HmmmYep. Good tubes. I put them anywhere they fit.
Concur. I only run Mesa tubes in my Road King. Never even considered anything else. Price but if you buy direct from their hollywood store, their customer service is EXCELLENT.In a word...yes. I’ve tried other tubes in my Mesa’s over the last 20 years and I always end up back with the Mesa-branded tubes. They sound best and seem to last longer, plus Mesa amps are fixed bias and you know you’re getting a perfect match with the Mesa tubes.
I’ve used them in Marshall and Rivera amps too and gotten excellent results.
