Plate choke designs This webpage is protected by HTMLProtector Plate choke design By Matt Erickson, KK5DR. (Revised, 2012) Traditional design: The plate choke, as used in an HF tube type amplifier in this article. The plate choke is a device which serves the purpose of feeding the DC plate current back to the HV power supply, while blocking

Audio chokes can be built to customers specifications, within reason. Available in open frame or vertical mount. Nickel trim for inductance enhancement available depending on lamination size. Low capacity plate-side winding. Balanced or center tapped designs also. The current through the reactor will determine the inductance needed at 25 Hz for ...

RF Plate Choke – W8JI Website

The RF plate choke must have several thousands of ohms when the amplifier uses high voltage tubes. RF plate choke impedance must be high enough to limit RF choke current to safe values. A conservative RF current estimate would be E/Z=I where E is DC plate voltage and Z is choke impedance. A 200 uH choke on 1.8 MHz only has about 2600 ohms

The PRC-3 audio choke from One Electron was designed as a plate load for the output of either a high quality line amplifier or a phono preamp. Since the plate can swing up to double the B+ value, a high output voltage can be attained with relatively low B+ values.

Chokes, mostly used in tube amplifiers. We have a wide range of chokes and inductors for tube amplifiers, ranging from anode choke LL1667 (operating current from 5 mA) to filament current choke LL7233 operating at 3.4 A. Our chokes are built in our dual coil single C-core style. The use of C-cores with well-defined air-gap results in an almost ...

I don't know if placebo effect or not, but my amplifier sounds better if I insert a parallel LR filter in the anode path, just before the usual plate resistor. This is called RF anode choke or "parasitic choke". Usually I read in radio schematics anything above 1mH should work to purge possible...

McIntosh Plate Chokes. I recently restored a McIntosh MI-60 amplifier (similar to a MC-60). I. chokes looked a bit toasty. The instruction manual didn't identify the. Internet. My chokes look like ordinary molded inductors, with a. mottled brown and green body about 1/4" in diameter and 3/4" long. I removed the good choke and measured it on my ...
