Wolverine 50 (2004)

2004_wv10
The Wolverine was designed to be an aggressive single-channel high gain amp. Capable of a more modern sounding distortion, it also achieves nice rock overdrive/distortion with the gain turned down. The preamp section uses four 12AX7 tubes (one is for the phase splitter section), and the output is approximately 50W (class AB) using two EL34 output tubes. (The 50W Wolverine was built using the same chassis and enclosure size as the 10W Wolverine.)

Front panel controls

Low, Mid, High knobs to shape the voicing of the EQ.

Master Volume control for the overall volume of the amplifier.

Gain control for the overdrive/gain level.

Rear panel controls

8/16 ohm impedance selector switch, two parallel output jacks

Bias test points (two red pin jacks and one black pin jack)

Bias pot is accessible through the top of the chassis near the back.

Tubes

4x 12AX7 preamp tubes

2x EL34 output tubes

This amp may also use 6L6, KT66, KT88, 6550, 6CA7 as the output tubes–if the bias range will allow for it–this amp was primarily intended for EL34 types, so its bias range might not accommodate many tube types. Keep this in mind when biasing the amplifier.

When changing output tubes, bias the amplifier as per the “biasing your Peters amplifier” instructions.

Removable protective bar

The metal bar on the back of the amp uses two thumbscrews to hold it in place.

Fuse ratings

Mains = 2.5A Slo Blo

HT= 300mA (1/3A) fast acting

Both fuses should be rated for 250V.

Note: This document refers to the 50W Wolverine model only. There was a 10W Wolverine model which had different features/specifications as well. Do not use this document as reference for the 10W Wolverine model.
