Big difference

Personally, the Studer A820

 

[christensenleif@msn.com]

I want to go external repro amp and is basically after the optimal transport
using an A820 or a Nagra T as a mere trnasport might be a little steep for me as a starter
will the A80RC mkII do...or will I miss something?
and yes , I think the rest of my setup is up to it

A820 and A80RC the transport is the same only the amp of A820 use more ICs and same design to A810. A810 that you can use the record head to play back just switch to SYN but not too sound good as well, if you do not want to do recording then special order a 4 track repro head to replace the recording head for A80RC with a out broad amp will do the job

ok good news thxs!
where do I special order the 4 track repro head?
ok can switch head for the repro amp then....

If only one? It would have to be the Studer A80RC MkII
So simple to work on, calibrate and maintain. My opinion, with few modifications, it's the best sounding Studer.

This forum should have a smiley for Applause!
Does your A80 have any modifications other than the external head amplifier?

I really liked Charles Stellavox portable tape machine...a lot!

A80 is starting to tickle my senses.......looking fw to wednesday
then the repro amp mission.....

A820 and A80RC the transport is the same...

Tony,

I would respectfully differ, here. Find photos of the A820 and compare to the A80 RC MK II.
The tape paths and hence, transport, are not identical.

Heads can be ordered and custom made by JRF Magnetics

Ki has waved his magic wand over it and I also have custom Flux Magnetics ER heads, Athan rebuilt motors and bearings/pinch roller and a secret sauce!

John at JRF added a 1/4" 4-tk Flux repro head to my A80 VU...little switch on top of the headblock selects 2-tk stereo or 4-tk playback. Really woke up some of those consumer 7" reels.

sorry I clear the space already now, and I saw your phono design, do you use a MM cart or a MC step up in front of the in-put? in my experience I will like to use triode tube for better sound and transformer coupling not cap, and I wonder both of your tubes design have enough low impedance to drive 600 ohm LCR and out put to line stage ? because they use plate for out put (pentode has high impedance that will cost noise problem). but so far if you have no problem of your amp then you can try to replace the LCR filter to see how it sound but they have to be same 600 ohm, if gain is not enough then add a 1 to 10 step up transformer in front, now I only worked out the value of NAB LCR filter (test done) for CCIR is not yet

I use a Lyra Titan "i"
the riaa has 2 inputs:
one for mm where the Titan is connected via a Lyra Erodion transformer
the other has an inbuilt S&B transformer
the riaa section meets line lvl signals in a seiden source selector switch, which routes the signal straight to a S&B TVC that drives my amps
NO noise, even at full volume, cartridge out of groove , into 112 db sensitive horn system
so would be interesting to test either straight passive CCIR curve or even better LCR version

picked up this little sweetie today

Congrats on your newest addition to the family!

btw butterfly heads, but I guess \I´ll survive

probably getting my UltraAnalogues tomorrow....perfect timing

Looks like an old BBC unit. The machine and capstan look in reasonably good shape. I'd change out the pinch roller, clean it up some and go from there.
