Marshall 50 Watt 800 2 Channel 6550 Amps Standard Retube
Product Details

This is the Standard Retube Kit for the Marshall 50 Watt 800 2 Channel amps with 6550's. The preamp section uses five ECC83S's with one balanced for the phase inverter in V5. The default power tubes are the JJ Electronic 6550’s but you can configure this kit to use the JJ KT66's or KT88’s by clicking on the "Customize" button.

The Balanced ECC83S is located closest to the power tubes in V5.


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 the "Generic Bias Video" we made using a Marshall 800 for reference. 

The video below explains the difference between bias probe types.
