[sdiy] another year, another day, another transformer request

[Nathan Trites]

The Bel Signal DMT series is my go to for this kind of thing, you would
want MT or DMT-6-15, but I'm not sure the size would work:

In my experience though the smallest ones available end up being just a tad
too big for smaller devices like this, and I've opted to replace the
transformer/PSU with compact switchers if it's a situation where
authenticity isn't critical.

If powering the extra stuff... maybe DMT-7-15 if it fits.
