Bogner Duende High Gain Option
Product Details

Want all the gain you can get? This is our High Gain Option Retube Kit for the Bogner Duende. The preamp section uses a standard ECC83S in V4 along with four handpicked High Gain ECC83S's with one balanced for the phase inverter in V5. The default power tubes are a matched pair of the JJ 6L6GC's along with a JJ GZ34 rectifier tube, however you can configure this kit with a JJ 5Y3S rectifier tube for lower power or choose the JJ 5881's or the JJ 6V6S's by clicking on the "Customize" button.

The Balanced High Gain ECC83S is located closest to the power tubes in V5 and the standard ECC83S is located in V4.





These are all 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. You can find all these under the Related Products Tab. 

You can use our Generic Bias Video for reference.

The video below explains the difference between bias probe types.
