Hello all,
The amp in my son's car stopped working a while back. We checked the fuses and confirmed that it is getting power. He was going to replace it but we found that you could order a replacement board from Rockville, so that's what we did. We have the amp opened up and the old board removed but before we just slap in the new board I have a question. On each of the long sides of the board there are some tabs that were held down with metal straps to the amp housing. The tabs themselves were not screwed down but they did have a white paste under them. I don't know what these tabs are or what the white paste is but I would like to clean it up and put fresh "paste" down first. It's this some type of heat sync paste or dielectric grease? Any help would be appreciated. I imaging Rockville isn't the only company with this type of design.
Thanks in advance!
Matt

The "tabs" are the power transistors. They MUST make GOOD thermal contact on the heatsink/housing or they will burn-up (again?).some tabs that were held down with metal straps to the amp housing. The tabs themselves were not screwed down but they did have a white paste
Best hit the "(!)Report" button under your post and ask to be Moved to the Car Audio section where members experienced with modern car-amps can advise on cleaning re-greasing and torquing.
PRR,
Thank you for the information. I asked for this to be moved to the Car Audio section as you suggested.

The white paste is heatsink compound. Dow Corning 340 is a good choice. You can buy it in small quantities on ebay.
How much did they charge for the board?
