ic5 help

pick up a 148 gtl side mike made in Taiwan on trade it seems someone tried to do wide banding on ic-5 r190 suppose to be 100ohms is like a 47k
on top of the solder side of the chip looks like a 100ohm resistor i put the100ohm back in r190 like the schematic shows and remove the one on the solder side but know it has low power maybe a cap change also ????

now it has low power

Did it used to do more power? Or was it this way all along?

that's the way i got so i put r190 back to 100 ohms and remove the other resistor when i tune L48 the power came back it's still doing the same watts but it's back to stock i was thinking of replacing the driver 2sc2166 with a 2sc1306 to see if gets a tad more out I'm only seen 14pep all limiters are intact

I have the vague recollection of the 2166 being a little hotter than the 1306.

Can't remember comparing them any time in the last few decades, could be remembering wrong.
