Hi all - this is my first post, so be gentle with me
I have a GME Electrophone black model TX830N (26MHz for New Zealand legalities) with a blown final transistor (2SC2078) due to a broken antenna.
I have access to a 2SC1969 transistor that I would like to fit in place of the C2078 that I don't have. I understand that this is a drop-in, but what else do I need to tweak?
I have a circuit diagram for the TX830N, but I'm not sure how to read it exactly.
I also have the use of a Hewlett Packard RF communications test set, though there is no one who can tell me now to drive the thing. I can switch it on and find the screen that tell the Tx frequency and power easily enough... Is it necessary to attach a load when using the test set, and if so, how?
I'm sort of a newbie when it comes to fiddling inside radios, though I've built hi-fi equipment before. Can someone give me a leg-up? Thanks!
