Peavey XXX 60 Combo High Gain Option
Product Details
Want maximum gain?? This is the High Gain Option Retube Kit for the Peavey XXX 60 Combo Amp. The preamp section uses four handpicked High Gain ECC83S's with one balanced for the phase inverter in V4. The default power tubes are a matched pair 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 by clicking on the "Customize" button!
The Balanced High Gain ECC83S is located in V4 closest to the power tubes.

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 in one of the 100 watt Heads.

The cool thing about these amps is that you can use either our "Pro One" All-in-one bias probes or one of our 25.00 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.
