This is a rare and unique amp, as it features the full "true stereo" configuration, with dual output transformers. This would have been a flagship model from 1966, chop full of features like 2 channels + reverb and (stereo) tremolo. The amp has received some minimal servicing, by way of a changed power cord and newer power tubes. One of the output transformers has been changed, and one is still original. It still has the original Jensen C12PS, which sound fantastic!
