    Hello All
    Does the orientation of the United Transformer LS-55 matter next to the Power transformer? If so what orientation?
    Thanks

    This is a UTC factory kit amp, the MLF-500. The laminations in the LS are across the long top dimension of the transformer -

    MLF-500, you say?

    I feel like I might need a pair of those. :eek:

    They are cool for sure, I've got a trio of them. What's amazing is that they use a full-length PCB underneath the deck.

    I think this might be the first time a PCB was used in a tube amp. Here's one of mine from a long ago AK thread on oddball amps -
