Hi Thomas

KOAs are Ok. Many of them are made in China now so I think you can easily find cheap sources for them.

For I/V, I prefer to use things as neutral as possible. Caddock TF02 is the one I use on your kit. Vishay S102K, the bared one is another good choice. They both sound the same to me. I went for the Caddock simply because it was cheaper! Riken's sound has a distinct signature, I use RMGs only on the tube buffer board.

As for those .1% Philips resistors, I have found IRC's .1% is less noisy. For general high precision purpose, I use mostly IRC. Good price, too. .1% Philips are hard to get here.

Dear finneybear,

thanks for your advise.

For your questions I ask for some of the big dealer already.

They said most populare 1% 25~50PPM will made in China. But the precision series or another higher grade as the photos show 0.2% 10ppm will not made in China.

I got 68Ohm of the 0.2% metal film resisters sample already & try to use in the I/V of the kit, it really very good. The black one is also precision but non-inductive. So the precision grade, non-inductive one & the 0.2% for I/V will use in the ver.II kit.

thx
