Floyd -
Now that's a mean thing to say! :-)
I used a VF-1 for several years handling traffic on CW, (very picky ops
re signal quality, especially high speed,) with no problems. See
January 2008 ER.
There ARE several identified ways for the VF-1 to go astray however,
aside from the obvious quality kit assembly / soldering.
One, it needs it's own regulated power supply, no "borrowing" power from
the transmitter.
Two, it needs a GOOD "selected" 6AU6A, or better still a 6AH6.
And, "C", it needs a reasonable (30 min) warmup.

Why there are any VF-1s left on the planet is a mystery to me. I
owned a couple of them, beginning in 1959, and they were absolutely
dreadful. Guaranteed to drift and chirp. You could always tell who
was using a VF-1 when you heard the CW signal. The Eico 722 was a
good stable VFO and I still run into one of them from time to time. A
pair of VF-1s make a nice set of nostalgia bookends, but that's about
the extent of their usefulness.

Subject: [Drakelist] Drake 2-NT to Heathkit VF-1 VFO
I'm looking for a VFO for my "new to me" 2-NT. I've read where
several older VFOs will work with some modifications, mainly
converting to grid block keying. Has anyone had experience with the
old Heathkit VF-1? I believe it has to be modified for grid block
keying but I'm not exactly sure how to accomplish that. I also
understand that they are known to drift a lot. Could that be
somewhat remedied by replacing some of the components with newer ones?
TNX in advance for any advise!
