I have a few ideas but I may be wrong. What would be a good replacement part for a 2SB824?
Yes Andy this is a Realistic TRC-485 almost the same as a PC-122I hear ya!
Was just saying the TO-220 types have only so much wattage they can dissipate - the TO-3P and the 247 styles have the bigger die surface area to drain off the heat.
The problem is with the radio - not the part = the size needed to upgrade versus the amount of room the radio actually has for that.
A TO3-P Flat pack is a big transistor - can't squeeze them in too well on a PC-122. At least not without several extensions ...
Hey, as long as you got room!
