The Mosrite Award amplifier was a sales disaster for both Mosrite and the Ventures. This one works well but it's not something I would take to gigs as the electronics are not robust in their design and construction.  This was the problem that folks who bought one in the '60's faced.

The Mosrite Ventures Model Echo (below the amp) never went into production. It was made by the Tel Ray company. It is an "oil can" echo. tel Ray produced the same exact model on which other companies put their logos. More info can be found at http://www.geocities.com/tel_ray/home.html .
