Fuse blew in my N999ES Modwright PS 9.0 power supply

Can someone lead me to the correct value for that fuse? the one that blew reads type P239 E.3A/250V. It has the thick filament with a wraparound coil...I cannot find any that matches it at Radio Shaq. Is it fast or slow blow? (it seems slow blow by the element).

Whitese,
Here is a link to the Littlefuse data sheet
http://www.littelfuse.com/data/en/Data_Sheets/239.pdf
.
Looks to be a 5 x 20 mm 3 Amp Slow Blow.
I would caution you to not just buy one, throw it in, and turn it on. It blew for a reason so you should contact ModWright to discuss why and what they recommend you do to continue.
Best of luck,
Jake

If the PS is tube-rectified, it is likely that the rectifier tube is bad. If so, try a new 5AR4 and a new 3A slo-blow, long-delay type fuse. If not tube-rectified, or it continues blowing fuses, then please contact us.
Sincerely,
Dan
