Adding a 4th preamp tube to a 2203 Metro amp

Hello all,

I am wanting to add a fourth preamp tube to my metro 2203 Clone. It already has a spot for teh tube, just want to know a simple way to wire it up. Here is a link to my board/chassis layout http://metroamp.com/wiki/index.php/Imag ... IAGRAM.jpg

I have seen layouts on the metro forum, but they are mostly for a 1959 converted to a 2203. With the 4 inputs and slightly different wiring, they are a little tough for me to figure out how I should connect everything :oops:
If anyone could take a look and possibly draw me up a quick layout based of this layout, It would be much appreciated! :D

Thanks

Herbvis, I Would Like To Be Of Assistance, However, Just Saying That You Wish To Add A 4th Preamp Tube, Is Inexplicet, To Me. Would You Please Tell Me What Your Goal Is, Or Why You Wish To Do This? Is It For More Gain, An Additional Input, PI Boost, Or Cut? Some Direction Would Be Most Helpful With This Request. Let Me Know, If You Still Desier Assistence. 'Till Later Then. Bye For Now. Be Well, And Enjoy In All You Do! Tube-A Holic
