Carvin X100B 6L6 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 early X100B amps that came with 6L6's. The preamp section uses a JJ Long Plate ECC803S for V1 for a little lower gain with big thick mids and a little more sparkle in the highs, a standard ECC83S for V2 and a balanced ECC83S for the phase inverter in V3. The default power tubes are a matched quad of the JJ 6L6GC’s but you can configure this kit to use the JJ 5881’s by clicking on the "Customize" button! 

The Balanced ECC83S is located farthest from the input jack in V3. The ECC803S is located in V1.


Most of these amps are fixed bias but over the years many have been modded to be adjustable bias.

If your amp is adjustable bias then all you need to check and adjust the bias is a Multimeter if you use the Carvin method. For more accuracy you can also use a bias probe and a Multimeter, or our all-in-one Eurotubes "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 Carvin bias video for reference which we did on a V3.

The video below explains the difference between bias probe types.
