Maintenance on Hafler DH200 & DH101


I just acquired these two units from a friend. Just wondering if there is anything I should do to maintain them. I plan on cleaning all the switches with deoxit. I was told by a local repairman that the caps shouldn't need replacing, but I'm not sure what he bases that on. Any suggestions based on experience? Also, can anyone comment on the sonic signature of these two pieces?

Thanks, Peter

The DH200 really didn't need any maintenance. The DH101 has two weak points. The volume comtrol can get noisy - use contact cleaner if the pot has an access hole (the noisy ones usually did). The switches would stick in the white (on) position - electronically OK but cosmetically annoying). Use a little super glue to glue the catch back in position.
