Naah, no good anymore, rather confusing on first look without had read, those come from different protos arrangements, lets revise up to what's adopted up to now and synchronize them schematics a bit.

Now we have all that is needed to build the Itch.

Thank you Salas and Fran.... Great work.

Default An Offer!

Way back as I was starting my build, a member here, vgeorge sent me a matched pair of 15nF silver mica caps. I think they actually measured 15.3nF - some might argue that the difference will affect the RIAA, but personally I think there's a hundred other things that will affect the tonal balance of the phonostage first.

I have since used some K42Y-9 instead. To be honest, they sounded a little more "liquid" than the mica, which were just a bit brighter. But on a different system and cartridge, they might be just the ticket.


Anyway, first person to send me a PM looking for them can have them free, posted regular post. Don't forget to include your postal address.

Salas, I'm putting together a bill of materials from mouser etc for the parts. Would you mind going back and numbering the components on your schematics above?

Thanks,

working on it, will have it in a day or so.... it'll need checking by someone and most likely correcting too. I'm assembling it from my past mouser orders, so I may have bought say, 1% resistors for something else, and only 10% are needed here. Or maybe I listed all the 5W resistors in ascending price order and picked the cheapest at that time.... anyway you get the idea.
