VHT Pitbull Fifty-twelve HELP!!!

[urkoman]

Iīve just bought this amp. Itīs the 1x12". This amp was supossed to have an A/AB class switch and a 50w/25w reduction switch. I canīt find any in the front or back of the amp. Doesnīt it have this options, is it placed in the inside or what?? Please tell me.
I donīt mind the 50w/25w, i can remove two power amp tubes, but the class switch is important for me. Apart, if the answer is "no, you canīt switch classes"... Could it be installed? I prefer A/B class much more.
If anybody could send me the userīs manual would be a great favor (bought it second hand). urkoman@hispavista.com
Thanx.

I have a VHT Pitbull head. It has a rocker swtich on the back panel for A/AB operation.

If it doesn't have the switch it is running AB. If fact, I have never even operated my amp class A- much harder on the tubes.

Hope this helps. I don't VHT has manuals on line. I didn't even get a manual with my Pitbull CL100 head.
