never torched a Partridge, always wanted to, hard to find,
especially the C core models which may or may not have been used in the earliest Marshalls.
but we did find this on youtube , has UL taps at 75%

can't vouch that is an actual partridge, and have not built it yet, but anything is better than nothing,
looks like a good design, so we wrote it up>
