Congrats. It is amazing to know ppl are so rich they can buy these gear brand new & just abandon them. They are worth a good chnage in my country

nice video👍🏼do you know how this compares to my Yamaha m2 amp 2X 244 8ohm❓I have both Yamaha m2 and a dynaco st70 valve...both sound very good!...wondering if there is a better amp to pair with my Tannoy Berkeley speakers❓

Very interesting video and it is always a pleasure to hear The Jazz Kings (Australia) through a quality sound system. Thanks so much.

From memory the Stereo 20 was slightly simplified. T&D were said to be very unhappy at being copied. As someone pointed out , if so why publish in a magazine ? It was very typical to use published designs. Mullard and RCA. Dynaco being RCA. RCA happy to sell the parts. T&D was based on the H C Lin circuit of 1957 . Peter Baxendale made a big improvement which Naim used.

Is there any way I could make my own organ stops? I only have a non-organ 61 keys keyboard

Nice job Stephen. Enjoyed this video.

These are a crib of LS3/5. Had nothing in common with the BBC design.

Nice video. You might want to replace that gold Elna cap. Ive serviced quite a few 460s.and they're always bad. I think the CD has a similar cap as well.

Again, correct me if I'm wrong but is that a halogen bulb on the dim bulb tester? That is less likely to burn out than a standard incandescent bulb, thus lowering its function as a protection feature.

Beautiful circuit on these amplifiers. I admire the design. Reminds me of well engineered amps like Dynaco or McIntosh.

I think a potential mistake you made here is not reforming the filter caps for a few hours, please correct me if you did. But as long as the amp is working for a few moments in test, put the system on a dim bulb tester with say a 100 watt bulb and let it ride for half a day. Testing the ESR on a cap like these without at least running them for a few hours, on equipment that likely hasn't been worked for months or years or decades, give them a chance. I have replaced so many filter caps on principle only to later realize that just running them for a few hours and they test as well or better than the replacements at high voltage.

This particular amp is a low end amp. It’s cheaper to buy another one. There dirt cheap on eBay.

Would you possibly share the name of the Japanese dealer you mentioned? I do buy items on yahoo Japan and once in great while from Hifdo. Thanks

lol you should try some chifi clones like the fm300a, they are awesome

With vintage receivers, unless I see pre-outs on the back it aint worth it to me either. That being said, I'd LOVE to have an all matching vintage Yammie rig! Nice preamp/power amp combo with sufficient juice for a pair of NS1000's, id be in hog heaven : D

I worked at a HiFi shop in Austin, TX when this receiver and CD carousel were introduced and current. Killer combo that we sold a ton of, especially with some nice higher efficiency speakers (like Klipsch or Boston Acoustic). GREAT FIND and not at all surprised this receiver is still alive and kicking.

One of my 3 Yammy amps is it's slightly bigger brother the AX-550, great amp that's waiting for me to give it a full service, the input selector is hit and miss on all the inputs. The remote of my 2001 AX-596 works on the 550 no problem.

Nice...perfectly logical approach also

Very nice amplifier. What source were you using?

Is the LED indicator supposed to turn on immediately when the unit has power?

Friend of mine had one of them in the early 80s, great sound even when he used to crank it right up. Would be interesting to see how those filter caps measure up after a bit of time.

Beautiful laid out amp!

No, we don't know who the other reviewer is. Actually there is only one other Accuphase C-202 review on UA-cam (13min 56sec) and it doesn't say that it colorizes the sound.

Next year will come to bitung north sulawesi indonesia

Beautiful piece of technnology...

Noticed an audible difference sharp spikes bring about. Have a felt backed, soundproofing carpet resting on additional cork sheet on a concrete floor at mine. Low frequency definition improves markedly with spikes allowed to dig into the concrete vs. just resting on circular, locating pads they came with. Not sure how to describe it, but when anchored, the lows seem deeper and hit harder, in a more point like fashion. Wonder if it would work at yours. Obviously, the spikes are shaped like a tip of a dart, rather than a cone and about an inch in length, so that the speakers are elevated above the carpet. Once levelled, a nut allows to lock the thread in place.

