MRF134s are pretty available.  Usually under $25.

>>> In the PRS10 the lamp is exited by a strong RF field @ 150Mhz
>>> this is generated by an MRF134 within the lamp package
>>>
>>> The failure mode was caused by the growth of a substantial tin whisker
>>> within the lamp assembly which appears to have killed the MRF134.
