I have owned a pair of Tubeguru GM70 monoblocks for over a year now. Each amp has two GM70 output tubes and puts out about 45 watts.

I'm using them to drive modified Altec 604e speakers and they do a great job. Overall I feel that the sound is full bodied and that the midrange is all there in a way that I had not heard before with my other amps which was a pair of MFA M120D (modified by Scott Frankland). I also tried a Shindo el84 based amp but they did not pair well. I'd characterize the sound as thin so I sold the Shindo.

I've never tried 300b amps in the Altec because I wanted to use only amps with more power. I have two Don Allen amps, one with 2A3 and the other with 45 tubes but the Altecs still did not sound as good as they should. So in my own experience the GM70 amps work extremely well with my Altecs.
