That's a nice little amplifier - mostly point-to-point wiring, about 25 watts per channel. You should be able to do some tube rolling with it. There are a variety of EL34 tubes, and you might be able to use KT77s as well, which could give you a little more extension top and bottom. There are reviews on Dagogo, Possitive Feedback and Six Moons. I agree with Brownsfan, despite his questionable taste in football teams, don't discount the importance of the rectifier tubes. They definitely can have a positive effect on the sound.
Where for a tube-newb to start?
I have inherited my first tube amp, an Eastern Electronics M520. There is a description of the system at eeaudio.com, but the component "names" (12AU7, GZ34/5AR4, EL34) mean nothing to me (yet). Can anyone point me to a good article on tube amps and tube reviews?
Thanks!
Thanks!
