    My M125 mono block build

    Post by thompson12 on Sun Jan 17, 2016 5:25 pm

    Hi all here's my M125 mono block build, I didn't figure out how to post pics so here's a link where I have them posted

    http://emotivalounge.proboards.com/thread/44643/mono-blocks?page=3

    And then the miss hap,

    I though I lost one amp Just got new driver tubes to try diferent sounds, swapped out new driver tubes not even ten minutes on them and down comes a snow globe right on top of the amp. >Very Happy . I've played louder and longer before with nothing moving on the speakers I always watched. This time I'm not paying any a tension to it and smash. It must have bin the diferent tubes with different vibrations (puke)

    Broke down the amp quick for a look see, nothing appears to have gotten wet. I Vacuumed it and blew it off with air anyway.

    I'll let it set till tomorrow and then take two of the power tubes out of the other amp since they only Need two to work and then make sure everything is Ok.


    Five of the six tubes busted, Around $300.00 dollars in tubes gone (puke)

    Just ordered new driver tubes won't be here till the end next week

    I'm not sure I understand what exactly happen I read the description from the other link small glass pieces that shattered and went everywhere? What? "Water" got on your tubes somehow? What?
    What tubes were you using and what did you change to?
    Did you remove tube with the amp powered up?
    Please share very specifically what you did that lead to this unfortunate event with your amp.

    "Snow Globes" are those decorative glass globes with liquid in them.  When you turn them over, particles inside look like snow falling.

    NOT what you would want in your amplifier!

    That particular snow globe must have had a bad attitude.

    The VTA M-125 > "Takes a lickin' and keeps on tickin'" (from the old Timex commercials of long ago). I had a customer forget to turn off his pair of M-125's before he went on a week's vacation. He came back a week later and both amps were still sitting there glowing .. He Emailed me and asked if any harm was done? I told him that other than an extra 168 hours on the tubes and a slightly increased electric bill for that month, the amps would be OK ... Lets see .. each amp about 250 watts at idle = 500 watts X 168 hours = about 84 extra kilowatts on his bill ...

    My girl Friend had a Christmas snow globe (they are a ball filled with water and fake snow) on top of the speaker. I listened numerous times with it up there with no problems.

    Well I got new driver tubes to try so I put them in the amp and listing less then ten minutes when the snow globe came crashing down on top of the amp that's where the glass and water came from.

    These are mono block amps so I took two of the KT120'S out of the other amp and tried it in the amp the next day after I was sure the amp was dry.

    No I did not remove the tubes with the amp powered up I flipped off the power switch and unplugged the amp as I didn't want to light up like the Christmas tree

    That was my attitude towards the snow globe

    Glad to know the M125s are so tough. I've only had a couple mishaps over the last 5 or so years - mostly due to weber rect failing - I'm using the phillips rectifiers - been running fine for the last 3 years.
