I'm also a Telewave Dealer... The answer depends on the generation/age and specific model of your Telewave Multi-coupler. Some have/had bipolar transistors, some had special what I call quasi low noise FET type devices and I believe some of the newer Telewave Preamps should now be using Phempt devices.
Your best bet would be to open it up and snap a picture to share with whom ever helps you find the replacement device. cheers, skipp skipp025 at yahoo.com > "Joe Burkleo" <[EMAIL PROTECTED]> wrote: > > Anyone know the correct part number and a source for the FET's that > Telelwave uses in their TWR series of multicouplers for 150 and 450? > > Thanks, > Joe - WA7JAW >
