What's the proper way to put this tailpiece cover back?

Hi,

This is my beloved Yamaha SA20 12 string. Since I plan on selling it soon, I'd like to do a proper job putting the cover back. I guess this is a common problem.

I hope I can pick from my glue collection at the shop. I've got : silicon glue (gel form and spray), regular epoxy, super glue, and, of course, some tubes that I don't remember the name because I used it once long ago.

Thanks for your advice!

Eyelet/rivet + tools for PCB via repair : what to buy

This poor relay died and took the via and pad with it.

I've been googling for the proper way to repair vias with rivets. I've found many rivet kits for M0.9 to M1.7 OD size, but this one needs 1.8mm ID, for about 2mm OD (I can reshape the hole if needed). These are harder to find, so I thought why not ask for a little help.

Also I have not been able to find the right tools - meaning affordable - for the job. I may lack the right keywords, so help would be appreciated her too.

Note : I am aware of other techniques for repairs like this. My question is about rivets or eyelets only.

Traynor YCV40 slowly rising power

Hi!

I have this Traynor YCV40 on the bench. The problem is that the high voltage is not reaching adequate voltage. Also voltage A-B or C don't change when switching the standby. Being not familiar with this power supply topology and all the switching, I'd like some help to understand better what is going on and have a better idea on what to troubleshoot first. Also, since it is a time consuming type of amp to work on, I'd like to get to the point without having to connect and disconnect over and over.

I get like 275V at voltage A with no tubes, and around 67V with tubes. I did try with known good tubes also, so I know it is not the tubes. I guess the voltage drop is just because there is just not significant amount of current in the circuit. Otherwise, I get about 440V on the right side of D7/D8.
