherent in large diaphragm mics. As any good audio engineer knows, this deficiency translates to a lack of sparkle from high-frequency sound sources. Other manufacturers have typically solved this problem by cutting other frequencies and then increasing the entire signal to help even out the frequency range. Unfortunately, this results in increased noise. Disk Resonator Technology incorporates a brass umbrella that protrudes from the center of the diaphragm in Sterling Audio's ST66 microphone. It gently boosts the diaphragm sensitivity to shorter sound waves, allowing it to respond more accurately to those all-important higher frequencies. The result is optimal sensitivity, full frequency response, and a low signal-to-noise ratio. Another piece of audio wizardry comes in the form of the ultra-thin diaphragm membrane made of Mylar. While most modern condenser diaphragms are 6 to 12 microns in thickness, Sterling Audio, in association with 3M, has produced a highly resilient Mylar that measures a mere 3 microns. This allows the ST66 to deliver an extraordinary degree of sensitivity. Requires phantom power. |

A Deareating Feed Tank (DFT), often found in steam plants that propel ships, is located after the main condensate pump and before the main feed booster pump.
From the theoretical Rankine cycle diagram, there are four main processes, or steps:
1 to 2 Water is raised from a low pressure to a high pressure (Pump work in) (feedwater pump)2 to 3 Water is heated to boiling (Heat input) (steam generator)3 to 4 Steam is expanded in a turbine (Work out) (turbine)4 to 1 Wet vapor is condensed (condensing) (surface condenser)
In the practical implementation of a Rankine cycle, it is common to break the single pump (process 1 to 2) into three pumps: (in water flow order: condensate pump, feed booster pump and then feedwater pump). The DFT has three purposes:
1. Remove dissolved oxygen (ir) from the condensate2. Pre-heat the feedwater3. Provide a storage/surge volume
Discussion:
1. Dissolved oxygen is removed by injecting auxiliary exhaust steam into the upper portion of the tank (above the feed water level) in roughly the same location (elevation) as the condensate is brought in at. The two are put in close physical contact over a large surface area to maximize heat transfer. As the condensate is heated the steam drives off any dissolved gasses. Since the steam is injected above the feed water level a steam blanket forms above the water to keep the non-condensable gasses from re-entering the feed water. There is a connection to the gland exhaust system on the upper portion of the DFT that withdraws the oxygen and other non-condensable gasses as they are driven from the condensate. The reason from removing the oxygen is to minimize corrosion and improve the vacuum quality.
2. The steam heats the water in the tank
3. The water in the tank serves as a surge volume within the steam plant.
Why a surge volume?
This allows for the plant to change bells (power output level) without running the feed pump dry or flooding the turbines. Consider the plant running in a steady state condition.
The bell is increased, more power output demanded, the rate of feed is increased. This draws more water from the condenser, perhaps to the point of being dry and starving the boiler and causing a loss of propulsion. This is until the water is converted to steam, provides its energy to the turbine and then is condensed in the condenser.
The bell is decreased, less power output demanded, the rate of feed is decreased. Since less water is drawn from the condenser the condensate level rises, covering more condenser tubes, reducing the ability of the condenser to maintain vacuum and if the level is allowed to go high enough vacuum could be lost and/or water could impinge (and damage) the turbine blades as the turbine normally sits directly above the condenser.
