A comment on the coupling caps - some folks (including myself) have gone for more fancy caps like Auriocap, Clarity, Jantzen superior Z etc. As I have not done any head to head comparison will not be able to comment on the real life difference between your choice and such caps. Since you plan to order from PE, you can look up the Jantzen Superior Z and see if it fits your overall plan/budget:
Jantzen 0.22uF 1200V Z-Superior Capacitor
The EH 12AT7WC tube doesn't have good feedback on the PE site (albeit the application for the customer was not a hifi amp). Anywhere else you read reviews?
BTW, you will need 3 x 8 pin socket for 2 x EL34 and 1 x 5AR4.
1 x 9 pin tube socket for 12AT7. (Probably you already knew that )
Thank you for the suggestions. I have few fancy caps with me but not sure about the voltage rating. If it is below 600v I will get those Jantzen or this.
I didn't checked anywhere else for EH 12AT7WC as I have wholesale account with PE.
Any way i will be updating few items before placing the order. I will post the updated list soon. Planing to go for KT88 instead of EL34.
