    hi fellow Amp Heads,

    I was just wondering about the consensus of amp makers who prefer using Heyboer versus Mercury, Hammond etc. xformers; Is there an audible difference? Is one any more reliable than the other?

    Thanks,

    MG

    yes there is an audible difference. Between quality ones like Mercury and Heyboer, exactly how MUCH audible difference is up for debate.

    And really, tone is subjective.

    +1 what OTM said.

    Also, even trannies of the same mfg will sound different.

    In one of my amps I can switch output trannies between a MM Plexi
    and a MM JTM45. The difference is more then just subtle, it is
    VERY noticable.


    Enjoy

    Also the difference between a cheapo reissue tranny and
    a high quality MM tranny is HUGE!

    I guess you can tell I like MM trannies, they r a w K :dude:dude

    The output transformer is a huge part of the overall tone and dynamics of an amp.

    I prefer MM because:
    a) I've been doing business with them for a long time
    b) They tend to over build (better thermal performance)
    c) I can call up and they'll wind anything I want. Sergio is a genius.

    there is a substanitial difference in price between the two when you get to mutliple piece pricing. I won't say you can/could hear a difference at twice the price...
    I like the merc mag iron I've not had a single problem with one (except a non paying customer..not their problem). I've not talked with Sergio but have had Paul reply to my order from his vacation in hawaii which I thought was the extra mile.

    All transformers sound different. There are many variables in the design of audio transformers and plenty of tradeoffs too. If you really want to learn about them Google on terms like "bi-filar wound" etc. Whether a good hi-fi transformer a good guitar transformer makes is a point of some conjecture. :)

    Generally you want a transformer that can serve up the power very low in the audio spectrum (this is where testing for max output power at 1kHz can be misleading). This is generally achieved with lots of windings and a big chunk of iron - and these obviously increase costs. Much more here but others can explain a lot better.
