Do you like FAT mids and some extra high end sparkle? This is our ECC803S V1 Option Retube Kit for the Bad Cat Alley Cat Amps. It uses a Long Plate ECC803S for V1 and an ECC83S for 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).
