When I lost the 2M section on mine Yeasu only replaced a diode. Has worked fine ever since. Repair charge was very nominal, actually much less than I expected.

The output power of my Yaesu FT-8900 quad bander has
dropped to 0.25 watts,
regardless of power setting. 10, 6 & 2 meter TX output is
nominal
(5/10/20/50 watts). Current draw on UHF TX is 4.8 amps,
again regardless
of output power setting.
The final device in the radio is a broadband power MOSFET
covering all 4
bands, so it's OK. I'm thinking something possibly opened
between the
MOSFET drain & antenna (switching diode, filter etc.), but
why would the
current be so high even on low power (low power on the
working bands is
around 1.4 A)?
