Hi! I purchased my VHT Pitbull 100CL second-hand in the mid-2000s, and I would greatly appreciate it if you could provide the year of manufacture. I’ve included the serial number below:
I still love this amplifier, and I think I’ll never part with it. 
Welcome to the forum!
That looks like a nice clean one.
It was built in May 2002 and is a 230V model.
Cheers,
Dave

I love this amp and I’ve been using EH EL34 power tubes for quite a few years now, and I’d like to try something different. Do the Shuguang EL34BSTR work well in this amp? Those are the ones I had in mind.
