New to this forum, I recently rebuilt my speakerlab delta I type 4s with help from Paul from the loudspeaker store. I bought these as a kit back in the mid 80's. I have a Denon PMA-700V from same era and thought I would give it a little attention. It sounds great with the above speakers at low volume but I realized the speakers needed new surrounds, and the 8 in drivers were shot, hence the rebuild. With Pauls help, I added a true Nestorovic circuit to the coupled 8 in / 10 in bass driver circuit. So with these speakers revitalized, I thought I should take a look at the PMA-700V. Two of the 8200uf 63V power supply caps appear to have stained the glue on the PCB. Since the amp was working fine I am hesitant to just blindly recap it.
