Anyone know what fuse rating i would need for an old Edo-Aire RT-551 radio. Its marked inop now but i still want to replace the fuse in the panel for it

Between you, me, and the fence post, I prefer breakers rather than fuses. Breakers are easier to reset while in flight than replacing fuses.

Remember to use a minimum of 3A fuses/breakers or risk loosing precious volts. See page 86 of this presentation http://aviation.derosaweb.net/presentations/#wiring.
