Yeah, so I found out the amp I just bought is a 70s Mark I combo equipped with a EV SRO speaker.
At first I had trouble dialing in a good tone. I think the trick is not to turn both preamp vols up too high. I took out the Chinese tubes and put in a pair of NOS Tung Sol 5881s and some good USA pre amp tubes.
After playing with the vols a bit, this little amp screams! Notes holding out forever. Very pleased. Anyone else hip to the Mark ones?
