That's funny. And the old adage, if it ain't broke don't fix it. Or be more nimble with a test probe!!! Zaaaaaaaaap. If I was a good as you in using a meter I'd be dead on teh voltages I work on.....poooooof. Send it back and just say it don't work, play dumb, in your case it may not be playing!!!!!!

So I got my "new" Marantz 2270 serial no 11754 and decided it would be
a good idea to check the DC offset. One channel was at 70mV and the
other was at 30mV. Not bad, but enough to bug me since it seemed like
a simple enough fix. I found the manual online and was first going to
check the voltage on J802 like it says. Well I managed to short out
J802 to the ground (puff of smoke came from somewhere around the
middle cap). I turned it off and back on and everything seemed to work
fine so I proceeded to get the offset to 0 for both channels. Now one
Hi all,
I have a new Cayin A-88T integrated amp. It is my first tube amp, and really sounds magnificent... so of course, I was wondering what tubes you might suggest to make it sound even better.
I prefer a balanced sound - clean and detailed, with equal measures of musicality and warmth. I listen to a wide range of music (electronica, acoustic, rock, classical), and assume some tubes might be better suited for my needs than others.
It uses:
(4) KT-88 / 6550
(2) 6SL7
(2) 6SN7
Many thanks,
Bill
Ironically enough, "stereo" is defined as two or more speakers, not just two, though "stereo" has garnered a colloquial meaning of two channel over the years.
