The Impact 60 head was the most common and popular model of Impact amplifiers. This version is for use with the guitar, but without the Reverb and Tremolo circuits.
It has three 12AX7s in the pre-amp & two EL34s in the power section, with transformers hand made by a local London company called Ladbroke Transformers.
The amps are handwired point to point with a simple lay out, two channels, one voiced for bass, the other for guitar. You can of course jump the channels and use both.
Sonically these amps fall in the Laney camp, on par with a 60w supergroup.
