I've finally finished this combo after working on and mostly off for a year and a half. It has 60 watts with 1x15. The original speaker is a Quam Nichols (I'd never heard of prior to this) that I had rebuilt and had the amp gone through too. For unknown reasons, the rear panel was not made to cover the entire back opening. After doing a little experimenting, I discovered that it sounded much better with a completely closed back, so I made a panel to close up the back and added some insulation. Sounds decent for what it is, particularly with an active bass. It was in good physical shape and turned out nice with a good cleaning and rehab.
