Only the midrange that is closed to the original and the other area I tried to improve. I'll see.

I have the unit here and it is a clone Marantz 7 and extremely well built, and it come with tube regulation with 6J1 and 6V6.

What I'm going to do is adding 2 x Salas SSHV2 after the tube regulation for circuit, and my friend order for me, and now on the waiting list. I retain all small caps except the output I will use 0.47uf.

Those 0.01uf I will try the Super Mica that mentioned in the positive feedback articles.

I have some Sprague orange drop PS series 0.22uf that I bought to refurbish my vintage collections (Pilot, Heathkit, Fisher and few others) 2 decades ago.

22AWG Jupiter cloth tinned wire will be used for signal.

I don't know what would it sound like, and I might try to do some treat and see.

Thanks for you guys helps!!

PS. I try to keep all values small instead using large cap.
