This is the low powered corner where I keep all the info on the 4 watt amps. These amps use a power stage consisting of a pair of 6ak6 7-pin miniature pentodes in a push-pull pair. Big pentode punch in a small package.
You can see the power tubes here on the left. They are smaller than a standard 12ax7 preamp tube. Big power in a little package!
These amps usually come in a smaller head shell 20" wide but can be put in any size head cab if desired.
These get the oversized (20watt) custom made EDCOR transformers wound to my spec for these tubes.
