Carvin VT16 Gold Pin Option

These amps are adjustable bias. You can use the "Carvin method" with a Multimeter, or you can use one of our 9 pin bias probes with a Multimeter, or our all-in-one 9 pin "Pro One" bias probe (which reads plate voltage and plate current simultaneously). These are available under the "Related Products" tab.

You can use our Carvin bias video for reference which we did on a V3. The video shows using bias probes and also shows the Carvin Method for EL34’s and 6L6’s. Please Note; a setting of 40 to 45mA is good for EL84’s. If you’re using the JJ EL844’s a setting of between 30 to 35mA is good using the Carvin Method. If you’re using a bias probe then a setting between 20 to 24mA is good for EL84’s and a setting between 15 to 18mA is good EL844’s.

The video below explains the difference between bias probe types.
