Hughes & Kettner Trilogy ECC803S V1 Option
Product Details

Looking for a vintage vibe with FAT mids and a real sparkle? This is the ECC803S V1 Option Retube Kit for the Hughes & Kettner Trilogy Heads. It uses a Long Plate ECC803S for V1 along with three ECC83S's with one being current balanced for the phase inverter in V4. The default power tubes are a matched quad of the JJ Electronic E34L’s but you can configure this kit to use the JJ EL34II's, EL34’s, KT77’s or Big Bottle 6CA7’s by clicking on the "Customize" button!

The Balanced ECC83S is located in V4 farthest from the input jack and the ECC803S is located in V1.


These are adjustable bias amps and if you use the HK shunt method to measure bias all you need is a Multimeter. This method is a bit tedious to say the least, it's much easier, more accurate, and more convenient to use a bias probe and a Multimeter or our all-in-one "Pro One" bias probe that reads both the plate current and the plate voltage simultaneously. These are available under the "Related Products” tab.

You can use our Generic Bias Video for reference.

The video below explains the difference between bias probe types.
