I was so excited this morning to re-assemble my MP-1 after completing my re-cap and component upgrades...only to fire it up and feel the pang of disappointment.
Whereas prior to my work, my dist/clean tube channels were reversed, now when I fire it up, nothing happens other than a few lights on the main display.
Based on what I've read I'm thinking it could be any of the following:
1) I screwed up a solder joint on one of the many caps I replaced or another component.
2) I damaged a diode. In particular, there was a diode I mistakenly de-soldered (and likely damaged from heat) and had to put back in. It's the one with the white arrow in the pic below. I'm going to get a new one and see if that fixes the problem.
3) The 2SK364 transistor I replaced was/is faulty *or* the 10uF cap beside it is faulty and fried the new one I put in. Serves me right, wasn't thinking when I put it back together I needed to wait to get a new cap.
Any other ideas? I really can't stand the thought of using this for spare parts after spending $100 on upgraded components, there has to be a logical way to troubleshoot this - any suggestions would be greatly appreciated.
thanks!
