PA Transistor for Worthing/Solent TX

Post by g8vpg » Mon Jan 09, 2017 11:41 am

The PA transistor (BLV91) for the Worthing/Solent transmitter would appear to be obsolete and difficult to source. A friend of mine has a blown one and needs a replacement. Does anyone have one, know where they can be bought, or knows of an alternative that could be used?

Hi Shaun,
The help pages for the original kits are still online.

There were three alternate devices used at the time, with slightly different bias arrangements.
