Marantz 2275 Repair & Service

Chris fixes a noisy old Marantz 2275

[@mr.mrs.witowski29]

After having a desoldering gun, I'd never be without one, even for one, large project, like re-capping an old receiver/integrated amp. I purchased a cheap Anesty unit and it's amazing! Components usually pop right out after one try with this unit and if you have the temp set right, it won't damage and lift the pad.

BTW, for those still learning, when he said, "that's a good sign", what he was referring to was the speaker protection relay kicked it. If you don't hear that distinct, "click", a few seconds after powering on, you still have Power Amp issues.

Wasting time. Change all power supply caps, burnish the relay contacts, change the several output board caps, change the preamp, tone board, flat amp, phono and fm board caps. The main filters are generally fine. Clean the controls, trims, align the tuner, lubricate the tuning string pulleys and tuning knob bearings. Change the fuse lamps in the scale and set dc offset, bias and power supply voltage.

Gracias por compartir!! Thanks dude!

Nice job

Nice info, thanks for sharing :)

Great Video, I have a 2275 and the right side speaker has considerable lower volume and seems to be missing some highs ?? What do you think the cause could be ? Thank You .. JoSoFo

Hi, I have a 2275 that needs lights and servicing. It plays music from the aux input on both channels. Where are you located?

[@Kyussrules]

I’m a newbie what do you set your multi meter to when checking your idle current? Thanks

[@chrisbrewer8036]

On a Marantz, set it to DC millivolts. You can also set it to DC volts if your meter can resolve 1/1000 of a volt on that setting (.***)

Great video, do you have any recommendations on what to use to clean the glue residue off the circuit boards or do you not worry about that. i'm thinking corrosion. Thank you!

[@newenglandhi-fi9835]

The glue Marantz used was/is pretty benign, and they didn’t use a lot of it, but we usually use IPA to clean it up.

[@toddm9957]

What does it cost to do all this i have a 2216b that has a channel out and would like to fix it or have it fixed?

[@mangist]

A channel out could be output transistors or other transistors on the boards. Maybe $200-300 to service.

[@andreveers2483]

Great job! What type of caps do you use on power board? Are audio grade okay or are another type better?

[@chrisbrewer8036]

Audio grade caps tend to have tighter capacitance specs, but higher ESR. It likely doesn't make much of a difference on a power supply board, though, so really just use whatever you have.

[@SurnaturalM]

Nichicon UPW-UPM are great for power supply.

[@sampahtetapsam21]

Is it better than 2270

[@newenglandhi-fi9835]

Yes, paying someone to do something you won’t or can’t do is generally how it works.
