I have two 1k resistors and 150uF Capacitor, i see on yours there are one 2k resistor and 470uF Capacitor, and an extra 470 pF.
By the Line in, you got 10uF and i have 0.22uF Polyester Film Capacitor .
Wonder if there maybe should be an 470 pF between the two 1k resistors?
You can see on the photo all the differences i discovered. Red markings seems to be the same as on yours, blue numbers are different
I would assume yours in correct for that version unless it looks like they have been changed TUAC were continually changing circuit designs all through production. I have a TD500 I will try to get some pics the next few days.
Were the 0r33 resistors ok. Out of curiosity have you checked all the output transistors ?
The diodes you have marked as 1n4148 next to .1k 250 either side of the op amp I'm sure should be 15v zenners ?
0.33, no.. they were about 4-6 ohms, all of them measured differently.
The top one BC182B i got and it has one shorted leg. I waiting for a replacement for that.
Same as the output transistor marked 14, Hfe should be at minimum 15.. Found an original with same labeling.
I just found out that the 10 ohms by the 40871 are Wirewound. I will replace all of these type of resistors with Wirewound Cement Filled Ceramic.
I thought before that these two where 1n4148 next to .1k 250 are now changed to 1N4109 on picture, check on the image at the top of the page
