Peavey XXX Low Gain Option
Product Details
Want to tame the gain down a bit in the second and third channels? This is the Low Gain Option Retube Kit for the Peavey XXX. The preamp section uses a standard ECC83S in V1, two ECC832's in V2-V3 and a current balanced ECC83S in V4 for the phase inverter. The default power tubes are a matched quad of the JJ 6L6GC's but you can configure this kit to use the JJ 5881's, EL34II's, EL34’s, KT77’s, Big Bottle 6CA7’s or even an Integrated Quad option by clicking on the "Customize" button!
The Balanced ECC83S is located in V4 closest to the power tubes and the two ECC832's are located in V2 and V3.

These amps are switchable from EL34 to 6L6 and also adjustable bias. 

So unfortunately PV has not entered the real world yet when it comes to bias. The bias test points on these amps measure the negative bias voltage in the circuit and not the actual plate current. So the best and most accurate way to bias these amps is with a bias probe. Using the test points is a bit of a guess but it will usually get you on the outskirts of the ballpark. Please refer to the "Test Point Bias Video" which shows and describes this issue.

The cool thing about these amps is that you can use either our "Pro One" All-in-one bias probes, or one of our standard bias probes and a Multimeter to bias the amp without removing the amp from the cab. The probe will fit under one of the tubes while it’s in the cab so biasing is literally a 5 minute job.

EL34II’s, EL34II's, EL34's, KT77's, 6CA7's and 6L6GC's should all be biased between 35mA to 40mA. The JJ 5881’s bias between 32mA to 38mA. You can use the bias video we did on a PV JSX for reference.

The video below explains the difference between bias probe types.
