Make sure to clean all switches, that could solve your issue with the phono. Also the small relays might be the problem. Good job on the recap, did you also replace the double diodes on the phono boards and on the power supply? The last mod is sometimes questionable, but I replaced those, just like John. To get the desired -10.5v you would have to replace two resistors r73 and r74 from 5.6k to 3.9k to reduce the voltage drop over the trimmer circuit and so to increase your output voltage. Look at John's posts about this.
