GE 3-5811b (PLL02a) weird "talkback" issue

[Uncle Ronnie 336]

i just recapped, and put in the swing mod pinned to the top of the mods page (470uf omitted) but when i hooked the speaker up, i realised that when i transmit, my mic audio blasts outta the speaker at FULL blast. looking at a midland 77-882 schematic (same chassis) but am having trouble wrapping my head around why this is happening. this radio looks wicked cool with the LEDs in er.
