Fantastic vid! Great choice of parts. I built an EAR834 clone but from a different PCB about a year ago. I used all top notch parts and a toroidal transformer. Also separated the PSU from the main PCB with a separation “wall” inside the chassis. Also used copper tape throughout the inside. It turned out to have no hum or hiss. It sounds great! Thanks again for the great video! 🙂🎶🔊

I totally agree with the importance of the phono-stage's quality as being vital to bring out the best of what's actually on our L.P.s. I bought my own & very first s/h stereo at around 19'yrs old in 1980'ish after i moved into my first flat, it was a Thorens 150 t/table with it's original buyer's- fitted SME tonearm & KEF 3-way f/standers (Concertos) & a some make of integrated amp, from local s/h ad's ...way back when pre-eBay vintage hi-fi prices were dirt cheap & handy for an apprenticeship wage'd person as I was. After buying a 2'nd & then a 3'rd s/h integrated amp, out of sheer frustration because i'd heard my new s/h speakers & t/table combo both sound very good by the seller's home demo big-but, i kept remembering my own L.P.s tone sounding far better via a adopted clunky BSR auto'drop t/table plugged into the "Gram" input of an adopted old & large mono valved table-radio during my parent's bedroom listening -days. I quickly learned how varied & mostly unsatisfactory were the internal phono-stage circuits in the budget integrated amps that i'd bought tho their line-stages were all far more similar, by miles. The sound of that, my first stereo totally stood or fell by how the integrated amp's phono-stage performed & all varied greatly while most fell flat on their face, at least in my price range. Then I saw a cheap s/h Quad fully valved stereo pre-amp with 2 dedicated Quad II mono power amps for sale in a local ad & tho of a much older vintage, I bought it unheard (with a loose "bring it back if...", but all units worked well & my L.P. collection suddenly came alive like never before. A year or so later, i tried & then bought a s/h 3-box modular P.S. Audio dedicated phono-stage to play into the Quad valve pre tuner (or tape) line input... even better! & I felt i'd achieved something extra good for the first time & it was all down to the phono-stages i.m.firm.o. That was 35+ years ago & a decent phono stage has been a very important decision ever since. I now have a 2-box fully valved phono-stage / power supply (Ming'Da) I bought 12 to 15'ish yrs ago & it beat all previous contenders but it's not silent on M.C. setting (which a peak inside told me it uses extra valve gain for & not step-up trannies (& so hissy it seems a silly design but it sounds excellent on any good M.M. As an answer to that M.C. hiss (even on higher 0.5'mv MC's) So I later bought a Dynavector solid state phono stage for no hiss from my mono-M.C. fitted tonearm. Gr8 video. I'd love a fully valved phono stage that doesn't hiss on M.C.s but step-up trannies may not do it & home trials are out of the question here in Cambridgeshire, u.k.

Tell it like it is, Steph! Don't hold back 😎

best sounding phono preamp i had a separate power supply with a long umbilical cord it was dead quite. I put preamp on self power supply on floor.

I built a EAR834p clone. I scratched my head about loading of the MM cartridge. That required 47k and a capacitance of 200pF to 300pF. The phono lead could account for 125pF, but what did the phono input contribute? Studying how to calculate the Miller capacitance for a stage with a gain of about 50x gave a figure around 100pF. For a circuit with passive equalisation that would be it. Simulation of the circuit showed the gain of the first stage was only about 5x. This is because the feedback is summed at the point between the anode of valve 1 and the grid of valve 2. This reduces the voltage gain of the first stage. This in turn reduces the Miller effect by the same proportion. So the input capacitance is of the order of 15-25pF. Clever that! So strapping a 100pF across the 47k load gives me a cartridge loading of approximately 250pF. At last I can close the box.

good to revisit old projects don't use the chassis as you're electronics ground, couple you're electronics ground to the chassis via 10 ohm 4 watt resistor and a 100 NF condenser to the main cassis this will stop the 60 cycle hum and run DC heaters

Love your thought, I have always played vinyl as my main front, Thorens modified TD160 TT. Many tube amps though quiet had not the speed needed to bring music to life. I have huge horn speakers and a great integrated tube amp. Poor components creation jitter, hum, and low life. Used great capacities,great resistors . China stuff I have tried and been very disappointed.

Nice. I'm interested in this very much. I will follow to the end no doubt. Keep up the great content

Looking forward to this 👍

Johnnie back again . You still are great video lady . What is the total cost of parts and where to get it all

I would love to compare a EAR834 clone to my Hagerman Cornet 2 .

Having a schematic would be nice of what your are building would be great.. Where did you get the parts in this build?

Id be willing to buy 9ne from you. I don't have the time to build one

Great ! Thanks

Vinyl rules despite of kracking or plopping or wow and flutter. My phone and vinyl doesn't do that at all. The soundstage is much wider and more depth then my teac vrds10se and seperated dac. I use a phono tubestage passive riaa correction. I use direct current to the 12ax7 's for heater. Then you won't get any hum. It is too delicate to heat with ac. I use one 12ax7 per channel not more tubes less is better.

What little I know, I'd separate the granny from the circuit & place in a separate from the main chassis. Upgraded parts is a plus! Also, how much is this project total cost? I wish you success!

I must have missed the kit name or the specific one you ordered off eBay. I'm intrigued to build one myself.

Can anyone assist in identifying the correct circuit board and/or kit to buy on ebay that matches what is being discussed in this series of videos? Thank you.

Do you sell them ?

Oh NO !! An Lp will sound a million times better than a CD if you have a 1/2 ass decent System

A Chinese 834 knock off isn't the way to start. The values and circuit design are not close to the original $2500 design. Adding somewhat decent parts to a flawed circuit isn't going to add anything of value. I suggest that you seek out a decent phono preamp to examine and discuss.
