Hi Mark,

If they specified a VTVM it was probably because they thought the input 
resistance of a traditional VOM, 20,000 ohms per volt, would load down 
the circuit too much to get an accurate reading. Fortunately, modern 
digital multimeters, even the 3-dollar ones from Harbor Freight, are 
equivalent to VTVM's.  It takessome mental gymnastics to make up for the 
lack of a swinging needle when peaking an adjustment, but it's just 
annoying not impossible.

Go for it,
Al
