L.E. with 117 V

powering)

Check power source.

(external to unit)

Does the amplifier

use a 117 V power

supply?

Raw DC

voltage within

specified

range?

Yes

B+ voltage

within

specified

range?

Replace the H.E. power supply

(if present) or the RF module

(for units with linear power

supplies).

Replace the main fuse. If the fuse blows again,

replace the H.E. power supply (if present)
