I have assembled control, front panel and first stage of rf board.
I didn't trim the IC's leads or resistor pack's leads. I don't know why :-)
What comes to testing, I have the same "problem" with other posters
lately. If it can be called as a problem. I am not sure.

My own (SN 4759) measurements with external DMM were as follows:
- U2 pint 5 max 3.79 V
- U4 OUT 7.9 V
I understand there is no big difference between 3.80V and 3.79V.
However, when manual asks (page 47) to adjust "R1 for a reading of 3.80V
volts" it seems peculiar not to have enough adjustment scale to achieve
or exceed the required voltage.
