Raven Audio Tube amps

Hi willgolf, I have the Blackhawk from Raven Audio (since June 2015) and can report I'm very happy with the amplifier as well as with Raven Audio's owner,  Dave Thomson. Mine was an upgrade from my Denon AVR3802 system and my entry into tube which was something I put off doing for years, despite listening and research.

What got me was Dave's willingness to answer my questions, to accommodate a try-before-buy, and awesome service. I also like that it is manufactured in Texas. What nailed it was his passion for the product. I'm certain when/if I upgrade again I will go back to Raven.

I paired my Blackhawk with an NAD M51 DAC and still need to add a phono preamp. I have no hesitation in recommending Raven Audio to you.

Good luck!

I should add: I drive a pair of Energy CF-30 speakers with the Blackhawk (90dB) and a sub as well using the Blackhawk's sub-out.

It's way more powerful than my room and listening levels, but I suspected it would be. (20W in analog blows away the transistorized Denon 110W which is what I expected.)

I went the extra dollars for better sound. I chose it for its self-biasing design and like the integrated design.  Also the motorized remote volume control is cool.

I shared the following in another forum:

If interested, here are the tubes in my Blackhawk (directly from Raven, not rolled):
1. Preamp stage, 12AT7: both RCA, left marking: 67 43, USA 6201; I think this indicates mfr'd in 43d week of 1967. Can only make out RCA on rightside
2. Power amp first stage, 12AT7: both GE, left 57 43 (and 188-5 marking?); right GE, 58 4 (1957 and 1958 resp, I think.)
3. Phase inverter stage, 12AU7: both Philips ECG/USA, both say JAN 5814A, right-side says 8813 APX

Power tubes, 6L6GC, made in Russia, (written in English), all say OTK 61, Front/right 1103, Front/left 1115, Back/right 1050, Back/left 1115. These aren't date codes as I bought the amp 6/2015

Any help in further translating this information is welcomed!

Adding: the two 6L6GC pairs are Winged C stamped =C= which indicate Svetlana/St Petersburg.
