Re: Bob Carver ‘Black Magic’ VTA 20S Tube Amplifier Review from Dagogo.com ...
Chris
I think you can tube roll fairly simply with the Carver. I just think he runs his EL-84/6BQ5's at a higher voltage, which means there life expectancy is less. Rolling the driver tubes won't hurt anything they just may not last very long. At the price of some of the tubes mentioned earlier in the thread you just need to know that going in. Since that amp is "auto biasing", what are they auto-biased at. Roger's amp is biased at 30mv. I would suspect the Carver is a bit higher. I still think I would contact Roger directly at his forum on AC and ask him. He seems to be willing to answer any question about anything tube amp related.

I didn't realize it's self-biasing so you can't just set the bias low before putting in new tubes and then bring it up to the proper level. Like Jack said, you don't want to go blowing out $100-200 tubes as soon as you put them in.

I don’t understand the whole iPhone app to control the amp approach. I like a good old fashioned remote. The new Rogers amp we have in the store is all “app to control it”. No remote. Guess what?...
