VCR transformer hum

    It looks like my VCR will be going back 'somewhere' to be repaired

    This time, while it's being repaired, I'd like to silence a
    transformer hum that I've noticed for a couple of years.

    It's not very loud at all, but I can hear it when the machine is not
    playing, just plugged in.

    My questions. Will a good new transformer in a quality machine (mine
    is a $600+ JVC) make any audible noise?
    If not, how much would a new replacement transformer cost and would I
    have any difficulties getting one for a VCR that's well over ten years

    i would put rubber mounts on the transformer, to absorb the sound before it
    amplifies to the plastic
  3. Any replacement is likely to be from a junker and may have the same
    problem. It may be possible to silence yours with varnish, or as
    someone else suggested, rubber mounts.

    Mine is a quality VCR built maybe 10-15 years ago. The chasis is all
    very sturdy metal.
    As a matter of fact, I was going to pick up a spare cheapo VCR (~$70)
    a few weeks ago to save wear and tear on my good one.
    When I plugged it in and played a couple of tapes I knew it was going
    right back to the store. The cheapo plastic chasis hardly contained
    any transport noise. Man was it noisy compared to my old one!

    I guess I can try rubber mounts in any event.
    BTW, I once wrapped a stereo amplifier transformer in towel to dampen
    its growing hum. Would this harm the amp, transformer?
