MRF486 alternative
trying to resurect a damaged FT1000 which seems to have a damaged PA, looks like r08 and r09 are burnt out, whilst its in bits I want to replace the drivers which are MRF486 but I cant seem to find an equivilant online and I was wondering if someone would be kind enough to point me in the direction of an alternative ?

Re: MRF486 alternative
Thank you for replies, spoken to eleflow and it's not something they can supply, Pete have you bought from this supplier as I see they are incredibly cheap but I am a little wary after reading horror stories online about ppl using fakes from China?

I'm in the same boat, can't find any alternative for the FT-1000 finals.

Re: MRF486 alternative
Eleflow is a China based company and not a semiconductor manufacturer with a R & D department. The 486 datasheet is just a copy & paste from the Motorola data manual. Not they do not bother to replicate the impedance, gain and power plots. Save your money. I'd like to suggest a post on the FB Yaesu group: https://www.facebook.com/groups/33717530697/ or eham.net forum to find a NOS source or a suitable alternative.
