Fantastic work! Can’t wait to see the finished product of this one. Loving the videos and your attention to detail!

thank you for this helpful video!

Ihave a 2245 I got it a few days ago for 65 dollars

This is a neat and comprehensive work. I really like your idea of using socket to install transistors and how you raised the resistors, I will use this approach in my next projects. I was studying the SM to better understand this amplifier, it seems to have been engineered based on discrete components, which I like very much because of the warm sound it produces. Also, I understand that C006 and C007 are there to block DC to the speakers, but have you considered adding a reversible project to install a startup protection relay for extra protection?

Beautiful work! I’m gonna keep your philosophy in mind when I start my next unit: I’m just gonna do my best! That’s all I can do, really.

I an a retired electronics pro that worked for +50 years slinging solder and parts. Now I restore antique radios to keep out of trouble. When it comes to soldering people tend to use way too much solder and never enough resin. My favorite solder for general electronics is Kester 44 dia .032. The alloy needs to be Sn63 which is eutectic. I have found that the brass wool is way better that the wet sponge I used for many decades. A great replacement is my wife's Chore Boy. Be sure you have a supply of RA Flux that will easily wash off. I have used both IPA (not beer) and Brake Kleen to wash down boards after repairs. If you repair anything that will be exposed to harsh environments give it a quick coat of conformal coating or a quick blast of Krylon clear coat over anything you soldered. Sometimes adding some "fresh" sn63 to a joint makes it way easier to suck up the 'old' solder. It lowers the melt temp and is less likely to damage an old board. Get a small muffin or table top fan to clear the air. If you do a lot of soldering get a desktop smoke extractor. As to Thanksgiving foods? Spiced Apple rings are my favorite treat. Musselman's used to make them so now they have to be homemade.

Nice technique, clean tip with the proper amount of solder. and heat transfer to the joint.

Thank you! You are very inspiring...... am restoring one of the last 2270's

Good video. I’m swapping my 2270 to a black faceplate & black lacquer wood cabinet next week. I call it the “Darth Vader” edition. 😂

My new favorite channel. You are super inspiring and funny. I do this kind of work also, as well as speaker design, crossover design and upgrades and veneering. Let me know if you ever want to collaborate on a project!

Man I was having a rough day and you really cheered me. Thank you. I like pumpkin pie…with whipped cream!

Good job on the soldering - looks like factory done!

I love old Marantz gear. I have an old SR4400 6.1 surround. I run my Rega P1 through it. Sounds really good.

Six years as an electronics tech in the Navy and 40 years repairing office machines and I did a lot of soldering.and you're doing it better than me! I'm 67 and we just bought a new much bigger house. Now every family get together is at my house. I didn't think this through!

LOL at the inhalation, and maybe some safety glasses as well. Thanks for the video.

I bought a 1060 when i was 16, and donated it when i was 60 still working. It's one hell of an amp.. good to see people think its worth all the work to save and use.. thanks

Hello New subscriber good video informative ✌️

Your videos are outstanding in showing details clearly as well as taking time to explain the process. Thank you!

Sei appassionato del marchio Marantz

Brilliant video, keep up the good work 👍

It might be time for a fume extractor, we don't want you croaking on us.

That was a good and neat job! I hear you that sometimes we foresee that the project will be quick but it takes a long time. You were very patient. My soldering and desoldering skills were absolutely horrible (and I still have to do a better job), so years ago I took same training on YT from EEVblog and xraytonyb because I was just damaging the PCB and taking forever to desolder components. Look forward to seeing your next project. I wish you Happy Thanksgiving too. (PS- I also like to eat good food, but I can’t cook anything… so when my wife doesn’t cook, I usually have to buy food at Whole Foods, Trader Joe’s, etc.)

Been waiting (impatiently) to view part four this is so helpful. Who ever suggested using flux, what a great tip! Thank you! Thanksgiving is my favorite holiday. I smoke a Turkey. My favorite is cornbread sausage dressing that I prepare a day ahead so my wife can have the kitchen Thanksgiving Day.

Nice work. For my Rotel receiver, I bought small warm white led strips from AliExpress for next to nothing. I added a strip of tracing paper -almost the same as the vellum but I already had it in. Works well. Btw, I love the wooden prop on your wall. Something I've always wanted.

Great video man!!!! I’m thinking about doing a restoration project this winter. Thank you!!!

Fantastic instructions - thank you!

Why would anyone want a mono just left or right?

NOS for sound. Yea, I'm subscribing. Seriously, I came to view the lamp and vellum video and couldn't stop watching.

I have a similar preamp from the same era, are the transistors Germainum?

🙏🏼🙏🏼🙏🏼 no words to say.

The ceramic capacitor is probably just for high frequency decoupling.

I see them at goodwill an karm stores all the time.real cheap.20 an 25 dollars.im going to get me one.and try recapping or whatever it needs.you are very good at what you know.

Good job man keep it up

Hey man you are doing a fantastic job I wished I knew as much as you did just testing working on these little radios every now and then

This is a good and impeccable job! WIMA caps are a good choice for replacing small electrolytics. This amp must sound amazing playing vinyl too.

What model of transistor did you replace and with what? What was the modification with the wima's next to the filter caps. If possible please point out on the schematic what you are doing. I know it's a pain but it's the difference between show and tell and education.

I'm really enjoying this series. My Marantz 2220b sounds great but you're making me want to replace the filter caps and other caps that a man on eBay is selling. He has 100% positive feedback and thousands of sales. I'm retired and I have the time. Why not?

I think working with solder wick won't be effective, just use solder suck pump instead.

I’m scared to try it but want to so bad, I like you want to prove it to myself. I just subscribed to your channel, great job man you’re a great inspiration

Anything precautions I need to take before doing this?

you can also cut the braid so the heat isn't being wicked up to the roll. The smaller pieces heat up much faster and soak super easy.

Are you gonna sell the 1060 ?

Thanks for the tour. I have 2 of these in original condition and I've lifted the cover to clear the dust and always wondered what all that stuff is. May I ask what is a suitable lube for the switches as a couple of mine are a little sticky. Looking forward to your next video on this one.

One of my first pieces of gear when I was 15 wish I would have kept it

Still have mine. A few years ago I replaced a few caps, this has me thinking maybe I should dig back in there... Suggestion - a list of parts removed, and a list of replacements for each video? Thxs.

Great job buddy. I admire your dedication and persistence.

Thank you for sharing ......just left me with a question what type of transistor to replace the original one on the ower board ?

That's a good video and a good job. You did a thorough analysis between what was installed in the factory and what the Service Manual states, I found similar discrepancies when restoring some JVC vintage audio equipment also. I guess there might have been updates in the Service Manual while the equipment was still in production.
