    Hi all, I am from Vietnam, do have a pair of VAC V100 as well.

    Having recapped all about 60 capacitors, added volume attenuators and made cages for both blocks. They are fantastic to drive any low efficient speakers.

    A little bit strange that my pair has switches that change modes of power supply transformer.
    Some pairs optioned by VAC with knobs switching between triode - ultralinear, cages also.

    Pics for fun:

    Welcome to AK Dotting and nice job with your system and amps.

    The manual says you can have that switch installed if you send it back to them.

    Can somebody here help to clarify the differences between two versions MK1 and MK2?

    Many thanks!

    I wish this company had some chronological order to there equipment and dates when gear was in production. It's so hard to find any info on their stuff.

    They are great when you call them. Kevin, the owner answered when I called and spoke to me for 30 minutes about retubing my Pre.

    They're not much for documentation on old products- but Kevin has a memory like an elephant about all his old gear. A call to him can reveal a lot...

    Regards,
    Gordon.

    In fact I have both versions, one is with MKII written on the faceplate, the other without.

    So far I failed to communicate with VAC twice asking technical and spare part questions by emails to the official address then received no reply.

    Besides, I am too far to make a call to Kevin. Will very much appreciate if someone can help it :beerchug:

    See below pic for MKI version:
