Why don't you ask Homemodder or OnAudio himself (its his survey). By the time you understand the answer you will be in another level

If you pay for travel I'll go

Unfortunately, I do not have the funds for this right now... Montreal is in the east of Canada and Vancouver in the west...

Would have been nice!

Do

Can 2N5401G be used instead?

The difference is Frequency - Transition 300MHz vs 400MHz

Also what are the instructions on assembling this and setting the trim pot P1?

Thanks,
