Cary Audio CAD-280SA V12R

Really good coupling caps  do influence the outcome. After I did mine on my former V12R and now current Mono Tube amps, I could THEN truly hear the differences with input/output tube changes -and- interconnect changes too.

I had the R and you want the R version in my opinion.  Also, decooney is correct. Good luck!

Is there a version before I and R, and still a V12? I know where there is a  6922 version (thought it was the I), I guess it's an "I".  Is there  something before that? Early or late I.  I read the gain is different. the transformers are better and a sokey (sp) in the "R" and the signal tube upgrade 6922 to 12xxx series.

Just wondering.. There is a pair of monos for 5000.00 in the Ukraine.
Nice but too much.  I'd love another stereo V12R.at a good price. I'll keep my eye out... Tinkerfest...

Yes. Three versions.   Early V12, then V12i for 'Inspired",  & V12R for "Race".  Most "R" models were Red chassis.  The "R" had the larger "Blue Wire" transformer and the change on input tubes, the 6922 to 12BZ7 in particular. Some people sent in the "I" models to be upgraded and converted to the R version.  Upgrading the R further was even better.   

6L6 cheapo EH valves, broke in a bit  and sound really good now...
4 so so valves, sound great, Last 6L6, unit that sounded this good was a fresh MC240 with really good caps and PS upgrade. Couldn't get cheap valves to sound as good though. The Mac liked quality, well matched valves...

This amp, not nearly as picky. 6V6 next on the agenda.

What's the monoblock version like? Anyone have or had a pair?
Not a lot of those floating around.

 A second I or R would be a nice A/B after component swaps...and 
a great addition to another house system.

Patience..ya never know.. Any V12s collecting dust out there?...
