Well done Alan, the shade of blue gives it away.
Ex Tektronix 545A scope, rescued from the skip at school 20+ years ago.
Stabilised ranges 100-300Vdc or 250-450Vdc, at 200-300mA (limited by regulator dissipation), unstabilised 400/550Vdc, 2x6.3Vac at 6A.
Handy compact unit, simple design and cost very little to build.
Still going strong after 10+ years.
Rob.
