I know this console and relocated one in the 1980's. I will point out that in typical RCA fashion, all of the 1R and 1C numbers relate back to a parts list that will be more specific about the values. Also keep in mind that these consoles were mostly used in AM radio broadcast (sometimes FM) and not recording, so while they wanted it rugged and well built, the fi didn't need to be too high, just reasonable. They were really just for announcers and news broadcast. This is a preamp, that would work for years without any need for attention. Many of these ran non stop for 40 years, and mostly needed output tubes changed from time to time. Preamp tube ran a lot longer.

I bought one of these for £350, fully refurbished it, runs very very well, so well I kept it and fitted a 1024g. Amazing deck and the engineer should get to know things better before slagging it off. Setup properly the sound from these is exceptional.

What year did this model come out? I've bought one same as this and is curious on how old it is!

Que válvulas usa ese dansette

Hello sir please tell me the dimension od garrand 301turntable

good istruzion now ave mor dettails for test onestely befor not ave good consideration in this instrument buth now is different

Simply WRONG. The meter is zeroed by adjusting the anode current controls. You should never alter the grid voltage when testing a valve.

Very Nice!… Did you ever get it playing?… Or work out what exactly it was?

The Reason each speed is locked (Cant change speed when running) is the idler wheel operates at different heights 33 /45 /78 the idler would be damaged rapidly without the turn off to change speed function.

do you service Quad IIs? Can yo8u recommend someone in Europe (contiental europe or UK)

I wish all videos were this comprehensive, intelligent, and well-paced.

Picked a new amplifier from one of these up which had never been put into case on ebay!

EF 86 daft Mullard gimmick, 6sn7 better octal base connections and good triode input

Actually there is an argument for pure pentode/pure tetrode amplifiers. There's more power available and less pick-up to and from the extra transformer wiring. All amps modern and new should be as simple as Reasonably possible! They never really needed to twist wires to stop heater hum or have hum bucklers - split plastic casing shorting out heater lines and burnt out transformers respectively can result. And modern switch mode power supplies to power heaters can just result in rf noise (not always) apparent, but just distorts audio! All you need is on side of parallel heaters to deck on each valve holder and common wire connecting All heaters. Modern op amps make good preamp anyway which don't need heater supplies!. But it's daft putting microprocessors into valve amps, these are in your cd player which plugs into the valve amp. There's even a daft £200, 000 20Watt stereo amp out therewith uses old 300b tubes (not designed as audio tubes) and microprocessor technology for USB input!

Great videos

Gread videos😊

the input wasn't only a potentiometer. Sometimes they used a step attenuator. These were preceeded by the mic input transformer which connets to 3&4.That's where all those Daven attenuators you see on ebay come from. To us they were just service parts.

Regarding the zero of the meter, Isn't it the anode current what should be adjusted and the not the negative grid volts

On a Major I had, the transformer was a part of the motor stator windings. Plus I think it might have been an auto-transformer, not isolated. Also there was no cartridge muting switch on the changer, and it was just ordinary wires, not screened.

Excellent video thanks

I've got four that were rescued from a demolished theatre/cinema and all appear complete. The only issue seems to be the iron chassis are bent where presumably heavy equipment came into contact with them. That metal is really tough! Thanks for this, and it will help immensely with the refurbishment project.

Do you know the value in henry of the smooting choke L1?

Great explanation

Awesome

I've got the book, im about to have a go at this project, thanks for your video

Excellent video thanks 😊

This video is totally brilliant. Thank you for making it in a world of opinion.

Благодаря ви.

I just acquired one from a friend, I don’t think it works but I am in the process of cleaning it and will most likely have it as a display piece in my den.

太老實啦，推挽就只得10W？淘宝的吹到輸出8欧姆接喇叭，有25W的啊！🤣🤣

Nice video. Keep it coming... I have a question. What good will it do having two tube rectifiers? I know one is enough. Thank you for your time.

Brilliant vintage record player great sound I always thought the BSR UA8 was the best looking turntable with the gold tone arm and balancing arm and the flag record size selector and the Bakelite round speed control and stop start and reject knobs very aesthetically pleasing turntable

Good video, I've used a ECL84 tv valve as a simple audio amplifier, it worked well 👍

I want that Phil Spector sound back i miss it

I am building the Mullard 5-20 amp which is very similar to the 5-10 . I am puzzled by the lack of a value for the resistor between the main t/f and the rectifier valve . I have , in my circuit 100ohm here but the HT voltage is 100volts too high . What should I do to lower this .???

Thank you so much for this video, it really encourages me to get more involved

Very educational, i've just acquired my 2nd set of Quad II amplifiers....... ruclips.net/video/P5EBRPhdgcA/видео.html

Just a thought. The sub chassis for the KT66s was resect so the KT66s would not be damaged should the amplifier be up turned.

Considering buying one of these, Beautiful looking jukebox and stereo as well. Although I doubt you could buy stereo 45s back when this was made

thank you for making such a great video

Good work

Nice diagram

Would you know what capacitor i would need for a ECL82, It's a classic ford car radio, Only trouble i have is the faulty capacitor i removed is blank with no writing on it.

when i look up the settings for the dial i am seeing ** in the book what do i use for this

I've been running a stereo ECL82 amp nito a pair of Audio Note K speakers as a monitor system for recording for 20 years this years and its shear beauty! I must say, that circuit is a clever way of saving money and getting a richer, fatter sound out of the small eliptical speaker. We live in an age where such things are not really a consideration and its nice to see how using things like an inverting valve stage against itself to reduce hum was actually a thing back then!

I bought one if these together with the au stereo amp a couple of days ago from a charity shop for 80 sobs. It's missing the cable to connect the amp to the record player, the speed appears to be stuck on 33 and doesnt play on auto. The stylus could do with replacing (it wont play new vinyl discs at all). Other than that, I love the look, the smell and the sound- albeit a little rough. I'm hoping a new stylus will make all the difference, together with the correct lead for the au51 if only I was certain what I need to order. Any advice would be very much appreciated.

i sadly dont understand that much.... my bush got a realy low sound outpout from the peaker and quite distorded....
