Hi,
I am doing a tune up on an old turntable I have and according to the
service manual I need to make measurements with a VTVM (vacuum-tube
voltmeter). I own a Fluke 111 DVM, is there any reason why this can not
work in place of the VTVM.

No. They didn't have DVMs when that service manual was written!

It doesn't even make sense why they'd specify a VTVM, given that turntables
are mechanical devices.

Oh, I suppose it's one of those new-fangled turntables that have electronics
to drive the motor in them, and they specify the VTVM so as to not load
down the voltages when measuring.
