Driver / final bias spec President Lincoln

[Jericho]

I've got the version that came stock with the MRF455 and I'm looking for the correct specs. The patient has 65mA between TP4 and TP3, and 110mA between TP4 and TP2.

Combed through there, nothing exclusive to the president lincoln though unfortunately Like the HR2510's the earlier lincoln had a 477 0r 497 final which I believe were set at 50ma like rogerbirds page states, but I believe it's different with the totally different newer MRF455 found in the latest lincoln model. I could be wrong?

I was wondering if I could use that 85mA value from the 455 mod.

Thanx

That's what I did on my 2510 w/ a 455 swapped in
