Default VHF Skymaster/Masteradio D517

Hi, I posted here previously, regarding my VHF Skymaster.

I never did get round to checking if the AF116 transistors were the problem. Life got in the way etc.

Well, I now have three of these radios. A friend donated his non-working example to me for spares, and I've just bought another in very good cosmetic condition, although also non-working.

The AF116s seem like a good place to start. Substitution with an item that doesn't suffer from the tin whiskers problem seems like the best long term option.

I've seen here... https://www.electronica-pt.com/engli...ence?ref=af116 that GT322V is suitable, but can find no reference to it on this forum. Russian made, apparently.
GT322V datasheet: https://alltransistors.com/transisto...ansistor=36088

I'm a relative novice at this, although I've repaired a couple of LCD monitors with bad caps.

Thanks for any advice.
