FWIW, the Coda No.11 has achieved a near legendary status among some.
I would not hesitate to buy one for a reasonable price, and that’s even despite the fact I was ultimately somewhat disappointed with a newer No.8.
You should also consider the restored/upgraded Yamaha B-2 VFET amp for sale here. It will likely compete with anything remotely near your budget. I know for a fact it would stomp the Hegel 160.
