Want a really rich and smooth tone with less grit? This is the Gold Pin Option Retube Kit for the Budda Mark Nason Signature Amp. The preamp section uses seven Gold Pin ECC83S's with one balanced for the phase inverter in V7. The default rectifier tubes are a pair of the JJ 5U4GB's however you can customize the kit and select a pair of the JJ GZ34's. The default power tubes are a matched quad of the JJ Electronic E34L's but you can configure this kit to use the JJ EL34II's, EL34’s, KT77’s, Big Bottle 6CA7’s, 6L6GC's, JJ 5881's, KT66's, 6550's and even KT88's by clicking on the "Customize" button!
These are adjustable bias amps and Budda has incorporated a three LED indicator for "Cold Normal or Hot" bias so all you need is a screwdriver to adjust the bias.
