Hi
Thanks for the info regarding green components
Chasing the green color:I have tested the following neckboard components in circut
D311 - OK
D312 - OK
D313 - OK
D314 - OK
R316 (100 ohm) OK
R311 (120 ohm) OK
R312 (33 ohm) OK
R314 (18 ohm) OK
R315 (5.5 ohm) OK
R310 reads 0.466k ohm also when pulled out - I can read the colors but i THINK it is (yellow-blue-red-gold) 4.6k ohm
R317 reads 280 ohm also when pulled out - i think that the color is (red - violet - brown - gold) 280 ohm
So I have tested all the 31X parts, and still not found the faulty component

I have NOT tested the Q1X's but I am unable to read the part number's - so if any can tell me what they are it would be super

My best guess to the Q1X parts are 2SC4218 and 2SC1624
Must the transistors be exactly the same, or is it OK to replace them with some with the same values?

Chasing the 25V at vertical IC:Only 22.8V at pin8 to low.... so I have pulled out and tested the last caps that i not have changed in the PSU section
C955 (180uf 25V) Reads: 186uf ESR 0.54 ohm vloss 1.3%
C951 (180uf 100V)Reads: 183uf ESR 0.00 ohm vloss 1.0%
Can it be low due to my last two caps?
Need the experts advice...
