Many capacitors ,resistors and transistors aren`t originals,but now I have one very big problem.I have the partlists from Geoff,but now I replace the parts and.....I can`t find any coincidence with the Geoff partlists.I don`t know....
If Geoff or any other one can help me with any other partlists will be great because I can`t restore this amplifier without this info.
My amp is on the pictures.Model : 3020A ,Made in Taiwan.
Thanks!

The LED wattage indicator is an LB1405 DIL IC on a wee daughterboard IIRC, possibly Sanyo.
LB1443N is a 5-led vumeter SIL chip in my catalogue that could possibly be used. Or if such things are rare in Bulgaria the LM3915/6 is an option.
My service manual (from a member here - pinkmouse?) is different to the one edl linked, copy (10Mb!) here.

May be this is my amp,but I can`t read the parts symbols with this quality;or may be not.
If any another one can help me with any service manual for the NewAudioDimensions 3020A will be very great ,because if I can`t find this schematics I can only dump this amp

Hi
I can`t find any usefull manual for my 3020A. May be anyone in the our forum can help me,because I am broken in spirit.
All old parts are in the dust-bin,the PCB is like new,but I can`t buy new parts ,like the resistors,capacitors,diods,because I don`t know his places on the PCB,and may be his names.
Pls guys,I write and read only in this forum and my hope springs eternal
