6 hour drive to visit my folks. So you know what I did? That's right. 6 more hours of live Grateful Dead. Tidal to FM transmitter deal via Bluetooth and then to truck radio. What an age we live in.

Completed 6 straight hours of live Grateful Dead from the Europe 1972 tour on Tidal and it still wasn't enough. Seriously good solos by Jerry in this version of Goin' down the road feelin' bad.

The service manual is in the database. it will list the values of those resistors; https://thecarversite.com/manuals/mandir/Carver HR-722 service manual.pdf

Welcome to the forum. My first thought would be a dirty input level potentiometer. You could try spraying the pot with some fader lube and rotating the input level knob several times. See if that gets rid of the static.

They must have had smoother roads back in the '50s.

Abe Vigoda?

Beautiful theater room.

I use a Moon LP3 that i bought about 15 years ago.

I pity the fool who answers his questions about the tfm15 incorrectly.

Welcome

Welcome to the site.

Welcome Sean. What Sunfire models to you have?

If you have cleaned the volume pot and it still crackles or you have channel drop out you probably need to clean the balance pot. I am no expert, but I use fader lube on pots and contact cleaner on switches. Both caig deoxit.

Perhaps you could list the equipment that you have and we could walk you through how to set it up.

Welcome. I need a buddy that gives me free amps. I only have a buddy that brings me stuff to fix.

Crackling can be caused by some transistor in the amp section. Q701/703 and Q702/704. (2sa1145 and 2Sc2705) I would start with replacing those.

I wonder if the C-1000 is really a true Carver product or if it was a modified unit based on an existing or partnered design. The reason I say this is because the front and back panel layout of the C-1000 are very similar to the Rotel RSX - 965 DD/DTS receiver (75 watts/channel) that came out around the same time. Google some pictures of that Rotel receiver and you will see what i mean.

The C-1000 has only composite and S-video so it is useless for video switching. (not all that important to me or many others). I owned a used C-1000 in 2004 and it spent 6 months in the repair shop. It was horribly problematic. The sound was nothing special. Granted it could have been a bad unit all around. It has pre-outs for all channels but you can't use it as a 5 channel amp on its own. They look great but frankly if something goes wrong with it I think it will be very difficult to get it repaired. There are simpler and better options. My 5 cents. (we don't have pennies anymore in this country so minimum is a nickel)

It's pretty difficult to repair an amplifier without any electronics knowledge. If it's blowing fuses there could be some major faults that you can't find just by looking at it. I'd say take it to a repair shop if you want it working.

Welcome. Sounds like a good system you have. Is your C-1 a stock unit? If so, there are several good upgrades to improve the sound quality.

Welcome to the forum.

My Sunfire Ultimate Receiver is quite sensitive to any DC on the main line. DC from appliances such as my humidifier. Even a few millivolts causes the Sunfire transformer to buzz.

I wonder if the new owner has DC on the mains?

Welcome. I would think Nelion Audio could also work on your Luxman amp. Ask him. What speakers do you have?

I reckon you best be gettin' a dog, Mark.
