If I was close I'd make an appointment for a lookey. Any number of sweep tubes like 6JB6, 6LQ6, 6LR6 & the like would defray a good chunk of the $1150. When they usually sell for $25-30 a pop...they add up quickly. There's other very useful under-the-radar tubes as well...8BQ5, 10BQ5, etc. Just scrounge the right filament transformer and you're good to go.
