Hey (again) CB101:
It is a great amp. Like you; the Lonestar and the DC-5 are the two Mesa amps I own. The clean channel doesn't actually sound like the Lonestar's to me...but it is an equally nice one. The distortion channel is a little 'too-much' (for me)...but it can be 'tweaked' if desired.
For any info on it and tweaking...'Monsta-Tone' is the guy to consult. Check out his many postings on the DC-5 and DC-10 in the 'Vintage Amps' (Before 1991) Forum.
I have a little experience 'tweaking' it...although far less than 'Monsta-Tone'.
The first time I tried Yellow-Jacket EL84 Adapters I was disappointed in the results...(far too mushy) Tried 6V6s and they sounded cold and sterile.
Replacing the 12AX7 in the Phase Inverter socket with a 12AT7 smoothed out the Yellow Jacket/El84 sound wonderfully. Also the 12AT7 sounded better for the 6V6 as well (to me)...but it was also necessary to use the 4-ohm -speaker-out when using the 6V6s (just as in the Lonestar).
I found the 2nd channel a little 'over the top' for my tastes...it may be just fine for you. If not...try a 12AY7, 12AT7, or a 5751 in the 2nd/3rd gain stage for channel-2. Even a DW7 may work. I use a 12AY7 currently.
The Phase Inverter is the pre-amp tube to the far-left (the 6th socket). The channel-2...2nd/3rd gain stage tube is the second tube from the RIGHT...i.e. the 2nd tube socket.
You may not need any of this info...but like I said if you wanna really learn about the amp consult 'Monsta-Tone' and his many posts.
