Uniden PC76 no receive?

[ChrisH367]

I have a Uniden radio that had someone with alot of watts key on the radio...now the receive is bad. Anyone know what transistor the receive is?

Thanks

it is late but it is twards the back of the radio between the two tuning cans tr7 think i beleive it is a 1764. dont quote me on that. i would replace with a 2sc2999 if you can get it. i will double check later to confirm this.

the receiver front end transistor is a 2SC1674. in most cases this device survives front end overload but either one or both of the 1N914/1N4148's short or blow open. that would be a good place to start.
