Looking for a vintage vibe with FAT mids and a real sparkle? This is our ECC803S V1 Option Retube Kit for the Bugera 1960 and 1960 Infinium Heads. The preamp section uses a Long Plate ECC803S for V1 along with two ECC83S's with one balanced for the phase inverter in V3. The default power tubes are the JJ Electronic E34L’s but you can configure this kit to use the JJ EL34’s, EL34II's, KT77’s or Big Bottle 6CA7’s by clicking on the "Customize" button.
There are two versions of this amp, if your amp is the "Infinium" model them it is self biasing and will set whatever tubes are installed right at 30mA per tube. This is a little on the cold side but sounds OK.
The non-Infinium amps are adjustable bias amps and all you need to check and adjust the bias is 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 the "Generic Bias Video" we made using a Marshall 800 for reference. The video below explains the difference between bias probe types.
