Hello ---

The FM Booster circuit shows two  BF 494 & 495 colpits oscillator pair
transistors --

As the BF 495 is virtually impossible to find  (takes months to import)

can that transistor be substituted  ,    using   a BF 199 or another BF494?

(SEE attached circuit below )

will be grateful for any sage advice --

fm booster is  fm antenna amplifier ..right?
yes you can use two BF199 or two 2N9018 or
2SC3355 or maybe if you have
BFR91A - which is a great VHF/UHF transistor used
in many antenna amlifiers !
