Audio Research VS110, VS115?

Hi Daveyf and Fsonicsmith,

Thank you so very much for your useful information!

Daveyf, once putting new tubes into the D70 and having it biased, how long, on average, will the amp once again require biasing?

Thanks,

Adrian

Many kind thanks to my fellow audiophiles on Audiogon and your very helpful submissions!(6550C, Bjesien, and Daveyf)

Hi,

Once again, thank you for all the great insight you provided!

If I were to once again, purchase a D70, how difficult is it, not to mention risky, to bias this amplifier.

You see, the D70MKII I bought years ago, from a friend, had the bias performed on it just prior to me aquiring it. The friend I purchased it from told me as much. He also stated that with average use it would not need to be biased again for quite a while as the tubes were fairly new.

Long story short, I regrettably ended up selling the amp before it needed this sort of attention. This aspect of it I no doubt, found "somewhat intimidating", to say the least. This, in a large way, was probably responsible for its sale.

Please respond,

Many thanks,

Adrian
