So i got a Super lead MKII '74 on bench right now with quite a bit of ghosting going on. According the person who owns it, the ghostnotes was just there all of a sudden. After only visual inspecting i saw that the filter caps was bulging it, so time for recap and some maintenance. But once done the ghosting was still present. What has been done so far is: 1. Filter caps replaced 2. Screen resistors replaced 3. almost every dropping resistor in the B+ since they were way way off. 4. Balance resistors on the screen filter caps. Upped them to 220k. 5. Checked all ground connections. 6. Brand new tubes all the way, checked with other know to be good tubes aswell. 7. checked coupling caps. 8. checked diodes. 9. Measured choke, seems fine at 110ohm. I even tried with a Resistor in its place just be sure. 10. Measured OT. 11. Checked all the voltages, everything is within "spec". 12. Tried with upping the main filtering to 200uf. I tried to scope where the ghost notes originates from and i cant quite pin it down. I know that with every tube except v1 pulled it is still present after the bright cap, even with the cable from the wiper pulled. So i tried to provoke on the normal channel with a bright cap on the volume and it was there as well. I'll attach a picture of what the sine wave looks like on the wiper with volume set to 2-3. I presume that that harmonic is my little ghost showing. So some hints on what to look for next would be very much appreciated. any ideas?