Beautiful amps! I have ordered lots of things from Yahoo aleado through Jauce. But I never ordered expensive stuffs. Only cheap vintage Japanese turntables, accessories. Packaging was always bombproof. At my very last order the guys in Jauce warehouse broke a stylus of cartridge and never admitted their responsibility and fault, so I have stopped using them. Also DHL raised shipping prices crazy high in the last three years, so only rare and expensive hi-fi gears worth to buy from there. And yeah, the risk is always there... impossible to repair because someone already messed up inside. All my gears working now I bought from Japan, but required lots of hours refurbishing. Greetings from Hungary Sir! Enjoy your spectacular system!

Very nice ! Congratulations 🎉

Great build quality and sounds good even through my computer speakers. Interior components and layout looks very similar to my Luxman L-100 integrated and M2000 amps.

Please read up before posting, as these faults are all classical. The R7/8 that caused this fault, must be replaced by at least 1W 3k3 or it will blow again. The classical faults are different related to PCB rev.

Which site or home page did you buy it. You didn't say it😮😮😮😮😮😮

Twin transformes... Mmmmm.... Thants very nice, great gear..!!! You din't mention how much it cost. Please don't forget to meka a video of the changing off voltage from 100v to 120v. (that would be amazing) Thank you.

Congratulations! What a great pairing and what a wait you've had. Wishing you hours of listening pleasure!

Very nice, enjoy it!

Hey man thanks for all theses informations, I have a few questions though, ( I don't think I got everything right english is not my mother tongue). Also I know nothing about this hobby, just getting started. But basically I am currently playing music from my computer sending qobuz tracks to my audio gd R28 NOS going to my Arya stealth headphones, I am looking for a clean source, would that solution will work for a headphone set up? Also I am not sure i get how you connect all this, could my laptop send the information to the raspberry related by I2S to my dac/amp? Does that make sense? I wish you a good day, thanks again, bye!

I also have some amplifiers to repair that I can help with

If the clearance is there, soldering to a cr123 is very easy! Maybe top mount is possible?

You could have put the star washers in vinegar, it would have restored then sufficiently for this restoration.

"Not too bad"??? I own several receivers made in 1973 that looks brand new!

OOOOO-m-g!!!! These crown ce-1000/ce-2000 amps are some of THEE WORST amps to work on. I've seen a service manual and it's at LEAST an inch thick!!!! Pretty sure crown outsourced the design to china or japan. WAY to much smt in them! If you have a working model enjoy it while it lasts. If it breaks, sell it cheep to someone that can use it for parts and just buy a new amp, cuz none of them are worth even the most gifted techs time!!!!

I am trying to recover mine, all is now working, except for when the treble is 100%, it sounds like voltage interference going through, and one resistor next to big capacitors R721 gets really hot and starts smoking. But if I bring treble to 80% all is good.. any ideas? Thanks

Hey congrats on your recover..

I build an 7C clone, etched my own circuit board, using 6 tubes 12AX7 and used regulated voltage. Deleted the tone controls and volume pot. I should make a video soon, i focused on the RIAA circuit and calculated for best curves and used best components. It sounds amazing, I'll post soon. Nice video by the way!

My 80s PIONEER amp. @110-watts per side @ 8-ohms. hisses a bit after 10-oclock it always has.. It's not a loud hiss but you can hear it a bit.. I don't think there's anything wrong with the circuit... You do great work...

where you bought it? could you share the information?

Estoy buscando una SOLUCION a "instalar " un Radio Fm o receptor de frecuencias Fm (93.5 en mi país emisora deportiva y noticias) por internet a un Amplificador Fosi audio ZA3. Será que lo podré lograr con un Rasperry. ... y de paso será posible hacerle o existe un Control Remoto (como el de las TV) para controlar dicho Rasbperry, .. espero no estar pidiendo mucho, jeje

The blue cap looks like a tantalum bead type.

i thought they were sideways not vertical

Great vid just wondering if you have worked on the bbc modded version? I have one that keeps tripping the mains,any ideas?

Having brought an amp that was released around the same time as the 3020 (Denon PMA350) as a gift to myself for geting my first proper paid job, I'm starting to feel old now these are referred to as "vintage" 😅
