DIY Loudspeakers: HOME INDEX UPDATES RESPONSE WHAT'S NEW

EAR-869 SE tube amp |
I found a 2nd hand mint condition EAR-869 at a reasonable price and
couldn't resist the temptation to own a low-wattage SE amp for testing
high-efficiency speakers and also hear what this simplistic tube amp
featuring the very familiar PL519 tube could do here. This amp dates
back some almost 30 years and was initially launched as a 13 wpc
EAR-859, either ready-built - or as a kit. Some call it a SET amp as the
519 tube is wired for triode opration. Whatever!
Run as an integrated amp I connected my MSL cartridge to the van den Hul
The
Grail phono stage and plugged it into the phono input - and the
total gain of the amplifier is enough to not turn the volume pot up to
more than 10-11 on a clock scale. I haven't measured the total gain yet. Specs says 500 mV for 15 watts. As can be seen from the schematics below, there is no
line stage as such; run as a power-amp is just by-passing the input and volume controls.
Contrary to the other EAR products I've bought, this amp comes with a
substantial manual with lots of advise on set-up and other issues.
Read Ken Kessler's review of the -859 here. (yes, eight-five-nine, dating back from the beginning of the 90'ies).
