as usual: amazing job with passion

Quick question. They indicate the output level of control at maximum. Does the input gain level set at maximum too? They don't say

Hi, I want to replace and upgrade everything on my Sony ta-f435r. It doesn't work anymore. Where can I order the parts?

Where did you get that Service manual. It looks nice and clean. Everything I have downloaded is dark and foggy.

Saw one at a local thrift store today, dirty and with user marks for €15,00 Hesitated because of its state and lack of the right tools (long screw drivers) for restoring it.What type of screw driver did you need? Maybe if it's still there I'll pick it up.

Best Regards from Sofia, Bulgaria. I have the same.

Hello (I am from Iraq). A wonderful and useful video. The most beautiful of all is your humility and your responses to all questions. I wish you peace and success.

Este equipo tiene el STK 465 gran integrado, Tengo un Sanyo DCA303 y lo hago trabajar con bocinas de 350 watt, de 15 pulg vaya mejor que una potencia y con sonido nítido, será que puedo hacerlo trabajar este amplificador con esas bocinas, claro le he puesto 4 ventiladores de computadoras para que enfrié el integrado, de esta forma lo he echo trabajar mas de 12 horas y como si nada. inclusive alguna vez le conectamos guitarras eléctricas, órgano, micrófonos de una banda atravez de un mezclador y nunca se daño. Sanyo hizo un gran trabajo con ese equipo, estoy buscando uno del mismo donde me encuentro pero no encuentro.

These amps can get HOT!

Can you tell me which test band with which reference band flow (nWb/m) you use for the GX 636 to achieve the 0.775 V (0dB) at the output?

Why don't You adjust the bias setting?

Many thanks for creating this video, super helpful! Going to do this soon as well on my c320bee. What caps did you use for the main filters at the power supply? (The big black ones rating at 15,000uf)

Thank you so much i have 2 reel to reel deck from 80's Akai rx625 and rx646 both have same problem they are slow and stops during rewind and fast forwarding and they both have same dual motor run capacitors and i don't know which capacitors to use as replacement I can’t use this deck for years any help deeply appreciated thank you in advance.

On mine, it looks like NAD raised the zeners and resistors high off the pc board. No overheating was observed.

Excellent thank you

The main problem is usually engines and mechanisms, not electronics).

the sound of this amp are good? not alots on review on the web

Hi Alexis Thanks for all your help

I like your style. You do good work

hallow my akai ther are no sound (out ) on rigt kanal ?

Hello. Please tell me, today do you still consider the NAD 302 a good amplifier or should you look towards the 352, 356? I have a Dynaudio Emit M20 and they need an amplifier with some punch and many people say that NAD is suitable for inexpensive ones. There is no money for KRELL or HEGEL(((. Thank you

What device would you recommend using with this amplifier. I'm looking for something that has a USB port that reads flac. Ila novice, please help. Love the Nad, I have had it for 30yrs

I own two of these amplifiers, a C316BEE and a C356BEE. I had the same heating problem with the C356BEE, I replaced both the zener diodes with 5W zeners, and the resistors (3.3 ohm/2W and the 51 ohm/5W). Regarding the cooling solution I simply bought the "AC Infinity AIRCOM S7" and placed it on top of the unit; it is a more elegant solution to this problem.

Which desoldering (make and model) are you using please ?

Ihave two of 590s, with two different main pcb... one is similar like this but the other is a basically different version... i dont know what happened, older or why ...

Thank you very much for these wonderful videos. They are very helpful. I would like to replace all electrolytic capacitors on my 770ES. Just like yours in the video. Would it be possible to get a list from you so I know exactly which ones I need? Best regards from Germany

Nice job Alexis. Finaly somebody has done an electrical adjustment on a Sony ES deck. I’ve done mine (TC-K750ES). A few points I want to highlight: Is your multimeter capable of reading the right AC voltages at 19kHz? (MPX-Filter check). As far as I know the UNI-T meter goes up to 10kHz when measure AC voltage. A multimeter drops down the reading at higher frequencies. Maybe an oscilloscope would help if you have one. For the Erase Current Adjustment you need to adjust RV553 at 110mV at 160kHz. I know for sure my Fluke MM can’t handle that frequency when measure AC voltage. Therefore I use an oscilloscope (no software scope). Probably you can’t read a voltage on your meter because of the higher frequency 😉 Do you use the resistors as mentioned in the service manual or do you connect your cassette deck directly to a function generator and/or meters? My regards.

ABSOLUTAMENTE FANTASTICO.

Good audio machine.

Hi Alexis, first of all I'd like to thank you very much for the great video and the terribly useful list of capacitors. May I also ask you if you do still have track of the varaible resistors that you did change (their value and type/size)? Should you still have a link at the Mouser/Digikey/whatever components, that would also be great. 😄😄

i think it had a service beacause c458 and c945 are original transistors i see that 2sc1845 wich is better than c945

Καλησπερα και συγχαρητηρια για τα βιντεο, απ τα καλυτερα στο ειδος τους. Εχω κ εγω 1 NAD 3020e, πριν και μετα απο recapp σε ηλεκτρονικο, συνεχίζει να εχει στο startup κ για 1 ,2 δευτερολεπτα 1V DC στην εξοδο του αριστερου καναλιου κ μετα πεφτει σε λογικα επιπεδα (10 20 mV ). Επειδή ο ηλεκτρονικός ¨σήκωσε" τα χέρια είπα να κανω εδω μια ερωτηση μπας και παρω καποια ιδεά που να ψαξω μετά.. ευχαριστω

Hi Alexis, fantastic restoration, it's Manoj from India, i have the Same GX4000DB, I need a capstan Sleeve and a Belt if you can help me to get it. Thanks

placed an offer for a 304 on e-bay, after reading a very positive review. i already have a more modern c 326BEE N.A.D, no phono stage, so needed phono inputs for records, as i was looking for a detailed sound, and the N.A.D's have such a great reputation for great sound overall, despite the grey (used to be brown) corporate, business type looks! LOL!! thanks for this demo.

This deck requires to desolder and clean both reverse switches - otherwise, it would not work reliably.

Still have mine. i bought it in 1994 from a secondhand store. The led screen didnt work correctly, from water damage. the signal was bleeding over from the next bank of leds. which is why i got it cheap. but it was an easy 5 min fix. the top solder joints were corroded together . i cleaned them up and made sure not cross connections and its still working after all these years.

Thank you

Good job👍👍👍

My auto return won't function. If I take the plater off, I notice the long triangular shaped arm will trigger it to auto return, if I pull it gently. Do you know which piece to adjust inside to trigger auto return? What's it called l, or can you describe it/process to adjust it on the PL-50?

Hi Alexis Can you please tell me where you bought the part number to restore this machine Thank you and wish you good health always

Hi Alexis, nice work! May I ask you where did you get the two pinch rollers? Their performace are very critical in that Sony serie and I have not reputable sources for them.. Many thanks!

I have a tascam 122 mkii. One of my levels is lower than the other on the VU meter. How would i know if its a low level signal or if the VU meter needs to be trimmed? Would i adjust the record level or playback level pot on the motherboard ? Its a bit confusing, I do have a good test tone calibration cassette if that helps?

Hi. I also have the same unit, it working however when side has most of the tape it start slowing down. What is your recommendation to solve this?

Good job Alexis! So in conclusion, is it a decent deck or not, what is your personal opinion on it? Merry Xmas from Bulgaria😊 and Efharisto.

Never do that! (scratched the top) What a bum job! There are much better solutions for such powder problems (e.g. AC INFINITY).

Good.
