Would you like FAT mids and a little extra sparkle in your first channel? This is our ECC803S V1 Option Retube Kit for the Bad Cat Wildcat 40R Amps. It uses a Long Plate ECC803S for V1 along with five ECC83S's with one being current balanced for the phase inverter, an EF806 to replace the EF86 in V3 and a GZ34 rectifier tube. The default power tubes are a matched pair 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!
