It's nice to see that someone else has the same tribulations with restoration. I'm far from a pro, but I love troubleshooting, repairing, and restoring vintage audio. Sometimes, my attempts don't quite meet my standards, but I continue to get better.
Bro... Respect. I'm finishing my Marantz 2245 and it's been a heap of work. I have the right amplifier board, AM and MPX Stereo boards left. Then vellum paper, bulbs and tuner string. I'm in love with how this receiver sounds. It's beyond what I imagined compared to my Yamaha AS501. Smokes that thing so bad.
Long time viewer., glad to see you putting out another vid. Your work on the bezel reminds me of things I need to do when working on motorcycle parts. As a tip, I would have made a blank faceplate out of aluminum to hold the bezel together outside of the faceplate, Then I would have used some epoxy or bondo to fill the joint. After curing, I would have then sanded and polished the bezel, followed by painting. Then remove the blank and install the glass plate. I'm not being critical, just trying to solve the issue together. Keep up the good work!
I am considering the purchase of a vintaged 1980 model year Realistic AM/FM Stereo Receiver that has been cleaned as all functions work! Is it standard procedure or is it recommended to replace the electrolytic capacitors in the unit? What other electronics might I want to inspect inside the unit? I enjoyed your video on that tedious Marantz 2230 tuning wheel & pointer repair!
The work you did on both receivers was outstanding, Especially the Marantz. The 3D printing of the bezel was not perfect but it was still pretty damn good!! If that were my receiver I would be ecstatic! I appreciate your dedication to restoring vintage receivers. Your videos are so interesting considering I know absolutely nothing about electronics. Keep up the the great work!
I wondered what happened to those 2 pieces. Nice to get things off of our to- do list Aidan. Nice demonstration of how multi- tasking can be challenging in focusing on the task we are completing
AH - Does the SX-737 have a great FM tuner? I'm thinking of buying one but I need really good FM reception. Also the 737 was produced over 3 1/2 years and my local tech told me he thinks the later (1975-1976) model had some changes to the tuner that gave it better performance than the earlier model. What do you think ?
I agree with you about the electrolytics. Nowadays everyone seems to replace them with film capacitors. Not a good idea unless you use polypropylene caps but these are way too big. Many people cannot hear the difference, but the better your source, speakers etc, the more obvious the difference becomes. I use an old Fluke 45 for power measurement, so I don't have to do the calculation and you can do 20 Khz 😀
All of your restoration videos have been brilliant. I can vouch for the quality of the Vintage Hi Fi Audio products. After watching your video I bought a face plate from them and with new LEDs and vellum paper my Marantz 2220b almost looks like a museum piece. All I need is a selector knob, and they are currently back ordered.
Good to see you Aidan and glad you were able to resurrect these two zombie receivers back into the living. Landfill destined vintage equipment that is saved to enjoy is a marvelous thing and a great job you did to be honest. Had my doubts in the very beginning😊 Alignment video will be a nice subject and interesting seeing the results. Montana in the summer time, trout fishing must be fantastic. Thanks for the work, see you next time.
Hello, in watching this video I see that you have a 3D printer. By any chance, would you be able to 3D print the AM swing arm and bracket for a 2252B receiver? I'm in the market for these two items and cannot find the parts anywhere. Thanks.
Nice video and thanks for the entertainment. Your speaker knob doesn't look to bad, I would try some solvents to see if the black will come off. Start with industrial goo gone and move up the ladder of stronger solvents like MEK on a rag. If its still there try some 320 or finer sandpaper and sand in a circular motion. Lol one way or another it will come off.
Awesome, I been watching the series. We know is not your day job. I have a sx 750 that I got for almost nothing. Already got going, I did wash not exactly because of you. I done before using a modified tektronix protocol. The wood case on my is beyond repair, I will do a hardwood case. Hunting Dow the speaker and plug plate, mine is just to rusty. Anyway great video, restorations and weird repairs are just like. I was pretty bitter last night, with my Sony 1120 😂😂😂
You mentioned electrolytic capacitors and the possibility of the loss of the Marantz sound when film caps were used as a replacement has me thinking maybe my repair tech may have replaced the electrolytics with Film caps in in my Sherwood HP2000 integrated amp because it doesn’t have that warm and detailed sound it once had. A noticeable Loss of highs for sure
I replaced all the electrolytics in my 2250B tone board except the bipolars at the output of the stage, since I didn't have them. Came back to it later, replaced the bipolars with film, and the improvement was dramatic. I measured the ESR of the original bipolars versus the film - the film was less than 1/10th the ESR.
You should have 3D printed the pieces with offset seams. Less noticeable. Go 1-2" to the right on the top and the same for the bottom left. You might also 45 degree them and overlap for a cleaner fit even. Some light sanding would probably still be required. But then again, that's a bunch of work. What you have done looks great.
I think the Marantz looks pretty good considering how it was before. maybe you can try to fill the crack in with something Black Silicone or maybe JB weld & paint it black.
I would try some "Goof-Off" on the knob. Be careful with it though as it is NOT the same as "Goo-Gone" which is much less potent. If lacquer thinner doesn't remove it, the next step up is Goof-Off.
Good job. The average Joe doesn't have a scooby about what goes into a proper restoration of these vintage items, probably due to Ebay being flooded with 'serviced' items.
FM alignment is a standard maintenance function to make sure the receiver is getting the full broadcast range from lock-to-lock of the tuning capacitor. It typically involves moving slug (or two) inside an inductor. Each tuner has a procedure detailed in the service manual. After the alignment, the dial indicator may need adjustment. Basically, it is something a professional should do upon repairing a receiver before turning it over to the customer, at least that is my understanding.

Absolutely fantastic job bringing these vintage receivers bask to life!
Stirling work always a pleasure to watch.

Awesome! I’m glad you finally got them finished. Now if I could only find one that doesn’t cost an arm and a leg that would be great 👍

Thank you for giving these amazing pieces of history a long healthy life 👍🏻🤘🏻
Thanks! Do you sell any of your rehabs?

You said you were concerned about the 3D printed piece. You can use certain solvents like acetone to smooth it out.

Great video and excellent work 👏I would love to see fm alignment video for this receiver because I have to do mine at some point 🙂

You did a great job on the Marantz face plate, Aiden!

I use Mothers as well on faceplates. It does a great job and I have not had it do any damage to the silk screening.
Was looking to see you glue on some nice wood veneer 😊
Turned out very well and vintage hifi lives on.
Good job. The average Joe doesn't have a scooby about what goes into a proper restoration of these vintage items, probably due to Ebay being flooded with 'serviced' items.
How to contact u for service vintage stuff
They look fantastic, more important they sound good and will be reliable...ENJOY.....
Would've love to hear the Marantz also. 😊
Surely the system was designed with electrolytic caps, so film caps are only an inferior replacement!
nice work my man
Nice work.
Would you look at my McIntosh MC2500 power amp? It's a monster weight wise, where are you?
Looks great...
Nice haircut!
I noticed that too! lol
what is a FM alighnmet? is that code
You will see next video!

TERRIFIC video! sub'd/lkd. question: what's to be done with a garage-full of Peavey Pro Monitors?? And Bose 901s?
How are the kitty's.....doing......by the way 🤔
Why were they the "Worst"??. Seem fairly decent to me...

“More advanced users”. Lol! Never sell any of your watchers short. And, you seem awfully defensive about your work here. Chill! It looks awesome!
You can slice the heat sink down one side, wrap it around the string then heat it. It should still work like normal.
