Help with diode bridge and bias supply wiring
Posted: Fri Aug 04, 2017 7:26 am
Hi!
Just aquired a broken marshall jcm 800 4210. I ordered a ptp 2204 board from a guy named Walt from Ebay.
I have installed the board using this layout: http://imagizer.imageshack.us/a/img923/7464/csvXym.jpg
This is the layout for my ptp: http://imageshack.com/a/img924/2359/LcsqP6.jpg
Now... I discovered that my PT did not have an Center tap and that i have to go for a full bridge rectifier and change the bias circuit a bit.
Here is a picture of the actuall board: http://imageshack.com/a/img922/4094/8XNscd.jpg
Can somebody please give me a step by step on what to do?
Best regards
Kennet
