Postby IGGY » Sat Dec 22, 2012 8:05 pm

Can I use 1650R in the eiclone instead 1650N? Any stock part need to be change? I plan to use KT120 for new eiclone project.

Regards to all,
Iggy :/

Well you will need a lot more bias , Are you going to cathode bias or fix bias ,I would use the Edcor CXPP100-MS-4.2K http://www.edcorusa.com/p/458/cxpp100-ms-4_2k

I think that will work fine with a KT120, Iggy.

;) Thanks ! Shannon,

I received the Ike pcb...thanks again. You said.... you getting around 80 watts with heavily bias KT88 on the stock Ike. I like to try KT120 with 1650R (100 w. opt).
I'm concern about 1650R wring. Can I use the same stock (1650N) wring diagram ? Any parts valve need to be worry about?

Best Regards,
Iggy
