The amp is in really good shape for a 52-year old amp. It sounds great, and can give you that sludgy, doomy Sunn tone that people associate with the Model T, but at a more manageable volume.
It has been upgraded to a three-prong grounded plug to prevent shocks that old amps can sometimes deliver.
The reverb is a bit wonky. It could probably use a new preamp tube for the reverb circuit. The tremolo is super choppy and unique.
I hate to get rid of it, but I have too many amps these days.
