Orange OR50 Gold Pin Option

Product Details

Want a very rich and smooth tone with less grit? This is the Gold Pin Option Retube Kit for the Orange OR50 Amps. The preamp section uses three Gold Pin ECC83S's with one balanced for the phase inverter. The default power tubes are a matched pair the JJ Electronic E34L’s but you can configure this kit to use the JJ EL34II's, EL34’s, KT77’s or Big Bottle 6CA7’s by clicking on the "Customize" button.

The Balanced Gold Pin ECC83S is located farthest from the input jack.

These 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. The E34L's, EL34II's, EL34's, KT77's and 6CA7's all bias the same.

You can use the Generic bias video we did on a Marshall 800 and the procedure is the same.

The video below explains the difference between bias probe types.
