What year is my VH4?

[Jimco]

Hello, I’ve searched around on the boards a little bit but have been unable to find this topic. If it exists already can someone please direct me to it? Question: How can I tell what year my VH4 was manufactured? I love the amp and have change power tubes and pre-amp tubes and have re-biased it for the new power tubes, so I’ve been inside of it.
Thanks

The first two digits of the serial number correlate to the last two digits of the year it was produced.

99=1999
00=2000
04=2004 etc.
