Do you like FAT mids and a little extra high end sparkle? This is our ECC803S V1 Option Retube Kit for the Bad Cat Lil 15 Heads and Combo Amps. It uses a long Plate ECC803S for V1, a current balanced ECC83S for the phase inverter and an EF806 to replace the EF86 in V2. The default power tubes are a matched pair of the JJ EL84's. With the Customize option you can configure this kit to use the JJ EL844's which will drop the power output a couple decibels (ideal for players wanting decreased headroom/output).
