Nice! I have a DH500 and the RCA inputs are deteriorating on the inside. Occasionally I have to mess with the cables. I think as stage 1, I will give the insides a bit a of a clean and replace the RCA jacks. Which RCA jacks did you use for this one and did you have to open up the holes in the chassis at all? Thanks in advance. Grace and peace, Ben

Sorry, the RCA issue is on the Hafler 500 amplifier. I was responding to a couple things. All the photos are of the Carver. I believe my dad got the Carver new and never had it in the shop, so I am pretty confident it is all original. The problem with the Carver is it going into protection mode after a few seconds (except when it doesn't and works fine for a few months).

Thank you all for the warm welcomes and I apologize for the extended delay. The Carver began working again for a number of months. I opened up the Hafler DH-500 and could see one of the terminals (I do not remember if it was RCA in or Speaker out) had turned far enough for one of the posts to be touching another terminal or the case. It now has been working very well. Occasionally I will have to adjust the RCA in as a channel will cut out. Once I have some spare time, I will open it back up and see if I can tighten up the jacks or may need to replace them (any recommendations on replacement RCA terminals is welcomed). I was able to pick up a Hafler DH-110 preamp a couple of months back for a good price locally, so I have my Technics SL 1700 playing and picked up a second hand Apple Airport Express A1392 to use a decent streamer. I briefly opened up the Carver and will post a few photos. There are no signs of leaking caps but I do see one of the larger caps has some deformation on the top. I'm out of town for the holidays but will have to take look at the repair manual and get my multimeter out when I get home to check out Ryan's findings.

Thank you all for the quick responses. I hope to open it up this weekend.

Hi, My dad bought some Carver stuff back when I was about 10 years old and now I have some of it in my living room as a 43 year old. I am currently utilizing the HR772 and 90% of the time it is working great. Occasionally though, it will turn off a few seconds after powering up. I have it powering some Hafler Model 400 towers. I also have a Hafler DH 500 but it is giving me some trouble too. Dad used the HR772 to run some JBL L36s for a while, then the Hafler Model 400s. He borrowed a couple of my Kenwood L-07ms for a bit and then we found a DH 500 for him. When using the DH 500, he used the HR 772 as his preamp. This was my intention when I inherited them, but the DH 500 needs some work. In the meantime I have been using the HR772. Now it is giving me some trouble. I am mechanical engineer by trade and am comfortable with tools and can brush up a bit to read some electrical schematics, but make no claims to be an electronics expert. I have a Dim Bulb Tester that I built a while back, but haven't plugged it into the Carver yet. I have a soldering iron as well. I also am open to recommendations on shops if that seems like a better route. I live in Atlantic Beach FL (basically Jacksonville). Thanks in advance for any direction. Grace and peace, Ben
