How to solder the power switch without melting it ! :wink_face:
Don't worry about inserting tubes, they wont break in your hands. Just make sure you have the pins lined up correctly and it will take a firm push.
As for replacement switch parts - parts express, digi key, etc will carry similar switches.
Voltage check passed, plugged it in, it works! The first thing I notice is that vocals are IMMENSELY clear over the magni 2U. WOW. Actually, just about everything is tighter and clearer.
I look forward to installing the speedball later on and seeing how the sound changes.
Thank you everyone for your help and advice!
Edit
The instructions mention this:
"REVISION 5/6/10: Making this wire 3” long and connecting it to Terminal 14U instead of terminal 22L may yield more quiet operation" when connecting power transformer terminal 4 to terminal 22L. Has anyone actually tried both configurations and/or recommend one or the other?
Every couple minutes or so it will make a small noise in the right channel. It is like 2-4 different tones for a second or less one after another. It sounds around 2000-5000hz. Some static will accompany it. It's very quiet, and seems to get better when it's in use for longer, but it's still a little worrying if i'm going to put the speedball into it.
I noticed that the voltage checks were within range, but always on the lower end of the range. Is that anything unusual?
Edit: I think it's related to interference from my phone, wifi, computer, etc. Putting my phone right next to it makes the noise. I'm going to try and and cover the crack with foil and see if it goes away.
