Bugera 1990 Gold Pin Option
Product Details

Want a very rich and smooth tone with less grit? This is our Gold Pin Option Retube Kit for the Bugera 1990 and 1990 Infinium Heads. The preamp section uses three Gold Pin ECC83S's with one balanced for the phase inverter in V3. The default power tubes are a matched quad of the JJ 6L6GC's. However you can select a quad of 5881's, EL34's, EL34II's, E34L's, KT77's or Big Bottle 6CA7's by clicking on the "Customize" button! 

The Balanced Gold Pin ECC83S is located closest to the power tubes in V3.


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.
