Crate VFX50 High Gain Option
Product Details

Want all the gain you can get? This is the High Gain Option Retube Kit for the Crate VFX5112 and VFX5212 Amps. The preamp section uses four handpicked High Gain ECC83S's with one balanced for the phase inverter in V4. The default power tubes are 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 High Gain ECC83S is located farthest from the input jack in V4.

Combo amps are very hard on tubes because of vibrations which can cause tube rattle with any brand of tube. If you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings. these are available as a pair or set of two under the "Related Products" tab.

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. These are available under the "Related Products" tab.


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


The video below explains the difference between bias probe types.
