Valab 640H Grid Choke for Tweak Modify Your Tube Amp 1200H grid choke:What is a grid choke? It’s a long story, and you can find a lot of detailed information online. In brief, a grid choke is: A high-inductance coil that provides extremely high impedance to AC signals while maintaining very low DC resistance. Why is it used? In every tube amplifier, and with every tube, you will find a grid resistor—typically 50kΩ or 100kΩ—connected to ground. The grid resistor provides a reference voltage for the grid. A grid choke is used as a replacement for this resistor. Does the grid resistor affect sound quality? In most designs, the grid resistor seems insignificant, and it’s true that you won’t hear much difference when replacing a cheap resistor with an expensive one. However, replacing the resistor with a grid choke makes a big difference. You may be surprised by how much musical information is normally lost. A grid choke presents very high AC impedance, preventing signal loss, while its low DC resistance provides the grid with a stable reference to ground. ✨ Features of the VALAB GC1200-5 Grid Choke High-grade thin permalloy nickel core lamination 5N oxygen-free copper wire used for coil winding 14,000 turns, generating 1200H at 120Hz and over 6000H at 20HzDimension : 50 x 45 x 45 mm, mounting legs do not included. Mounting holes distance is 60mm. ✨ Why it matters A grid choke may look small and simple, but it is far from a cheap iron part. It is an expensive component typically found only in high-end tube amplifiers. When installed in your amplifier, it can bring remarkable improvements in headroom and detail, especially in the high frequencies.We believe audio should be effortless and musical, without harshness or fatigue.This choke is engineered to support that philosophy, offering q quiet, stable foundation for great audio. Experience a quieter, cleaner, more musical tube amplifier.This choke delivers exceptional noise reduction and dynamic stability, revealing more detail, depth and natural tone.Upgrade your supply, upgrade your sound.The price $100 is for one pair, two chokes.
