Diamond Spitfire Gold Pin Option
Product Details

Want a really smooth and rich tone with less grit? This is our Gold Pin Option Retube Kit for the original Diamond Spitfire Amp. The preamp section uses four Gold Pin ECC83S's with one balanced for the phase inverter in V4. 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 or Big Bottle 6CA7’s by clicking on the "Customize" button!

The Balanced Gold Pin ECC83S is located in V4 farthest from the input jack. 



These are adjustable bias amps. 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, EL34 II'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.
