this is from a Roland Bolt 60 guitar amp,

has a fet preamp and a tube output

did not dissect, used PRR method to get turns, plenty of room in the window for passing wire,

do not know who made it, lams seem to be metric but close to 100 EI,

running lots of Gauss to make 60 watts

probably closer to a 40 watt amp,

here is the print>
