Lula,
The chassis is 18.5" wide X 13.5" deep x 3.5" tall, with the power transformer sitting about 4.5" above that (with the tops of the 300B’s extending above those about an inch). Weight is just under 55 lbs unboxed- closer to 60 lbs packed. The amplifier uses two 5U4 rectifier tubes and independent transformers for each circuit in the unit. Best, Aric
