What Anode choke is? It is long story, detailed information you can get from Dr.Google. In brief, anode choke is: 1) A very high inductance coil which supply extremely large impedance to AC signal but low DC resistance. 2)Where it is used? In every tube amp, actually for every signal tubes, all need one large 'plate resistor', generally 3 to 7 times resistor value larger to Rp(plate impedance). Plate resistor give isolation of power filtering. 3) Plate resistor generate very large voltage drop and heat! It bring heat stress in you tube amp which decrease life span of many parts inside your tube amp.  And you  waste  so many energy here!4) While, if you change plate resistor with plate/anode choke.  You will immediately increase significant headroom and decrease energy waste in heat generation. More driving power, more detail  and  more reliable circuit. Features of Valab AP200-35 Anode choke * 50% Nickel iron + 50% Z6 silicon iron  lamination. * 5n oxygen free copper wires was used in coil wiring. * 14000 turn coils, generating 200H at 120Hz and over 1100H at 20Hz.*2330Ohm DC resistance * Anode/plate choke, look small and simple, but not a low cost iron part! Actually it is a very expensive part only used in most high grade tube amp. When you install it in your tube amp, it will bring you incredible improvement in headroom and detail. Query Google, to see how best tube amp use it!The price $80 is for one pair, two chokes. We use EMS air express for International shipping. Shipping fee to US and Europe is $35usd, to Australia, Asia is $25. It is insurance included and you can track your parcel on-line. It will take 5~7 working days to delivery your order to your home. We accept custom order anode/plate choke design. you can order 'any' inductance value,  fell free to sent message to me for your requirement.Feedback Reviews Listing:Excellent product and service. these arrived from TW faster than many US orders    200H anode plate choke 6sn7 6j5 5842 5687 12au7 12AT7 (#300162224651)Very good and nice chokes, very prompt shipment.
