That is high temperature hot glue, as used in crafts that require strong bonding. Just pop off the old stuff first.
What glue to use on circuit board of Classe amp
I have a Classe DR-15 amplifer on which a couple of electrical parts that were glued onto the top of one the circuit boards have come loose. It's a clear colored glue that has come loose. What type of glue (or brand) should I use to re-glue these parts to the circuit board. Thanks.
