Picked up a traynor yba-1a mk II last month. It was in near mint condition and running the original tubes. I took it to a local guitar shop that services tube amps and they checked it over 100%. I had them add a three prong plug, it needed the fan bearing repacked, and a new pre amp tube. They also bench tested it and it showed 85 watts, which the owner was amazed at out of the two power tubes. Now my main questions is which input should I be using for bass? It has 2 I inputs and 2 II inputs. Also can I drive my svt 810 with this? I know it's rated to 8 ohms and the svt is 4 ohms. I don't want to. Have blowing the Hammond ot since they don't make the like they used to. I was thinking of buying a ampeg v4 that I found for 400 or an svt classic I found on gc for 699 to drive the svt. The Traynor did come with a yb-18a, which is a folded design 18 that runs at 8 ohm. Problem is the tolex and grill smell like a cigarettes do bad it's annoying. I got most off the tolex but the grill will need replaced.
