Dear Roe,

Can you please explain to me what are these terms and what they cause in terms of sound/operation.

Thanks Roe for the links.

So how much distance between OT input and output cables is adequate?

So the build continues after the turret board finally arrived (after 3 months :) ).

As Roe and others suggested I untied the OT Primary and Secondaries to avoid further problems.

I installed the HT Fuse (internal one due to lack of real estate).

I cabled the turret board as the kit instruction suggested.

I did a fit test with the turret board, so here it is:

I'll keep you posted as the build continues tomorrow.

Updates:

I changed the cable routing thru the turret board as I noticed that is the way others do with this type of board.

I also arranged the cables to their places, can somebody please check if there is any overlapping cables can cause some problems because there is so many of them :) ?

I'd minimize parallell wires, esp. the green and blue ones in the preamp and the primary and secondary of the OT

Sorry it took so long, Leonard! Your address changing, board being returned to me, and then a Customs delay really made it rough.

Wow, it is turning out very nice. Good job. We're did you get the switches? I would like to use some of those on my next builds.
