Have no clue what that should supposed to do.

That 1k is grounded when unit is OFF.
So becomes useless when in OFF state (For moment I though its for the on/off "Plop"reduce)

Wire after 1k (27V, Cass Pin 3 and E60 in that way you short out that 27E resistor at any time.

Then this way, you put an extra half way rectifier across the bridge rectifier.
I don't get it.

Looking at my 22RH953 there is nothing to be found about that extra PCB.

At moment I can't find a Service-anouncement about this.
As many after market or during production a lot of remarks or changes made
are been sent out to dealers/Service shops.

E5/E6 is the switch to get power to the Tuner.
Its the Tuner On/Off switch.

So have no clue why this PCB is in it.
If you keep having trouble with it, just take it out.
My idea.
