Jet City 20H and 20HV High Gain Option

Product Details

Want all the gain you can get? This is our High Gain Option Retube Kit for the Jet City 20H and 20HV Amps. It uses three handpicked High Gain ECC83S's with one being current balanced for the phase inverter in V3. The default power tubes are a matched pair of the JJ EL84's but you can configure this kit to use the JJ EL844's to drop the power output a couple decibels by clicking on the "Customize" button!

The Balanced High Gain ECC83S is located in V3 closest to the power tubes.

These amps are adjustable bias. All you need to check and set the bias is 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.

EL84's should bias up to between 22 to 26 mA per tube.
The JJ EL844's are a 9 watt tube and should bias up to between 16 to 20 mA per tube.
